Physiology

Parasympathetic nerve fiber

A single isolated parasympathetic autonomic nerve fiber drawn in simple medical diagram style as a slender, smooth, threadlike cord in pale yellow, light tan, or soft golden yellow. The fiber is elongated and slightly curved or wavy, with sparse delicate branching along the trunk and fine terminal branches. The terminal portion ends in small rounded synaptic boutons or bulb-like swellings, giving a lightly branching autonomic neural strand appearance.
