Muscles that Move the Thigh

Los músculos que mueven el muslo se originan en la cintura pélvica y las vértebras lumbares y se insertan en el fémur y la tibia.
El músculo iliopsoas es un importante flexor de la cadera que es una combinación de los músculos psoas mayor e ilíaco.
Hay tres músculos glúteos. El más grande, el glúteo mayor, extiende el fémur y lo rota lateralmente en la articulación de la cadera.
El glúteo medio y el glúteo menor se encuentran debajo del glúteo mayor y funcionan como abductores femorales y rotadores mediales.
El glúteo mayor y el tensor de la fascia lata se insertan en una banda gruesa de tejido conectivo, llamada tracto iliotibial o banda iliotibial, que estabiliza las articulaciones de la cadera y la rodilla.
Los músculos piriforme, obturador interno, obturador externo, gemelo superior, gemelo inferior y cuadrado femoral se encuentran profundamente en el glúteo mayor y pueden rotar lateralmente el fémur.
Los músculos aductor largo, aductor corto, aductor mayor y pectíneo se encuentran medialmente en el muslo y contribuyen a la aducción del muslo y a la rotación medial y lateral. Por lo general, un tirón en la ingle es una lesión en uno de estos músculos.

músculos que mueven el muslo

El movimiento del muslo está gobernado principalmente por músculos que se originan en la cintura pélvica y se insertan en el fémur. Un músculo crucial, el iliopsoas, es una combinación del psoas mayor y el ilíaco, y comparte un punto de inserción común en el trocánter menor del fémur.

Otros tres músculos importantes son el glúteo mayor, el glúteo medio y el glúteo menor. El glúteo mayor se origina en la superficie posterior del ilion, el sacro y el cóccix, y en la fascia toracolumbar y se inserta en el tracto iliotibial y la tuberosidad glútea del fémur. Actúa principalmente como principal extensor del fémur. Por el contrario, en su acción muscular inversa, extiende poderosamente el torso a la altura de la articulación de la cadera.

Los glúteos medio y menor se originan anteriores al origen del glúteo mayor y se insertan en el trocánter mayor del fémur. El músculo glúteo medio funciona como un potente abductor del fémur en la articulación de la cadera y es un sitio común para la inyección intramuscular debido a su ubicación accesible. Profundo al músculo glúteo mayor, hay seis músculos: el piriforme, el obturador interno, el obturador externo, el gemelo superior, el gemelo inferior y el cuadrado femoral, que funcionan como rotadores laterales del fémur en la articulación de la cadera.

Además, el músculo tensor de la fascia lata se encuentra en la superficie lateral del muslo, insertado en el cóndilo lateral de la tibia. Este músculo, junto con sus tendones y músculos glúteo mayor, ayuda a formar el tracto iliotibial. Como sugiere el nombre, este músculo está envuelto por la fascia lata, un tejido conectivo denso que rodea todo el muslo.

Por último, en la cara medial del muslo hay tres músculos únicos: el aductor largo, el aductor corto y el aductor mayor. Estos músculos se originan en el hueso púbico y se insertan en el fémur, aduciendo el muslo y demostrando la capacidad única de rotar el muslo tanto medial como lateralmente. El aductor largo también flexiona el muslo, mientras que el aductor mayor lo extiende. El músculo pectíneo también desempeña un papel en la aducción y flexión del fémur en la articulación de la cadera.

KEY TERMS AND CONCEPTS

TÉRMINOS Y CONCEPTOS CLAVE

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. In reverse muscle action, it also extends the torso at the hip joint.

The gluteus medius and gluteus minimus begin in front of the gluteus maximus origin and insert on the greater trochanter of the femur. The gluteus medius is a strong abductor, which means it moves the femur away from the body at the hip joint. It is also a common site for intramuscular injection because it is easy to reach.

Deep to the gluteus maximus are six lateral rotator muscles. These are the piriformis, obturator internus, obturator externus, superior gemellus, inferior gemellus, and quadratus femoris. They rotate the femur laterally at the hip joint. On the outer thigh, the tensor fasciae latae sits in the fascia lata, a dense connective tissue layer that surrounds the thigh, and helps form the iliotibial tract with its tendons and the gluteus maximus.

The medial thigh also contains important muscles. The adductor longus, adductor brevis, and adductor magnus start on the pubic bone and attach to the femur. They adduct the thigh, and they can rotate it both medially and laterally. The adductor longus also flexes the thigh, while the adductor magnus extends it. The pectineus also helps adduct and flex the femur at the hip joint.

Hip Muscles That Move the Thigh

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,...

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

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...
