Which part of the nervous system is responsible for transmitting impulses away from the central nervous system?

The part of the nervous system responsible for transmitting impulses away from the central nervous system is indeed the efferent nerves. Efferent nerves are part of the peripheral nervous system and serve to carry motor commands from the brain and spinal cord to the muscles and glands of the body. This transmission allows for movement and responses to stimuli, making them crucial for action.

In contrast, afferent nerves carry sensory information towards the central nervous system, which is why they do not fit the description of transmitting impulses away. Interneurons are primarily involved in connecting sensory and motor neurons within the central nervous system, facilitating communication among them, but they do not directly carry impulses away from it. Sensory nerves, similarly, are responsible for conveying sensory information from the body to the central nervous system rather than transmitting impulses outward. Therefore, the role of efferent nerves as transmitters of impulses away from the central nervous system is what makes this choice the correct answer.
