Muscles of the Leg that Move the Foot and Toes

Los músculos de la parte inferior de la pierna que mueven el pie y los dedos del pie se pueden dividir en los compartimentos anterior, lateral y posterior.
El compartimento anterior incluye el tibial anterior, el extensor largo del dedo gordo, el extensor largo de los dedos y los músculos peroné terciario.
Estos músculos flexionan dorsal el pie. El tibial anterior se invierte, mientras que el peroné tercio, lo evierte. Además, el extensor largo del dedo gordo y el extensor largo de los dedos se extienden por el dedo gordo del pie y otros dedos, respectivamente.
El compartimento lateral alberga el peroné largo y el peroné corto que se flexionan plantar y everten el pie.
Los músculos del compartimento posterior se dividen en capas superficiales y profundas.
La capa superficial posterior tiene el gastrocnemio y el sóleo, lo que permite la flexión plantar. El gastrocnemio también flexiona la pierna. El plantar, un pequeño músculo que puede estar presente en pares, flexiona el pie.
Los músculos de la capa profunda posterior plantar flexionan el pie, excepto el poplíteo que rota medialmente la tibia.
Además, el flexor largo del dedo gordo y el flexor largo de los dedos flexionan el dedo gordo del pie y otros dedos, respectivamente. El tibial posterior supina el pie.

músculos de la pierna que mueven el pie y los dedos

La pierna humana comprende un intrincado sistema de músculos que facilitan el movimiento de los pies y los dedos. Dentro de este sistema, los músculos se clasifican en los compartimentos anterior, lateral y posterior, cada uno con un conjunto único de músculos que realizan funciones específicas.

Compartimento anterior

El compartimento anterior incluye músculos que contribuyen a la dorsiflexión del pie. Este compartimento alberga los músculos: tibial anterior, extensor largo del dedo gordo y extensor largo de los dedos. El músculo tibial anterior, situado a lo largo de la superficie lateral de la tibia, se palpa fácilmente y es el más grueso. El tibial anterior también provoca la inversión del pie. Además, el extensor largo del dedo gordo y el extensor largo de los dedos extienden el dedo gordo y otros dedos del pie, respectivamente. El músculo peroné tercero, que se origina en la misma fuente que el extensor largo de los dedos, también está presente aquí. Provoca la eversión el pie.

Los calambres en las piernas, médicamente conocidos como síndrome de estrés tibial medial, son una aflicción común entre los atletas, especialmente corredores y bailarines. Resulta del uso excesivo y el estrés repetitivo de los músculos del compartimento anterior. Las medidas preventivas incluyen estiramientos regulares, entrenamiento de fuerza y elección del calzado adecuado.

Compartimento lateral

El compartimento lateral contiene los músculos peroné largo y peroné corto. El peroné largo es el más largo y superficial de los dos músculos. Se origina en la cabeza y la porción superior del peroné, el exterior y más delgado de los dos huesos de la parte inferior de la pierna, y los tabiques intermusculares adyacentes. El peroné corto, que se encuentra justo debajo del peroné largo, es más corto y se origina en los dos tercios inferiores del peroné. Estos dos músculos ayudan en la flexión plantar y eversión del pie.

Compartimento posterior

El compartimento posterior se divide a su vez en grupos de músculos superficiales y profundos. El grupo superficial incluye los músculos gastrocnemio, sóleo y plantar, comúnmente llamados músculos de la pantorrilla. Estos músculos comparten el tendón de Aquiles, el tendón más robusto del cuerpo, que se inserta en el hueso calcáneo del tobillo. La postura erguida humana se atribuye al tamaño de estos músculos. El gastrocnemio forma la parte prominente de la pantorrilla, mientras que el sóleo, que se encuentra debajo del gastrocnemio, tiene una apariencia plana y ancha. El plantar, un músculo pequeño, se encuentra entre estos dos músculos y está ausente en algunos individuos.

