Question

Autonomic preganglionic fibers arising from the midbrain, pons, and medulla oblongata are fibers of the _____ nervous system.

Answer 1

The autonomic preganglionic fibers arising from the midbrain, pons, and medulla oblongata are fibers of the preganglionic parasympathetic nervous system.

Step-by-step explanation:

The autonomic preganglionic fibers arising from the midbrain, pons, and medulla oblongata are fibers of the preganglionic parasympathetic nervous system. These fibers are responsible for transmitting signals from the central nervous system to autonomic ganglia, which then relay the message to target organs. In contrast, preganglionic sympathetic fibers originate from the thoracic and lumbar regions of the spinal cord.
