Classically, sensory innervation of the dorsal aspect of the hand is ensured by the superficial branch of the radial nerve (SBRN), the dorsal branch of the ulnar nerve (DBUN), and the lateral antebrachial cutaneous nerve (LABCN) [12, 17].
19 lip 2017 · The objective of the present review is to assemble the recognized anatomical variations, classifications, and clinical evidence with regard to innervation of the hand and discuss the clinical significance of these variations.
13 lis 2023 · The hand itself consists of specific bones onto which various muscles are attached, and a collection of neurovascular structures responsible for drainage and innervation. However, the intrinsic muscles of the hand are only partially responsible for all its range of motion.
The sheaths are tubular structures that surround part of the fingers. The tendons connect muscles in the arm or hand to the bone to allow movement. In addition, there are arteries, veins and nerves within the hand that provide blood flow and sensation to the hand and fingers.
Each dot in the drawings of the hand represents a single sensory unit innervating the skin area. Histograms give the density of innervation in the following three skin regions: the tip of the finger, the rest of the finger, and the palm.

1 cze 2004 · Mechanical coupling between neuromuscular compartments serving different fingers, short-term synchrony between motor units acting on different fingers, and the broader central coactivation of hand muscles all appear to limit independent action of the fingers.
Purpose: The objective of the present review is to assemble the recognized anatomical variations, classifications, and clinical evidence with regard to innervation of the hand and discuss the clinical significance of these variations.