El compartimento posterior profundo alberga los músculos poplíteo, tibial posterior, flexor largo de los dedos y flexor largo del dedo gordo. El poplíteo forma el suelo de la fosa poplítea. El tibial posterior es el músculo más profundo del compartimento posterior, ubicado entre los músculos flexor largo de los dedos y flexor largo del dedo gordo. A pesar de flexionar solo el dedo gordo del pie en la articulación interfalángica, el flexor largo del dedo gordo es más grande que el flexor largo de los dedos, que flexiona los otros cuatro dedos.

KEY TERMS AND CONCEPTS

TÉRMINOS Y CONCEPTOS CLAVE

leg muscle groups for foot motion

The leg muscles that move the foot and toes are organized into the anterior, lateral, and posterior compartments. Each compartment has a distinct set of muscles with its own actions. Together, they control dorsiflexion, plantar flexion, inversion, eversion, and toe movement.

The anterior compartment includes the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and fibularis tertius. The tibialis anterior runs along the lateral surface of the tibia, is easy to feel, and is the thickest muscle in this group. It dorsiflexes the foot and also helps invert it. The extensor hallucis longus extends the great toe, while the extensor digitorum longus extends the other toes. The fibularis tertius comes from the same source as the extensor digitorum longus and helps evert the foot.

This compartment is also linked to shin splints, which are called medial tibial stress syndrome. It is a common problem in athletes, especially runners and dancers. It is caused by overuse and repeated stress on the anterior compartment muscles. Regular stretching, strength training, and proper footwear can help prevent it.

The lateral compartment contains the fibularis longus and fibularis brevis. The fibularis longus is the longer and more superficial muscle. It starts at the head and upper part of the fibula, which is the outer and thinner lower-leg bone, along with nearby intermuscular septa. The fibularis brevis lies beneath it and begins on the lower two-thirds of the fibula. These muscles help plantar flex and evert the foot.

The posterior compartment is divided into superficial and deep muscle groups. The superficial group includes the gastrocnemius, soleus, and plantaris, which are often called the calf muscles. These muscles share the Achilles tendon, the strongest tendon in the body, and it attaches to the calcaneal bone at the ankle. Their size helps support the upright human stance. The gastrocnemius makes up the main bulge of the calf, the soleus lies beneath it and has a flat, broad shape, and the plantaris is a small muscle between them that is absent in some people.

The deep posterior compartment includes the popliteus, tibialis posterior, flexor digitorum longus, and flexor hallucis longus. The popliteus forms the floor of the popliteal fossa. The tibialis posterior is the deepest muscle in this compartment and lies between the flexor digitorum longus and flexor hallucis longus. The flexor hallucis longus flexes the big toe at the interphalangeal joint, and it is larger than the flexor digitorum longus, which flexes the other four toes.

the muscular system

Muscles, Bones, and Body Movement

The muscular system helps the body move, stay stable, and carry out internal work. It includes three kinds of muscle tissue: skeletal, smooth, and cardiac muscle. Each type has a different role in the body. Skeletal muscles are under conscious control, so people can move them on purpose. They attach to bones by tendons, and their contraction and relaxation make actions like walking and lifting possible. These muscles also produce heat during physical activity, which helps maintain body...

fascicle arrangement in skeletal muscles

How Muscle Fiber Layout Shapes Movement

Skeletal muscle fascicles are bundles of muscle fibers, and their layout helps determine how a muscle moves. The way these fascicles are arranged affects both power and range of motion. Different arrangements give muscles different mechanical strengths. Parallel muscles have fascicles that run parallel to the long axis of the muscle. Common examples are the biceps brachii and the rectus abdominis. When these muscles contract, they shorten and become wider. They can shorten by about 30% of...

muscle coordination and action

Muscles That Work Together in Movement

Muscles work together to create smooth, purposeful movement. Actions such as flexion, extension, adduction, abduction, and rotation depend on this coordination. The body uses several muscles in a controlled way so joints and bones move as needed. Four functional roles help describe how muscles act during movement: agonist, antagonist, synergist, and fixator. An agonist, also called the prime mover, is the main muscle that produces a specific motion. During a bicep curl, the biceps brachii is...

