What is the primary function of sensory receptors in the nervous system?

The primary function of sensory receptors in the nervous system is to detect stimuli from the environment. These specialized cells are responsible for converting various forms of energy, such as light, sound, and chemical signals, into neural signals that the brain can interpret. This detection process allows organisms to perceive their surroundings and respond appropriately, contributing to survival and adaptability.

Sensory receptors are classified based on the type of stimuli they respond to, including photoreceptors for light, mechanoreceptors for pressure and vibration, thermoreceptors for temperature changes, chemoreceptors for taste and smell, and nociceptors for pain. By sensing changes in the environment, sensory receptors play a crucial role in helping individuals navigate and interact with their world effectively.
