Synarthrosis

A type of joint that allows little or no movement, such as sutures in the skull.

Cartilaginous Joint

A type of joint where cartilage connects bones, allowing limited movement.

Synovial Joint

A joint characterized by a joint cavity filled with synovial fluid, allowing for free movement.

Articular cartilage

Smooth, white tissue that covers the ends of bones where they come together to form joints.

Synovial fluid

A viscous fluid found in the cavities of synovial joints, providing lubrication.

Ligament

A fibrous connective tissue that connects bones to other bones.

Intracapsular Ligament

A ligament located inside the joint capsule.

Extracapsular Ligament

A ligament located outside the joint capsule.

Bursa

A fluid-filled sac that provides cushioning between bones and tendons or muscles.

Meniscus

A crescent-shaped cartilage that provides cushioning and stability in certain joints, such as the knee.

Fibrous Joint

A type of joint connected by dense connective tissue, allowing little to no movement.

Hinge Joint

A type of synovial joint that allows movement primarily in one plane, like the elbow.

Pivot Joint

A joint that allows rotational movement around a single axis.

Condylar Joint

A joint that allows movement in two planes, such as the knuckles.

Ball and Socket Joint

A joint that allows for rotational movement and has the greatest range of motion, like the shoulder.

Flexion

A movement that decreases the angle between two parts.

Extension

A movement that increases the angle between two parts.

Abduction

Movement away from the midline of the body.

Adduction

Movement toward the midline of the body.

Rotator Cuff

A group of muscles and their tendons that act to stabilize the shoulder.

Glenoid Labrum

A fibrocartilaginous structure that deepens the glenoid cavity, increasing stability in the shoulder joint.
