Sense organs, simple receptors ?

Sense organs are specialized structures in the body that detect and respond to specific stimuli from the environment. They include the eyes, ears, nose, tongue, and skin. These organs contain sensory receptors that convert external stimuli into electrical signals that can be interpreted by the brain.

Simple receptors, on the other hand, are sensory receptors that are not part of a specific sense organ. They are found throughout the body and respond to basic stimuli such as pressure, temperature, and pain. Simple receptors are responsible for detecting and transmitting information about the body's internal and external environment to the brain. Examples of simple receptors include free nerve endings, Merkel discs, and Pacinian corpuscles.
