What is the function of sensory neurons?

The function of sensory neurons is to transmit signals from sensory receptors to the central nervous system. Sensory neurons are specialized cells that detect stimuli from the environment, such as light, sound, temperature, or touch. Once these sensory receptors perceive a stimulus, sensory neurons convey the information in the form of electrical impulses to the brain and spinal cord, where it can be processed and interpreted.

This role is crucial because it allows the body to respond to changes in the environment, facilitating awareness and interaction with surroundings. In contrast, other options might mischaracterize the responsibilities of different types of neurons or biological functions; for instance, motor neurons are responsible for transmitting signals to muscles, and reflex actions involve an immediate response typically initiated by interneurons rather than sensory neurons alone. Hormonal regulation is the function of the endocrine system, not of sensory neurons.
