The cell bodies in parasympathetic ganglia are primarily of which neuronal type?

• A. Unipolar
• B. Bipolar
• C. Pseudounipolar
• D. Multipolar

Answer: (D)

Multipolar neurons. Postganglionic neurons in parasympathetic ganglia have multiple dendrites and a single axon, which is the typical arrangement for autonomic motor neurons that integrate inputs from several preganglionic fibers and deliver signals to target organs. In contrast, unipolar (pseudounipolar) and bipolar shapes are characteristic of many sensory neurons, such as those in dorsal root or cranial sensory ganglia, not the autonomic postganglionic cells.
