Joints

Suture joints

Found between the bones of the skull.

Syndesmosis joints

Found between the tibia and fibula.

Gomphosis joints

Found between your teeth and their sockets.

Synchondrosis joints

Found at epiphyseal growth plates and between the first rib and sternum.

Symphysis joints

Found between vertebral bodies (intervertebral discs) and at the pubic symphysis.

Ball-and-socket joints

Found in the shoulder and hip.

Hinge joints

Found in the elbow, knee, fingers, and toes.

Pivot joints

Found between C1 and C2 in the neck and between the radius and ulna.

Condyloid joints

Found in the knuckles and wrist.

Saddle joints

Found at the base of the thumb.

Plane (gliding) joints

Found between carpal bones in the wrist, tarsal bones in the foot, and vertebral articular processes.

Synarthrosis

An immovable joint.

Amphiarthrosis

A slightly movable joint.

Diarthrosis

A freely movable joint.

Movement of a ball-and-socket joint

Allows movement in all directions, including rotation.

Movement of a hinge joint

Allows bending and straightening (flexion and extension).

Movement of a pivot joint

Allows rotation.

Movement of a condyloid joint

Allows back-and-forth and side-to-side movement.

Movement of a saddle joint

Movement of a plane joint

Allows sliding or gliding.

3 structural classifications of joints

Fibrous, cartilaginous, and synovial.

Connection in fibrous joints

Connected by dense fibrous connective tissue.

Connection in cartilaginous joints

Connected by cartilage.

Synovial joints' uniqueness

They have a fluid-filled joint cavity and allow free movement.

Cartilage in synchondrosis joints

Hyaline cartilage.

Cartilage in symphysis joints

Fibrocartilage.

Functional classification of synovial joints

Functional classification of skull sutures

Synarthrosis.

Functional classification of intervertebral symphysis joints

Amphiarthrosis.

Functional classification of gomphosis joints
