In terms of neuronal signals, what does 'efferent' refer to?

The term 'efferent' in the context of neuronal signals refers specifically to signals that are sent away from the central nervous system to target organs or muscles. These signals are responsible for transmitting commands to stimulate actions, such as muscle contractions or glandular secretions. In the nervous system, efferent neurons are crucial for carrying out the responses that result from processed information.

While 'carries signals' mentions the transportation of signals, which is somewhat related, it lacks the specificity of the action being performed, namely the act of sending commands to effect change in the body. Therefore, 'sends signals' is the most precise choice, accurately reflecting the role of efferent neurons in conveying information from the brain and spinal cord to different parts of the body.
