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

Answer 1

Answer: The correct pathway for information in the nervous system is as follows-

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

When body is exposed to low temperatures ( that act as a stimuli), skin becomes cold that is sensed by the sensory receptors present on the skin. These receptors will carry the information to the brain via inter- neuron in the form of nerve impulses.

Brain processes the information and quickly produces desirable response ( in the form of shivering of body) and send it through motor neuron to the area of reception of stimuli ( that is skin).

Thus, last pathway correctly depicts the pathway for information in the nervous system.

Answer 2

Cold skin → sensory neuron → interneuron → motor neuron → shivering
