Question

question 4 of 10
which type of neuron sends a signal from the gray matter of the spinal cord to a muscle or gland?

afferent neuron
sensory neuron
efferent neuron
interneuron

Explanation:

• Afferent (sensory) neurons carry signals to the CNS (spinal cord/brain), not from spinal cord to muscles/glands.
• Sensory neurons are a type of afferent neuron, so they also don't send signals from spinal cord to effectors.
• Efferent neurons (motor neurons) transmit signals from the CNS (spinal cord’s gray matter) to muscles or glands (effectors) to initiate responses.
• Interneurons connect neurons within the CNS and don't send signals to muscles/glands.

Answer:

C. Efferent neuron
