The median nerve assists in the innervation of the elbow joint and gives muscular branches to pronator teres, flexor carpi radialis, palmaris longus, and flexor digitorum superficialis. The median nerve also has an anterior interosseous branch that innervates the lateral part of the flexor digitorum profundus, flexor pollicis longus, and pronator quadratus.

The ulnar nerve does NOT do which of the following?
The ulnar nerve gives rise to articular branches that innervate the elbow joint and muscular branches that innervate the flexor carpi ulnaris and medial half of the flexor digitorum profundus. The palmar cutaneous branch innervates the skin of the medial part of the palm, and the dorsal cutaneous branch innervates the posterior surface of the medial part of the hand and digits. The deep branch innervates the hypothenar muscles, adductor pollicis, interossei, and the 3rd and 4th lumbricals.
The radial nerve does NOT do which of the following?
The radial nerve gives a superficial branch that innervates skin on the dorsum of the hand. The radial nerve itself innervates the brachioradialis and extensor carpi radialis longus. It then gives a deep branch that innervates the extensor carpi radialis brevis and the supinator before continuing as the posterior interosseous nerve, which innervates the extensor digitorum, extensor digiti minimi, extensor carpi ulnaris, abductor pollicis longus, extensor pollicis brevis, extensor pollicis longus, and extensor indicis
Which of the following is NOT true in respect to the flexor pollicis brevis?
The flexor pollicis brevis is located medial to the abductor pollicis brevis. It flexes the thumb at the carpometacarpal and metacarpophalangeal joints and assists in opposition. Its tendon typically contains a sesamoid bone. It is innervated by the recurrent branch of the median nerve (C8–T1)
Which of the following is true in respect to the palmaris brevis?
The palmaris brevis, innervated by the ulnar nerve, wrinkles the skin of the hypothenar eminence and deepens the hollow of the palm, assisting the palmar grip. The muscle actually covers and protects the ulnar artery and the ulnar nerve, which innervates it. The muscle is not by definition in the hypothenar compartment. The palmaris longus, on the other hand, flexes the hand at the wrist and tightens the palmar aponeurosis.
The recurrent branch of the median nerve does NOT innervate which of the following?
The recurrent branch of the median nerve innervates the abductor pollicis brevis, flexor pollicis brevis, and opponens pollicis, but the deep branch of the ulnar nerve innervates adductor pollicis

The sternoclavicular joint . . .
The sternoclavicular joint, which does not dislocate easily, is a saddle-type synovial joint but functions as a ball-and-socket joint. It is the articulation of the sternal end of the clavicle with the manubrium of the sternum. The joint is supplied by the internal thoracic and suprascapular arteries and is innervated by branches of the medial supraclavicular nerve and the nerve to the subclavius
Which of the following is true in respect to the acromioclavicular joint?
The acromioclavicular joint is a plane-type synovial joint and is strengthened by the AC ligament and the coracoclavicular ligament, which is composed of the conoid and trapezoid ligaments. It is supplied by the suprascapular and thoracoacromial arteries and is innervated by the supraclavicular, lateral pectoral, and axillary nerves. When dislocated, it is referred to as a “separated shoulder”

In respect to movement of the arm at the glenohumeral joint, which of the following movements is correctly paired with its prime mover?

The deltoid (as a whole, but especially the central part) causes abduction, whereas the pectoralis major and latissimus dorsi cause adduction. The subscapularis causes medial rotation, whereas the infraspinatus causes lateral rotation

The elbow is a hinge type of synovial joint, strengthened by radial and ulnar collateral ligaments. It is supplied by arteries derived from the anastomosis around the elbow and is innervated by the musculocutaneous, radial, and ulnar nerves. It is surrounded by the intratendinous olecranon bursa, the subtendinous olecranon bursa, and the subcutaneous olecranon bursa
Which of the following joints is paired correctly with its type?
The proximal and distal radioulnar joints are pivot-type synovial joints. The radiocarpal (wrist) joint is a condyloid type of synovial joint. Intercarpal joints are plane-type synovial joints. Metacarpophalangeal joints are condyloid types of synovial joints. Interphalangeal joints are hinge-type synovial joints
All carpometacarpal and intermetacarpal joints are plane types of synovial joints EXCEPT for
All carpometacarpal and intermetacarpal joints are the plane-type synovial joints except for the carpometacarpal joint of the thumb, which is a saddle joint
