The Nervous and Endocrine Systems

Question 9 • Science 7 B (M12 25/26 S2)

Reese senses information from her hand, processes it, and determines that she needs to move her hand out of the way. Which is the path of information through the nervous system?

Answer
A
CNS → PNS → PNS
B
PNS → CNS → PNS
C
CNS → PNS → CNS
D
PNS → CNS → CNS

Explanation

Sensory information from Reese’s hand travels through the peripheral nervous system (PNS) to the central nervous system (CNS), where it is processed. The CNS then sends a movement command back through the PNS to her hand. So the path is PNS → CNS → PNS, choice B.
