Structural Classification of Joints

Joints can be structurally classified into fibrous, cartilaginous, and synovial joints based on the type of associated connective tissue and the presence of a synovial cavity between the articulating bones.
Fibrous joints are connected by dense irregular connective tissue composed of collagen fibers.
Fibrous joints fixed by short tissue fibers are not movable&#8212;for example, sutures present between the skull bones. In comparison, fibrous joints connected with long tissue fibers are slightly movable&#8212;for example, the joint between the shafts of the radius and ulna.
Cartilaginous joints are connected by cartilaginous connective tissues, such as hyaline cartilage and fibrocartilage.
The joints fixed by hyaline cartilage are mostly immovable&#8212;for example, the first sternocostal joint. The joints with fibrocartilage discs are slightly movable&#8212;for example, the intervertebral joints.
Synovial joints have a fluid-filled cavity with articulating bone surfaces covered by articular cartilage and the joint is surrounded by fibrous connective tissue. These joints are freely movable&#8212; for example, the knee joint.

structural classification of joints

Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective tissue. It lacks a synovial cavity. The bones are joined by dense irregular connective tissue rich in collagen fibers. These joints allow minimal to no movement.
At a cartilaginous joint, the bones are joined by hyaline cartilage or fibrocartilage. These joints also lack synovial cavities. These joints provide more stability than fibrous joints but allow limited movement.
At a synovial joint, the articulating surfaces of the bones are not directly connected but instead come into contact with each other within a joint cavity that is filled with lubricating fluid. They also contain dense irregular connective tissue in the articular capsule. Bones in a synovial joint are often stabilized and held together by accessory ligaments. Synovial joints allow for free movement between the bones and are the most common joints of the body.

types of body joints by movement

Body joints, or articulations, are grouped by how the bones are connected and how much they move. The main structural features are the tissue between the bones and whether a fluid-filled joint cavity is present. These differences divide joints into three structural classes.

Fibrous joints connect adjacent bones with fibrous connective tissue. They do not have a synovial cavity. The bones are joined by dense irregular connective tissue rich in collagen fibers, so movement is minimal to none.

Cartilaginous joints join bones with hyaline cartilage or fibrocartilage. They also lack synovial cavities. These joints give more stability than fibrous joints, but they still allow only limited movement.

Synovial joints are different because the bone surfaces are not directly connected. Instead, they meet inside a joint cavity filled with lubricating fluid. These joints also have dense irregular connective tissue in the articular capsule, and accessory ligaments often help hold the bones together. Synovial joints allow free movement and are the most common joints in the body.

Types of Body Joints by Movement

introduction to joints

Joints: Stability and Movement

Joints are where bones come together in the human body. The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Many joints let bones move smoothly against each other, while other joints are built for support and very little movement. Joint stability and movement are closely linked. Joints that are very stable usually allow little or no mobility. Joints that allow the most movement are the least stable. This...

functional classification of joints

Joint Mobility and Bone Movement

Joint mobility is the basis of the functional classification of joints. Joints are grouped by how much movement they allow between nearby bones. They are classified as synarthrosis, amphiarthrosis, or diarthrosis. A synarthrosis is an immobile or nearly immobile joint. These joints form a strong union between bones. That strength is important where the bones help protect internal organs. Examples include sutures between the bones of the skull, which protect the brain, and the manubriosternal...

structural joints: fibrous joints

Fibrous Joints in Skull, Teeth, and Limbs

Fibrous joints connect bones with fibrous connective tissue. They give the body stability and allow little to no movement between the bones that meet there. There are three kinds of fibrous joints: sutures, syndesmoses, and gomphoses. A suture joins the bones of the skull, except for the mandible. The strong fibrous tissue at these joints helps protect the brain and shape the face. In adults, the skull bones lie close together, and fibrous tissue fills the narrow space between them. Many...

structural joints: cartilaginous joints

Cartilage Joints in Bones and Growth

Cartilaginous joints are bone connections made with cartilage, a tough but flexible connective tissue. They do not have a joint cavity like synovial joints. Instead, the bones are linked by either hyaline cartilage or fibrocartilage. One type of cartilaginous joint is the synchondrosis, which means bones are joined by hyaline cartilage. A synchondrosis can be temporary or permanent. The temporary form is the epiphyseal, or growth, plate in a growing long bone. This plate is the growing hyaline...

structural joints: synovial joints

Synovial Joints: Mobility and Lubrication

Synovial joints are the body’s most mobile joints. They have a joint cavity, which is a fluid-filled space where the bones meet. Unlike fibrous or cartilaginous joints, the bone surfaces in a synovial joint are not directly joined by fibrous connective tissue or cartilage. This structure lets the bones move smoothly against each other. The walls of the joint cavity are made by the articular capsule, a fibrous connective tissue structure that attaches to each bone just outside the articulating...

