Sensory innervations in the hand MEDizzy
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.

The nerve supply to the upper limb is almost entirely supplied by the brachial plexus , a complex intercommunicating network of nerves formed in the neck by spinal nerve roots C5, C6, C7, C8 and T1.

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).
