Medial cutaneous nerves of arm and forearm
Two sensory branches of the medial cord that supply the skin on the medial side of the arm and forearm.
اہم نکات
- Both from the medial cord.
- Arm: T1 + intercostobrachial (T2).
- Medial forearm skin = C8–T1 dermatomes.
- Upper limb nerves: C4–T2 segments; lower limb: L2–S2.
- Ventral root: basal-lamina neurons. Dorsal root: neural-crest ganglion cells.
- Nerve: epineurium → perineurium (blood–nerve barrier) → endoneurium.