articulations of the vertebral column

How Vertebrae and Joints Control Spine Motion

The vertebral column has synovial joints that help control how the spine moves. Adjacent vertebrae connect not only through the intervertebral discs, but also through joints between the superior and inferior articular processes. These joints are called zygapophysial joints, or facet joints, and they are plane joints that allow only limited motion. The direction of the articular processes changes in different regions of the spine. This change affects which movements are possible in each area.

knee joint

Knee Joint Ligaments and Menisci

The knee joint is the most complicated joint in the body. It includes three articulations: two tibiofemoral joints and one patellofemoral joint. As a synovial joint, it has a thin articular capsule that partly surrounds the joint cavity. Several ligaments, muscles, and cartilaginous structures help the knee move and stay stable. Seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris muscle group, is the main ligament that stabilizes the...

ankle joint

Ankle Hinge Motion and Ligaments

The ankle joint is a hinge joint that links the foot and lower leg. It is formed by the talocrural joint, which brings together the talus bone of the foot with the distal ends of the tibia and fibula in the leg. The talus has a square-shaped top surface with three areas of articulation. The upper part of the talus meets the inferior tibia and carries body weight between the leg and foot. The medial malleolus of the tibia and the lateral malleolus of the fibula hold the talus in place on the...

development of the limb synovial joints

How Limb Joints Form in the Embryo

Limb synovial joints form during embryonic development as the bones of the arms and legs begin to take shape. The process starts with mesenchyme, the embryonic tissue that gives rise to bones, cartilage, and connective tissues. Mesenchymal stem cells first become chondrocytes, which make hyaline cartilage. This cartilage later becomes the model for each bone and then turns into bone through endochondral ossification. The limbs first appear as small limb buds on the sides of the embryo near the...

Skeletal System

Content elaboration: The skeletal system is composed of bones, cartilage, joints and ligaments. Bones make up most of the skeleton. There are four main cell types that compose bone tissue, each with a specific function: osteogenic cells, osteocytes, osteoblasts and osteoclasts. The microscopic anatomy of compact bone includes osteons. Bones are classified by their shape. The structure of a typical long bone can be explored. Specific bones of the skeleton can be studied by their subdivisions: the axial skeleton and the appendicular skeleton. Cartilage is found in areas of the nose, ears, ribs and joints. Joints can be classified by structure or by function. The general structure of synovial joints may be explored. Ligaments connect bone to bone, stabilizing joints. The skeletal system provides support for the human body, protects soft organs, allows for movement due to attachment of muscles, stores minerals and fat and forms blood cells. Processes of the skeletal system include hematopoiesis, ossification and bone growth and remodeling. A comparison of male to female, juvenile to adult or human to other vertebrate skeletons may be explored. Homeostatic imbalances are explored. These include, but are not limited to, osteoporosis, malnutrition, fractures, anterior cruciate ligament (ACL) injuries and arthritis. Investigations are used to understand and explain the skeletal system in a variety of inquiry and design scenarios that can incorporate evolutionary concepts, scientific reasoning, comparative analysis, communication skills and real-world applications.

Muscular System

Content elaboration: The muscular system consists of three types of muscle cells: skeletal, smooth and cardiac. The primary function of the muscular system is to contract, thereby, moving the body and internal fluids, maintaining posture, generating heat and stabilizing joints. Muscles are controlled voluntarily and/or involuntarily. Heart muscle cells are mononucleated, branched and striated. Intercalated disks are characteristic of cardiac muscle and aid in communication between cardiac muscle cells. Smooth muscle cells, found in the hollow organs and blood vessels, are mononucleated, spindle-shaped and nonstriated. Skeletal muscle cells, found attached to bones and skin, are multinucleated, cylindrical and striated. The muscles of the body can be studied by group, which include the muscles of the head, face and neck, the trunk and the upper and lower limbs. Processes of the muscular system include gross body movements produced by skeletal muscles as they interact with the skeletal system, and muscle contraction. The connection between the nervous system and the skeletal system should be explored through the study of action potentials and the resulting contraction of sarcomeres, as described by the sliding filament theory. Energy processing and muscle responses to stimuli can be studied along with building muscle tissue through exercise. The effects of steroids can also be investigated. Homeostatic imbalances are explored. These include, but are not limited to, muscular dystrophy and atrophy. Investigations are used to understand and explain the muscular system in a variety of inquiry and design scenarios that can incorporate evolutionary concepts, scientific reasoning, comparative analysis, communication skills and real-world applications.
