Verified step by step guidance

Step 1: Understand the role of neurons in the nervous system. Neurons are specialized cells that transmit signals throughout the body. They can be classified based on their function: sensory (afferent) neurons, interneurons, and motor (efferent) neurons.

Step 2: Review the function of sensory (afferent) neurons. These neurons are responsible for transmitting sensory information from the body to the central nervous system (CNS). They do not directly initiate muscle contraction or activate glands.

Step 3: Examine the role of interneurons. Interneurons are located within the CNS and act as connectors between sensory and motor neurons. They process information but do not directly initiate muscle contraction or activate glands.

Step 4: Focus on motor (efferent) neurons. These neurons transmit signals from the CNS to muscles and glands, causing them to contract or activate. This classification of neurons is directly responsible for initiating muscle contraction and activating glands.

Step 5: Eliminate glial cells as an option. Glial cells are supportive cells in the nervous system that provide structural and functional support to neurons but do not transmit signals or initiate muscle contraction or gland activation.
