Nerves that carry impulses from the brain to the muscles are known as:

Motor nerves are responsible for transmitting impulses from the brain to the muscles, facilitating voluntary movements. These nerves are part of the peripheral nervous system and play a key role in the somatic nervous system, which controls activities of the body that are under conscious control. When the brain sends a signal to initiate movement, motor nerves carry that signal to the muscle fibers, prompting them to contract and produce movement.

In contrast, sensory nerves carry impulses from sensory receptors to the central nervous system, providing the brain with information about the environment and the body’s internal state. Interneurons are the connectors that facilitate communication between sensory and motor nerves within the central nervous system, but they do not directly carry impulses to muscles. Autonomic nerves regulate involuntary functions, such as heart rate and digestion, which are not related to muscular movement. Hence, motor nerves are the correct designation for those transmitting signals to muscles.
