1. Mechanoreceptors

2. Mechanoreceptors
- Mechanoreceptors are stimulated by mechanical compression or stretch at the receptor or surrounding tissues. - Found in skin for sensing contact with physical world. -Found in bladder, blood vessels, heart, digestive .organs, and teeth to sense pressure - Mechanoreceptors are innervated by myelineated axons.

3. Mechanoreceptors
:Receptors can be classified according to the type of stimulus into
1-Tocuh receptors in the skin which are stimulated by light mechanical stimuli.
2-Pressure receptors in the subcutaneous tissues which are stimulated by
deep mechanical stimuli.
3-Stretch receptors in the skeletal muscles, lungs, right atrium, urinary
bladder, stomach, intestine and rectum.
4-Joint receptors which send information about the position and movement
of the of the joint.
5- Auditory receptors which are stimulated by sound waves
