Exam 7: The Wrist and Hand Joints

Disruption of a tendon at or near the insertion of the ________ is known as a jersey or sweater finger and should be addressed surgically within approximately one week.

Movements of the wrist joint include flexion, extension, abduction, and adduction.

The ulnar nerve provides sensation to the ulnar side of the hand, the ulnar half of the ring finger, and the entire little finger.

Which of the following is the origin of the flexor digitorum profundus muscle?

Which of the following muscles performs actions in the frontal plane about the sagittal axis?

Which of the following is the origin of the flexor carpi radialis muscle?

Which of the following is the primary function of the extensor pollicis longus muscle?

Which of the following muscles may not be palpated on the dorsal aspect of the hand?

Which of the following muscles performs extension of the index finger at the metacarpophalangeal joint?

Carpal tunnel syndrome is a condition in which there is an increased pressure in the carpal tunnel, which interferes with the normal function of the median nerve.

Each finger has three interphalangeal joints, whereas the thumb has only two.

The muscles of the wrist and hand are all innervated from the radial and median nerves and their respective branches.

Which of the following muscles performs adduction of the wrist?

All of the flexor tendons except for the flexor carpi ulnaris and palmaris longus pass through the carpal tunnel, along with the median nerve.

Which of these muscles may be palpated just proximal to the dorsal aspect of the wrist and approximately 1 cm medial to the radial styloid?

Which of the following is the insertion of the extensor carpi radialis longus muscle?

Which of the following is the only muscle that flexes the finger distal interphalangeal joint (DIP) joints?

The extensor carpi radialis longus muscle can perform weak extension of the elbow during a concentric contraction.

The wrist flexor muscles have their origin on the medial epicondyle of the humerus.

Which of the following muscles performs flexion of the thumb?
