Muscular Branches Of Ulnar

Sure. The muscular branches of the ulnar nerve are a variety of branches of the ulnar nerve. One supplies the flexor carpi ulnaris muscle (a superficial muscle of the anterior compartment of the forearm), while the other supplies the ulnar half of the flexor digitorum profundus muscle (a deep muscle of the anterior compartment of the forearm). The flexor carpi ulnaris muscle is a superficial muscle of the forearm that flexes the wrist and ulnar deviates the hand. It originates from the medial epicondyle of the humerus, the olecranon process of the ulna, and the posterior border of the ulna. It inserts onto the pisiform bone and the hook of the hamate bone. The ulnar nerve supplies motor innervation to the flexor carpi ulnaris muscle. The ulnar half of the flexor digitorum profundus muscle is a deep muscle of the forearm that flexes the distal phalanges of the ring and little fingers. It originates from the medial epicondyle of the humerus, the coronoid process of the ulna, and the interosseous membrane. It inserts onto the distal phalanges of the ring and little fingers. The ulnar nerve supplies motor innervation to the ulnar half of the flexor digitorum profundus muscle.

Ulnar

The brachial plexus is formed by the ventral rami of c5-c8-t1 spinal nerves, and lower and upper halves of c4 and t2 spinal nerves. the plexus extends toward the armpit. the ventral rami of c5 and c6 form upper trunk, the ventral ramus of c7 forms the middle trunk, and the ventral rami of c8 and t1 join to form the lower trunk of the brachial plexus. under the clavicle, the trunks reorganize to form cords (fasciculi) around the axillary artery (arteria axillaris). the lateral cord (fasciculus lateralis) is formed by the upper and middle trunk, all three trunks join to form the posterior cord (fasciculus posterior), the lower trunk continues to the medial trunk (fasciculus medialis). the nerves (containing motor and sensory fibers) to the shoulder and to the upper limb emerge from the brachial plexus.
