What cannot be detected by a mechanoreceptor?

Mechanoreceptors are specialized sensory receptors that detect mechanical stimuli such as pressure, vibration, and stretch. However, they cannot detect chemical stimuli, such as changes in pH or the presence of specific molecules, which are sensed by chemoreceptors. Additionally, mechanoreceptors do not respond to thermal stimuli, which are detected by thermoreceptors. Thus, while crucial for sensing mechanical changes, mechanoreceptors have limitations in detecting other types of sensory information.