naming skeletal muscles

How Muscles Get Their Names

Skeletal muscle names are built from features that help identify each muscle. The names of the roughly 700 muscles in the human body can point to where a muscle is found, what it looks like, or how it works. That makes the names easier to learn and remember. Many muscle names describe the region of the body. The temporalis muscle is in the head region, while the brachialis is in the arm. Other names describe position and depth. Muscles near the surface may be called externus or superficialis,...

axial and appendicular muscles

Muscles for Movement and Body Support

Skeletal muscles support movement and body structure. They are grouped into axial muscles and appendicular muscles based on where they are found and what they do. Axial muscles lie along the body’s midline. They connect with the axial skeleton, which includes the skull, spine, ribs, and sternum. These muscles help with facial expressions, head and neck movement, speaking, and eating. They also help control movement of the vertebral column with the back muscles. The trunk also contains...

muscles for facial expressions

How Facial Muscles Shape Expression

Facial muscles shape human expression by moving the skin of the face and scalp. These craniofacial muscles are thin skeletal muscles that lie just beneath the skin. They help create the nonverbal signals people use to show emotion and intention. There are about 20 of these muscles. Most begin on bones or fibrous parts of the skull and then extend outward to attach to the skin. They are called muscles of facial expression, or mimetic muscles, because they reflect feelings through movement. <br...

muscles of the eye

Eye Muscles and How They Focus

The eye muscles control movement, focus, and eyelid opening. The human eye uses ten muscles: six extraocular muscles, three intraocular muscles, and one main eyelid retractor muscle. The six extraocular muscles sit around the eyeball and move it in different directions. The lateral rectus pulls the eye outward, and the medial rectus turns it inward toward the nose. The superior rectus and inferior rectus move the eye up and down, while the superior oblique and inferior oblique rotate the eye.

muscles of the anterior neck

Anterior Neck Muscles by Region

The anterior neck muscles are grouped by where they sit in the front of the neck. They include superficial muscles, suprahyoid muscles, and infrahyoid muscles. This layout helps show how the neck muscles are organized around the hyoid bone. The superficial muscles are the most visible muscles in the front of the neck. They include the platysma and sternocleidomastoid, often called the SCM. The platysma is a broad, thin muscle that stretches from the chest and shoulders to the lower jaw and...

muscles that move the head

How Neck Muscles Guide Head Motion

Neck muscles guide head motion by working together to bend, turn, and lift the head. They help with rotation, flexion, extension, and lateral bending. The sternocleidomastoid, or SCM, plus the suprahyoid and infrahyoid muscles are major head flexors. The SCM runs from the sternum and clavicle to the mastoid process of the temporal bone. When both SCM muscles contract, they bend the head forward. When only one side contracts, it bends the head toward that side or turns the head to the opposite...

muscles of the vertebral column

How Back Muscles Support Spine Movement

Back muscles that lie deep to the thoracolumbar fascia are called intrinsic, or true, back muscles. They are grouped into four layers. These layers are the superficial, intermediate, deep, and deepest layers. The superficial layer mainly includes the splenius muscles. These are the splenius capitis and splenius cervicis. They help move the head and cervical spine by supporting extension, rotation, and lateral bending. The splenius capitis runs from the upper thoracic and lower cervical...

muscles of the thorax

How Thorax Muscles Drive Breathing

Thorax muscles help breathing and support movement in the upper body. They also help keep the chest stable. Together, these muscles make the rib cage move while the lungs fill and empty. The diaphragm is the main breathing muscle in the thorax. It is a wide, dome-shaped muscle that separates the thoracic cavity from the abdominal cavity. It starts below the rib cage and lumbar vertebrae and attaches to the central tendon. When it contracts, it flattens and moves downward. This increases the...

