What is the primary function of sensory neurons in the body?

The primary function of sensory neurons is to process and transmit sensory information from the sensory receptors to the central nervous system (CNS). These neurons are specialized to respond to various stimuli, such as light, sound, touch, temperature, and chemical signals. When a sensory receptor detects a stimulus, it generates an electrical signal that travels along the sensory neuron to the brain or spinal cord, where the information is further processed and interpreted, allowing the organism to respond appropriately to its environment.

This function is essential because it enables organisms to perceive and interact with the world around them. If sensory neurons did not effectively transmit this information, individuals would struggle to interpret their surroundings, making tasks such as avoiding danger or enjoying pleasant experiences challenging.
