Which neuron causes a reaction by receiving impulse to produce movement?

Which neuron causes a reaction by receiving impulse to produce movement?

• A. Sensory
• B. Interneuron/Connecting
• C. Motor
• D. Peripheral Nerves

Answer: (C)

Movement is produced when a motor neuron carries the instruction from the central nervous system to a muscle. These neurons originate in the brain or spinal cord and their axons extend to muscles; when they fire, they release signals at the neuromuscular junction that cause muscle fibers to contract. Sensory neurons, on the other hand, detect stimuli and send impulses toward the CNS, not to muscles to make them move. Interneurons reside within the CNS and help process information to determine the appropriate response. Peripheral nerves are bundles that carry both sensory and motor fibers, but they are not the neuron type that directly triggers movement. So the neuron that directly causes a reaction leading to movement is the motor neuron.
