Verified step by step guidance1
Step 1: Understand the question by identifying the three main types of neurons in the human nervous system. Neurons are specialized cells responsible for transmitting signals throughout the body.
Step 2: Recall the functional classification of neurons. The three main types are sensory neurons, motor neurons, and interneurons. Each type has a distinct role in the nervous system.
Step 3: Sensory neurons (also called afferent neurons) are responsible for transmitting signals from sensory receptors to the central nervous system (CNS).
Step 4: Motor neurons (also called efferent neurons) carry signals from the CNS to muscles or glands, enabling movement or secretion.
Step 5: Interneurons act as connectors within the CNS, processing information and facilitating communication between sensory and motor neurons.
