B. Motor
C. Interneuron
D. Leukocyte



Answer :

Final answer:

Motor neurons are responsible for carrying signals from the brain to muscles to initiate movement.


Explanation:

Motor neurons are the cells at work when a signal from the brain is sent to the muscles to initiate movement. Motor neurons are responsible for carrying signals from the central nervous system to muscles, resulting in actions like running.

Motor neurons play a crucial role in the nervous system by transmitting signals that lead to muscle contractions. They work in coordination with sensory neurons which carry information to the brain from the environment.

Motor neurons are essential for enabling voluntary movements and are part of the pathway that starts with a decision in the brain, travels through the spinal cord, and ends with muscle contraction.
