What are mechanoreceptors?

• Structures in the body that produce mechanical movements in response to electrical signals from the brain

• Chemical sensors in the body that detect odors and tastes through interaction with airborne or dissolved molecules

• The receptors in your muscles

• Specialized sensory receptors that respond to mechanical stimuli such as pressure, touch, vibration, stretch, and tension.
