Anatomy

Sciatic nerve

A very large pale yellow peripheral nerve trunk depicted as the largest major limb nerve, shown as a thick broad cord with a slightly flattened cylindrical form and smooth outer sheath. The surface has subtle longitudinal fascicular or bundled fiber texture with faint striations and a slightly glossy appearance. It descends as a long robust gently curving trunk from the lower spine through the buttock into the posterior thigh with minimal proximal branching, then tapers slightly distally and divides near its lower end into two major terminal branches.
