A&P08 Joints of the Skeleton MC

A synarthrosis is a type of joint found

• in the arms and legs
• in the skull
• where the radius meets the humerus
• between the vertebrae

Both a gomphosis and a syndesmosis are types of

• slightly movable joints
• freely movable joints
• immovable joints
• disjoints

Where the two pubic bones come together, the joint that forms is

• amphiarthrotic
• diarthrotic
• gomphotic
• synarthrotic

A diarthrotic joint occurs at all the following locations except

• the knee
• the elbow
• the wrist
• the skull

The function of synovial fluid is to

• regulate calcium content at the joint
• lubricate a diarthrotic joint
• synthesize the proteins of ligaments
• manufacture red blood cells

An example of a hinged joint is found at the

• vertebral column
• junction of atlas and axis
• knee
• glenoid cavity

Where the concave surface of one bone fits the convex surface of another bone, the joint is know as a

• gliding joint
• ball-and-socket joint
• hinged joint
• saddle joint

When a joint moves and reduces the angle between two bones at the joint, the movement is called a

• protraction
• flexion
• pronation
• supination

Moving a body part away from the body's midline and back to the midline represents two movements known as

• pronation and supination
• elevationa nd depression
• abduction and adduction
• flexion and extension

Pronation is a joint movement in which

• the forearm is rotated so the palm is backward
• the forearm is rotated so the palm faces forward
• a body part such as the shoulders is raised
• a body part such as the shoulders is lowered
