Concept: Sensory Receptors
Explanation:
Responding to stimuli is a special feature of sense organs in living organisms, which make us able to quick respond to stimulus.
A human body has five sensory receptors,
⦁ chemoreceptors
⦁ nociceptors/pain receptors
⦁ thermoreceptors
⦁ mechanoreceptors
⦁ photoreceptors
which respond to different-different stimuli and are located in different locations.
i.e.
⦁ chemoreceptors; respond to smell, taste or any changes in the chemical concentration of substances.
⦁ nociceptors/pain receptors; they respond to any kind of pain.
⦁ thermoreceptors; they respond to change in temperature.
⦁ mechanoreceptors; they respond to touch, vibration, pressure or any kind of movement.
⦁ photoreceptors; are the visual receptors of the retina , they respond to light.
our skin has three receptors, Mechanoreceptors, thermoreceptors, and nociceptors. That's why it is stimulus to heat, cold, and pain not light.
