Medial cutaneous nerve of forearm

Medial Cutaneous Nerve of Forearm (also known as the Anterior Cutaneous Nerve of Forearm or Nervus Cutaneus Antebrachii Medialis in Latin) is a nerve in the human body that provides sensation to the skin of the forearm.

Etymology

The term "Medial Cutaneous Nerve of Forearm" is derived from the Latin words 'Medialis' meaning 'middle', 'Cutaneus' meaning 'skin', 'Antebrachii' meaning 'forearm', and 'Nervus' meaning 'nerve'.

Anatomy

The Medial Cutaneous Nerve of Forearm is a branch of the Median Nerve, which is one of the main nerves of the upper limb. It originates from the Brachial Plexus, a network of nerves located in the neck and axilla.

The nerve travels down the arm, passing through the Cubital Fossa (the area in front of the elbow), before dividing into anterior and posterior branches. The anterior branch supplies the skin of the medial (inner) side of the forearm, while the posterior branch supplies the skin of the ulnar (outer) side of the forearm.

Clinical Significance

Damage to the Medial Cutaneous Nerve of Forearm can result in loss of sensation in the areas of the skin it supplies. This can occur due to trauma, compression, or diseases affecting the nerves such as Peripheral Neuropathy.
