What type of nerves are responsible for carrying impulses from the brain to the muscles?

Motor nerves are responsible for transmitting impulses from the brain to the muscles. These nerves play a critical role in the somatic nervous system, which controls voluntary movements by sending signals to skeletal muscles, prompting them to contract and perform tasks. Through this process, motor nerves enable actions such as walking, talking, and other deliberate movements.

The other types of nerves mentioned serve different functions. Sensory nerves are responsible for carrying information from sensory receptors (like those in the skin, eyes, and ears) back to the brain, allowing us to perceive the environment. Autonomic nerves regulate involuntary bodily functions, such as heart rate and digestion, without conscious control. Interneurons function primarily within the central nervous system, facilitating communication between sensory and motor nerves, but they do not directly carry impulses to muscles. Thus, motor nerves specifically focus on muscle control and movement initiation.
