The Nervous and Endocrine Systems

Question 6 • Science 7 B (M12 25/26 S2)

When the body is exposed to low temperatures, which is the pathway for information in the nervous system?

Answer
A
shivering → motor neuron → interneuron → sensory neuron → cold skin
B
interneuron → sensory neuron → motor neuron → shivering → cold skin
C
sensory neuron → cold skin → interneuron → motor neuron → shivering
D
cold skin → sensory neuron → interneuron → motor neuron → shivering

Explanation

Cold receptors in the skin detect the low temperature and send information along a sensory neuron to the central nervous system. An interneuron relays the signal to a motor neuron, which activates the muscles to produce shivering. So the pathway is cold skin → sensory neuron → interneuron → motor neuron → shivering, choice D.
