Which sensory receptor type primarily detects pressure changes?

Mechanoreceptors are specialized sensory receptors responsible for detecting mechanical changes in the environment, such as pressure, touch, vibrations, and stretch. These receptors are sensitive to physical deformation caused by mechanical forces. When pressure changes occur, mechanoreceptors respond by altering their state of polarization, which leads to the generation of nerve impulses that are transmitted to the central nervous system for processing.

For instance, in the skin, various types of mechanoreceptors, such as Pacinian and Meissner's corpuscles, are specifically attuned to detect different pressure levels and textures, allowing us to perceive sensations like the light touch of a breeze or the firm pressure of a grip. This ability is crucial for various functions, including spatial awareness, proprioception, and fine motor skills in everyday activities.
