Physiology

Autonomic nerve fiber

Thin, delicate, lightly curved unmyelinated autonomic nerve fiber shown as a pale yellow wavy axon-like strand, branching into fine threadlike processes. Multiple bead-like swellings are present along its length, with no thick myelin sheath and no large terminal bulb, suitable for spreading across smooth muscle surfaces.
