The receptors that receive stimuli from the outside are called exteroceptors. These receptors are responsible for detecting stimuli from the external environment and transmitting this information to the brain. Examples of exteroceptors include:
1. Gustatory receptors: These receptors are responsible for detecting taste stimuli, such as sweet, sour, bitter, salty, and umami flavors. They are located on the taste buds on the tongue and the roof of the mouth.
2. Skin receptors: Skin receptors are responsible for detecting various stimuli such as touch, pressure, temperature, and pain. They are located throughout the skin and help us sense our environment and respond to stimuli like heat, cold, or pressure.
3. Photoreceptors: Photoreceptors are specialized cells in the retina of the eye that detect light stimuli. They enable us to see and perceive visual information from the external environment.
Therefore, in the context of the question, the correct answer would be that exteroceptors are the receptors that receive stimuli from the outside.
