2. Sensory Receptors Mechanoreceptors Thermoreceptors
Most are found in the skin, but some can be found in the hair as well
They are sensitive to mechanical stimuli such as pressure, gravity, and sound waves
Thermoreceptors
These are also found in the skin
They are used to detect hold and cold temperatures

3. Sensory Receptors Chemoreceptors Photoreceptors
These are found in the mouth on the tongue, and in the nose
They are used to smell and taste substances
Photoreceptors
These are found in the eyes
These receptors absorb light energy and trigger action potentials. They help us to see.

4. Sensory Receptors Pain Receptors These receptors are found in skin
They detect severe
heat and pressure and
chemicals released by
inflamed tissue
The free nerve endings
allow us to feel pain
