Which type of neuron carries impulses towards the Central Nervous System (CNS)?

Afferent neurons are responsible for transmitting sensory signals toward the Central Nervous System (CNS). These neurons carry information from sensory receptors located throughout the body, such as in the skin, muscles, and organs, to the brain and spinal cord where it can be processed.

This is a critical function in the nervous system as it allows for the interpretation of sensory input, which is essential for responding to environmental stimuli. In contrast, efferent neurons send impulses away from the CNS to muscles and glands, motor neurons specifically control muscle movement, and interneurons function as connectors that communicate between sensory and motor neurons within the CNS. Each type of neuron plays a distinct yet interconnected role in the functioning of the nervous system, emphasizing the importance of the afferent pathway in initiating the processing of sensory data.