muscles of the abdomen

Abdominal Wall Muscles and Support

The abdominal wall muscles support the abdominal cavity and help protect the internal organs. This flexible wall is bordered by the xiphoid process and costal margins at the top, the vertebral column at the back, and the pelvic bones and inguinal ligament at the bottom. It is divided into the anterolateral region and the posterior region. The anterolateral region includes five paired muscles in two groups. The lateral group contains the external oblique, internal oblique, and transversus...

muscles of the pelvic floor and perineum

Pelvic Floor Muscles and Continence

The pelvic floor and perineal muscles support the pelvic organs and help control continence. They also play roles in sexual function, childbirth, and core stability. These muscles are usually divided into a superficial perineal layer and a deeper pelvic floor layer. The perineum is a diamond-shaped area below the pelvic diaphragm. It is split into an anterior urogenital triangle and a posterior anal triangle. The urogenital triangle contains the external genitals and includes the superficial...

muscles of the shoulder

Shoulder Girdle Muscles and Scapula Motion

Shoulder girdle muscles stabilize the clavicle and scapula, and that support helps the humerus move efficiently. Scapular movement also works with humerus movement and extends the arm’s range of motion. Raising the arm overhead depends on upward rotation of the scapula. The anterior thoracic muscles include the serratus anterior, subclavius, and pectoralis minor. The serratus anterior, often called the boxer’s muscle, starts on the first to eighth or ninth ribs and inserts along the superior...

muscles that move the arm

Arm Muscles and Their Movements

Arm muscles move the humerus through flexion, extension, abduction, adduction, and rotation. Nine muscles help produce these arm movements. Two of them, the pectoralis major and latissimus dorsi, come from the axial skeleton. The other seven begin on the scapula and are called scapular muscles. The pectoralis major has two origins, or heads. Its clavicular head starts on the medial half of the clavicle. Its sternocostal head starts on the costal cartilages of ribs 1 through 6, the sternum, and...

muscles that move the forearm

Forearm Muscles for Elbow and Rotation

Forearm muscles help the arm bend, straighten, and rotate at the elbow and radioulnar joints. They are grouped as forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint. The pronators and supinators act on the radioulnar joints. The forearm flexors are the biceps brachii, brachialis, and brachioradialis. The biceps brachii has two heads. Its long head begins at the supraglenoid tubercle of the scapula, and its short head...

Forearm Flexors, Extensors, and Wrist Support

The forearm muscles that move the wrist, hand, and fingers are grouped into anterior and posterior compartments. These muscles work together to bend, straighten, and stabilize the hand and digits. They also connect to the bones of the wrist and hand in organized layers. The anterior compartment contains the flexor muscles. These muscles usually start at the humerus and attach to the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis, palmaris longus,...

muscles that move the thigh

Hip Muscles That Move the Thigh

Hip muscles control thigh movement by connecting the pelvic girdle to the femur. The iliopsoas is one key muscle group. It is made of the psoas major and iliacus muscles. Both share a common insertion on the lesser trochanter of the femur. The gluteal muscles also play major roles. The gluteus maximus starts on the posterior ilium, sacrum, coccyx, and thoracolumbar fascia. It inserts on the iliotibial tract and the gluteal tuberosity of the femur. This muscle is the chief extensor of the femur.

muscles that move the leg

Thigh Muscles Behind Leg Motion

Thigh muscles help move the leg through flexion, extension, adduction, and rotation. They are grouped into the anterior, medial, and posterior compartments of the thigh. Each group supports a different part of leg motion at the hip and knee. The anterior compartment includes the quadriceps femoris, the most visible thigh muscle group. It helps extend the leg and flex the thigh. The quadriceps is made of four muscles: vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris.

muscles of the leg that move the foot and toes

The leg muscles that move the foot and toes are organized into the anterior, lateral, and posterior compartments. Each compartment has a distinct set of muscles with its own actions. Together, they control dorsiflexion, plantar flexion, inversion, eversion, and toe movement. The anterior compartment includes the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and fibularis tertius. The tibialis anterior runs along the lateral surface of the tibia, is easy to feel, and...
