A sensory neuron is a type of nerve cell that is responsible for transmitting sensory information from the body's sensory receptors to the central nervous system. These neurons detect stimuli such as touch, temperature, pain, and taste, converting these signals into electrical impulses that can be processed by the brain. Sensory neurons play a crucial role in how we perceive our environment. They are part of the peripheral nervous system and work alongside other types of neurons, such as motor neurons and interneurons, to facilitate communication within the body. This process allows us to respond appropriately to various stimuli.
