Proper Palmar Digital Branches Of Median

Nerve system:

Spinal

Description:

The proper palmar digital branches of the median nerve are five nerves that supply sensation to the skin on the palmar surface of the fingers. They arise from the median nerve in the palm of the hand, just distal to the transverse carpal ligament. The proper palmar digital branches of the median nerve are named for the fingers that they supply. The first proper palmar digital nerve of the median nerve supplies sensation to the radial side of the thumb. The second proper palmar digital nerve of the median nerve supplies sensation to the radial side of the index finger. The third proper palmar digital nerve of the median nerve supplies sensation to the ulnar side of the index finger and the radial side of the middle finger. The fourth proper palmar digital nerve of the median nerve supplies sensation to the ulnar side of the middle finger. The fifth proper palmar digital nerve of the median nerve supplies sensation to the ulnar side of the ring finger.

Nerve Branched From:

Median

Parent Branch Plexus:

Brachial Plexus

Description:

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.
