The median nerve primarily supplies the arm and hand. It is one of the major peripheral nerves in the upper extremity and plays a crucial role in both motor and sensory functions. The median nerve innervates most of the flexor muscles in the forearm, which are essential for movements involving flexion of the wrist and fingers. Additionally, it provides sensory innervation to parts of the hand, particularly the lateral aspect, including the thumb, index, middle finger, and part of the ring finger.

Understanding the significance of the median nerve is vital, especially in the field of esthetics, as various treatments may involve manipulation or assessment of the upper extremities. Recognizing that the median nerve is not associated with the legs, feet, face, neck, trunk, or abdomen helps clarify its specific function and anatomical relevance. This distinction is important for professionals in esthetics to ensure safe and effective practice when working with clients.
