Verified step by step guidance

Step 1: Understand the classification of neurons based on their function. Neurons are categorized into three main types: sensory (afferent), interneurons, and motor (efferent).

Step 2: Recall that sensory (afferent) neurons carry signals from sensory receptors to the central nervous system (CNS). They are responsible for detecting stimuli such as touch, temperature, and pain.

Step 3: Interneurons are located within the CNS and act as connectors or integrators between sensory and motor neurons. They process information and determine the appropriate response.

Step 4: Motor neurons, also known as efferent neurons, transmit signals from the CNS to effectors such as muscles or glands, enabling movement or secretion. This is the classification of a motor neuron.

Step 5: Based on the definitions above, motor neurons are classified as efferent neurons because they carry signals away from the CNS to execute actions.
