Answer:
They are called mechanoreceptors.
Step-by-step explanation:
Mechanoreceptors are sensory receptors belonging to the peripheral nervous system. The functions of sensory receptors is to enable detection of changes (by way of stimuli) in the external environment and also monitor the internal environment. The stimuli are of various sources and different types.
Different types of cells sense different types of stimuli. Receptor cells that sense chemical stimuli are called chemoreceptors, osmoreceptors detect changes in solute concentration of body fluids, thermoreceptors sense temperature stimuli, nociceptors, and mechanoreceptors that sense pressure and vibration, sensation of sound and body position.
