Pectoral nerves

The lateral pectoral nerve (lateral cord) and medial pectoral nerve (medial cord) supply the pectoral muscles; they are named after the cords, not their position.

اہم نکات

• Lateral pectoral = lateral cord; medial pectoral = medial cord.
• Lateral pierces the clavipectoral fascia.
• Medial supplies pectoralis minor and major.
• 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.
• Cut nerve: Wallerian degeneration; regrows 0.5–3 mm/day.
