Which type of neuron is responsible for transmitting impulses from sensory receptors to the CNS?

Sensory neurons are specifically designed to carry signals from sensory receptors to the central nervous system (CNS). These neurons detect various stimuli such as light, sound, touch, taste, and smell, and convert these stimuli into electrical impulses. This process is crucial for the body to respond appropriately to the environment.

By relaying information from the peripheral sensory receptors, sensory neurons play a vital role in our perception of the world and in initiating the body's responses to environmental changes. Their axons extend from the receptor sites in the periphery to the spinal cord or brain, ensuring that sensory information reaches the CNS for processing.

Motor neurons and interneurons serve different functions; motor neurons transmit impulses away from the CNS to effectors (like muscles and glands), and interneurons connect sensory and motor neurons within the CNS to facilitate communication and processing. Reflex neurons are not a classified type of neuron; reflex actions involve a pathway that includes sensory neurons, interneurons, and motor neurons but don't denote a specific neuron type. This distinction highlights the unique role of sensory neurons in the nervous system's operation.
