Sensory System


What are sensory receptors?

Sensory receptors are structures in the skin and other tissues that detect changes in the internal or external environment. These receptors consist of specialized neuron endings or specialized cells in close contact with neurons that convert the energy of the stimulus (sound, color, odor, etc.) to electrical signals within the nervous system. Sensory receptors, together with other cells, compose the major sense organs, including eyes, ears, nose, and taste buds.
