Exam 10: A: Articulations

An articulation is a point of contact between bones.

During childbirth,the hyaline cartilage in the symphysis pubis allows for some slight movement.

Total hip replacement is the most common orthopedic operation performed on older persons in the United States.

Hyaline cartilage is associated only with synovial joints.

The intercarpal joints occur at the points of articulation between the bones of the ankle.

It is recommended that joint replacement surgery be done on younger people rather than older people because they are better able to tolerate the procedure.

A projection of one bone that articulates with a ring in another bone describes a condyloid joint.

Arthroplasty is the total or partial replacement of a joint with a prosthesis.

The "joints" between the epiphyses and diaphysis in a developing bone can be classified as synchondroses joints.

The occipital bone's joint with the atlas is an example of a condyloid joint.

The vertebral column contains both cartilaginous joints and synovial joints.

A joint must allow movement between two bones to be called a joint.

If you are standing up and looking straight up toward the sky,your cervical spine will be hyperextended.

A "pulled elbow" is more common in older adults because the disk-shaped head of the radius begins to erode away.

The glenoidal labrum is part of the hip joint that reinforces the acetabulum.

Fontanels become sutures.

Because hinge joints can be involved in both flexion and extension,they are considered biaxial joints.

Because of the instability of the glenoid cavity and humerus,one of the strongest ligaments in the body is found surrounding the shoulder.

The depth of the acetabulum gives stability to the hip joint.

The acetabulum is a deep,cuplike socket,whereas the glenoid cavity is shallow and saucer-shaped.
