Synarthrotic
A type of joint that allows little to no movement.
Amphiarthrotic
A type of joint that allows slight movement.
Diarthrotic
A type of joint that allows free or full movement.
Fibrous Joints
Joints connected by collagen fibers typically allowing no movement.
Cartilaginous Joints
Joints connected by cartilage, allowing slight movement.
Synovial Joints
Joints characterized by a joint capsule, cartilage, and synovial fluid that allow free movement.
Hyaline Cartilage
The type of cartilage that is smooth and covers the ends of bones in synovial joints.
Fibrocartilage
Denser, stronger cartilage found in joints that require more stability, such as the menisci and labrum.
Articular Disc
A disc of fibrocartilage found in some synovial joints that improves stability and reduces friction.
Meniscus
Crescent-shaped fibrocartilage discs in the knee that provide cushioning and stability.
Labrum
A rim of fibrocartilage that deepens the socket in the shoulder and hip joints.
Bursa
Fluid-filled sacs that cushion tendons and reduce friction where they cross bones.
Tendon Sheath
A tube-like structure that surrounds tendons, providing lubrication and reducing friction.
Condylar Joint
A joint where the convex surface of one bone fits into the concave surface of another, allowing movement in two planes.
Pivot Joint
A joint that allows for rotational movement around a single axis, such as at the neck.
Hinge Joint
A joint that allows movement in one plane, like an elbow or knee.
Ball and Socket Joint
A joint where a spherical head of one bone fits into a cup-like socket of another bone, allowing multi-directional movement.
Synostosis
A bony joint formed by the fusion of two bones, offering no movement.
Osteoarthritis
A degenerative joint disease characterized by the loss of hyaline cartilage, commonly leading to stiffness and pain.
Rheumatoid Arthritis
An autoimmune inflammatory disorder that affects joints, causing pain, swelling, and potential joint deformation.
