Question

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

shivering → motor neuron → interneuron → sensory neuron → cold skin
interneuron → sensory neuron → motor neuron → shivering → cold skin
sensory neuron → cold skin → interneuron → motor neuron → shivering
cold skin → sensory neuron → interneuron → motor neuron → shivering

Answer 1

cold skin → sensory neuron → interneuron → motor neuron → shivering

Explanation: Cold is the stimulus detected by receptors in the skin (sensory neuron/afferent), the signal is processed by interneurons in the CNS, then a motor neuron (efferent) carries the command to muscles, producing shivering.
