Anatomy and Function of the Posterior Compartment of the Forearm Quiz

The radial artery supplies blood to the muscles in the posterior forearm compartment.

The annular ligament runs across the ulnar notch of the radius and stabilizes the distal radioulnar joint.

Extensor carpi ulnaris has its origin on the lateral epicondyle of the humerus in the posterior forearm compartment.

The radial nerve is responsible for the motor innervation of the extensor muscles in the posterior forearm compartment.

Extensor indicis is the muscle responsible for extending the index finger in the posterior forearm compartment.

Triceps brachii is the primary muscle responsible for elbow extension in the posterior forearm compartment.

The muscles in the posterior forearm compartment are innervated by the radial nerve.

Flexor carpi radialis is not a muscle in the posterior forearm compartment.

The extensor pollicis longus muscle is responsible for extending the thumb in the posterior forearm compartment.

Extensor digiti minimi is the muscle responsible for extending the little finger in the posterior forearm compartment.

The brachioradialis muscle's primary function is elbow flexion in the posterior forearm compartment.

Supinator is the primary muscle responsible for forearm supination in the posterior forearm compartment.

The space between the olecranon process and the posterior aspect of the humerus during flexion is known as the cubital tunnel.

The radial nerve provides sensory innervation to the skin over the dorsal aspect of the hand in the posterior forearm compartment.

The anconeus muscle's primary function is elbow extension in the posterior forearm compartment.

The superficial branch is not a branch of the radial nerve in the posterior forearm compartment.

The joint formed by the proximal ends of the radius and ulna is called the proximal radioulnar joint in the posterior forearm compartment.
