Question

In contrast to the somatic nervous system, the autonomic nervous system :

• A. Stimulates its effector cells
• B. Has two-neuron efferent pathway
• C. Has centers in the brain and spinal cord
• D. Has both afferent and efferent fibers

Answer 1

The correct option is B

Has two-neuron efferent pathway

The autonomic nervous system has a unique sequential two-neuron efferent pathway;

1. The preganglionic neuron arising at the spinal cord or at the cranial nerves synapses on a postganglionic neuron arising at a ganglion near the target organ.

2. The postganglionic neuron will then synapse at the target organ.
