Exam 6: The Elbow and Radioulnar Joints

The radial nerve innervates all of the following muscles except:

Lateral epicondylitis is a condition that occurs less commonly than medial epicondylitis.

Flexion of the elbow occurs in the _______ plane of motion, and supination of the forearm occurs in the _______ plane of motion.

The olecranon process is located on the medial aspect of the ulna.

Even though both radioulnar joints are freely moveable diarthrodial joints, the joint between the shafts of the two bones is referred to as being syndesmosis.

As the elbow reaches full extension, the olecranon process of the ulna is received by the olecranon fossa of the humerus, and this provides increased joint stability.

The elbow joint is a hinge-type joint that allows only internal and external rotation in the sagittal plane.

Which of the following muscles is involved in both pronation and supination?

The anterior interosseous nerve branching from the median nerve (C6, C7) innervates the _______.

Medial epicondylitis is frequently referred to as "golfer's elbow."

The posterior interosseous nerve branching from the radial nerve (C6) innervates the _______.

Radioulnar supination is performed by all of the following muscles except the:

The chief function of the _______ is to pull the synovial membrane of the elbow joint out of the way of the advancing olecranon process during extension of the elbow.

Which of the following is not an action of the brachioradialis muscle?

Which of the following statements is true about the carrying angle?

The insertion of the biceps brachii muscle is on the tuberosity of the radius and bicipital aponeurosis.

The pronator teres muscle is innervated by the median nerve (C6, C7).

Explain the mechanics of how both acute and chronic injuries occur to cause injury to the ulnar collateral ligament of the elbow.

Which of the following is a posterior muscle?

The ulna is much larger proximally than the radius.
