Which type of neurons receive sensory information and send it to the CNS?

Afferent neurons, also known as sensory neurons, play a crucial role in the nervous system by receiving sensory information from the environment and transmitting it to the central nervous system (CNS). They are equipped with sensory receptors that detect stimuli such as light, sound, temperature, and pressure. Once they gather this sensory data, they convert it into electrical signals, which are then relayed to the CNS for processing. This enables the brain and spinal cord to interpret the signals and respond appropriately.

Understanding the function of afferent neurons is essential because they form the fundamental pathway for sensory experience and perception. The information they provide is critical for how organisms interact with their surroundings and make decisions based on sensory input. This is a foundational concept in neuroscience that underscores the significance of sensory input in shaping behavior and responses.
