Efferent neurons carry information:

Efferent neurons carry information:

• A. From sensory receptors to the CNS
• B. From the CNS to muscles
• C. Between different neurons in the brain
• D. From muscles to sensory receptors

Answer: (B)

Efferent neurons carry information away from the central nervous system to effectors such as muscles or glands. That means signals travel from the CNS to the muscles to trigger movement or other responses. The other directions describe different neuron roles: sensory (afferent) neurons carry information from sensory receptors to the CNS, interneurons connect neurons within the CNS, and moving from muscles to sensory receptors isn’t the standard efferent pathway. For example, when you decide to move your hand, motor neurons (an efferent pathway) send signals from the brain/spinal cord to the arm muscles to produce the movement.
