The sensory innervation of the dorsum of the hand was variable. The most common pattern was being supplied by the SBRN innervating the lateral dorsal skin and the skin covering the lateral 2ยฝ digits and the DBUN innervating the medial dorsal skin and the skin covering the medial 1ยฝ digits found in 37.3%. All radial supply to the dorsum of the.
Cutaneous innervation of hand;
Anatomical Course. The ulnar nerve arises from the brachial plexus within the axilla region. It is a continuation of the medial cord and contains fibres from spinal roots C8 and T1. After arising from the brachial plexus, the ulnar nerve descends in a plane between the axillary artery (lateral) and the axillary vein (medial).

Cutaneous innervation of the upper limbs is the nerve supply to areas of the skin of the upper limbs (including the arm, forearm, and hand) which are supplied by specific cutaneous nerves . Modern texts are in agreement about which areas of the skin are served by which cutaneous nerves, but there are minor variations in some of the details.

Dermatomes are specific areas of the skin that receive sensory innervation from a single spinal nerve. Each spinal nerve emerges from the spinal cord and branches to different parts of the body, providing sensation and motor control. On the hand, dermatomes are particularly important for sensory perception, fine motor skills, and coordination.

Brachial plexus. The brachial plexus is a group of nerves that control the muscles of the shoulder, arm, forearm, and hand. These same nerves also provide sensations (feeling) of the whole upper limb. There are five components of the brachial plexus: roots, trunks, divisions, cords, and branches.

It is a mixed nerve and provides motor innervation to various muscles of the forearm and hand as well as sensory supply to the skin of the hand. The ulnar nerve can broadly be described as the nerve of the hand, as it innervates the vast majority of the intrinsic hand muscles.
