Question

A dog starts chasing Gretchen. When her brain sends a signal to her muscles to run, which neurons are at work?

Answer 1

Answer: The correct answer is -

motor neurons.

Explanation:

Nervous system ( that includes two branches that are central nervous system and peripheral nervous system) helps in the transfer of nerve impulses to and from the various parts of body.

Sensory neurons receive information from sensory receptors (which are stimulated through outside environment). They take this information to the CNS (central nervous system that includes brain and spinal cord), where it gets processed and interpreted (particularly in the brain).

Ultimately, Motor neurons transfers this interpreted information (from the CNS to the muscles) to the glands, muscles or various other body organs for proper action to take place.

Therefore, motor neurons carry information from the CNS to dog muscles, which alarm him to run away.

Thus, motor neurons are at work.
