The human nervous system is made of a huge number of interconnected neurons. The two main divisions of the nervous system are th

e central nervous system (CNS) and the peripheral nervous system (PNS). Which describes a common pathway of nerve impulses through the divisions of the nervous system?
A. CNS → sensory neurons of the PNS → motor neurons of the PNS

B. sensory neurons of the PNS → CNS → motor neurons of the PNS

C. sensory neurons of the PNS → motor neurons of the PNS → CNS

D. motor neurons of the PNS → CNS → sensory neurons of the PNS

Answer:

The correct answer is: B. sensory neurons of the PNS → CNS → motor neurons of the PNS.

Explanation:

The nervous system is the one in charge of receiving information, processing it, and generating the proper response to the stimulus.

The common pathway of nerve impulses would be: the receptors receive a stimulus, this information is taken to the CNS (Central Nervous System) thanks to the sensory neurons of the PNS (Peripheral Nervous System). In the CNS, the information is processed, and the response is transmitted through the motor neurons of the PNS, so it can reach the organs or muscles that can perform the wanted response.
