What are the three types of neurons?

• A. Sensory, motor, and epineural
• B. Sensory, motor, and interneurons
• C. Efferent, afferent, and associative
• D. Motor, sensory, and multipolar

Answer: (B)

The three types of neurons are classified based on their functions in the nervous system: sensory neurons, motor neurons, and interneurons.

Sensory neurons are responsible for transmitting sensory information from receptors in the body to the central nervous system, enabling the brain to process sensory stimuli like touch, taste, sight, and sound.

Motor neurons carry signals from the central nervous system to muscles and glands, facilitating movement and physiological responses.

Interneurons serve as connectors between sensory and motor neurons within the central nervous system, playing critical roles in processing information and reflexes.

This categorization helps in understanding not just the pathways of signal transmission but also the complex interactions that occur within the nervous system. Each type of neuron has a distinct role that contributes to overall bodily function, making this classification fundamental to neuroscience and physiology.
