Anterior Forearm Flashcards
Ulna Olecranon Process Coronoid process
Tuberosity of ulna Styloid process (ulnar)
Radius Head of Radius Neck of Radius
Radial Tuberosity Styloid Process (radial)
Ulnar Nerve
What nerve is located deep to the flexor carpi ulnaris and innervates one and 1 1/2 muscles in the forearm – the flexor carpi ulnaris and the ulnar (medial half) of the flexor digitorum profundus?
Radial Nerve
What nerve divides into a superficial and deep branch immediately after piercing the lateral intermuscular septum? The superficial branch is sensory and continues distally beneath the brachioradialis muscle, while the deep branch of the radial nerve pierces the supinator muscle and supplies motor fibers to extensor muscles of the forearm (posterior forearm).
Median Nerve
What nerve supplies all of the flexors of the anterior forearm except for the Flexor Carpi Ulnaris and the ulnar half of the flexor digitorum profundus?
Brachioradialis Muscle
Flexor Retinaculum (transverse carpal ligament)
Carpal Tunnel
Pronator Teres Muscle
Flexor Carpi Radialis
Palmaris Longus
Flexor Digitorum Superficialis
Flexor Carpi Ulnaris
What are the superficial flexor muscles of the anterior forearm? The are all innervated by the median nerve except for the flexor carpi ulnaris (ulnar nerve)
Flexor Digitorum Profundus Muscle
Pronator Quadratus
What are the deep muscles of the anterior forearm? The medial nerve innervates the pronator quadratus and half of the flexor digitorum profundus, and the other half is innervated by the ulnar nerve.
Radial Artery
What artery is a branch off of the brachial artery that runs deep to the brachioradialis along with the superficial branch of the radial nerve?
Ulnar Artery
Common Interosseus Artery
Anterior and posterior interosseus arteries
What artery is a branch off of the brachial artery that passes posteriorly to go deep to the superficail muscles of the forearm? It passes between the flexor digitorum superficialis and flexor digitorum profundus.
What Is a branch off of the ulnar artery that divides into an anterior and posterior interosseous artery?
What artery passes above the interosseous membrane to supply blood to the posterior compartment (extensor compartment) of the forearm?
What artery joins the anterior interosseous nerve and passes distally between the flexor digitorum profundus and the flexor pollicis longus?
