Question

Quizplus · Accepted Answer

The autonomic nervous system has a chain of two motor neurons, with one located in the central nervous system (CNS) and the other located outside the CNS, in a ganglion. This is in contrast to the somatic nervous system, which has a single motor neuron that extends from the CNS to the effector organ.

Answer: C 
 The autonomic nervous system is responsible for stimulating its effector cells, which are smooth muscle, cardiac muscle, and glands. This is in contrast to the somatic nervous system, which stimulates skeletal muscle.

Answer: D 
 The autonomic nervous system has both sensory and motor fibers, which allows it to receive information from the internal environment and initiate appropriate responses.

Answers B and E are incorrect. The autonomic nervous system does not have a chain of two sensory neurons, and it is not a subdivision of the central nervous system.
