The Skeletal System- Articulations- ball-and-socket joint, ellipsoidal joint, gliding joint

Gliding joint:

A gliding joint allows only slight sliding movement.

What is a joint?

A joint is where two bones meet and articulate.

What are examples of ball-and-socket joints?

Examples of ball-and-socket joints include the shoulder joint and the hip joint.

What are examples of gliding joints?

Examples of gliding joint include those found in the carpal bones of the wrist and the tarsal bones of the ankle.

Are all joints movable?

Not all joints are mobile-- there is no movement at the sutures of the skull, and only limited movement occurs in joints such as the symphysis pubis.

What is the most mobile joints?

The most mobile joints are the synovial joints, found in the appendicular skeleton.

What releases synovial fluid?

The synovial membrane releases synovial fluid, which lubricates the joint and reduces friction.

Ball-and-socket joint:

This is the most mobile joint type in the body, and gives the greatest freedom of movement.

What is another name for ellipsoidal joints?

Another name for ellipsoidal joint is the condyloid joint.

What are the different synovial joint types?

The different synovial joint types include: ball and socket, ellipsoidal (condyloid), gliding (plane), hinge, pivot, and saddle.

Ellipsoidal joint:

This joint structure allows movement in two directions, such as that which takes place between the distal surfaces of the forearm bones (radius and ulna) and the adjacent carpal bones.

What does articulate mean?

To form a joint.

symphysis

a place where two bones are closely joined either forming an immovable joint or completely fused.
