Anatomy

Trigeminal nerve

Large pale yellow cranial nerve, shown as a thick robust proximal root emerging from the side of the brainstem and expanding into a slightly bulbous ganglion-like region before dividing into three major distal branches. The overall form is fan-like or trident-like, with the three smooth cord-like cylindrical divisions radiating from a common origin. Each branch is rounded, gently curved, slightly tapering toward the ends. The central root is broader and thicker than the distal branches, emphasizing the characteristic three-part branching pattern.
