sensation of pressure changes
A
statocyst
B
mechanorecption
C
hair cells
D
stereocilia
Explanation: 

Detailed explanation-1: -mechanoreception, ability of an animal to detect and respond to certain kinds of stimuli-notably touch, sound, and changes in pressure or posture-in its environment. Sensitivity to mechanical stimuli is a common endowment among animals.

Detailed explanation-2: -Cutaneous mechanoreceptors. Cutaneous mechanoreceptors respond to mechanical stimuli that result from physical interaction, including pressure and vibration. They are located in the skin, like other cutaneous receptors.

Detailed explanation-3: -Mechanoreceptors. Mechanoreceptors detect stimuli such as touch, pressure, vibration, and sound from the external and internal environments. They contain primary sensory neurons that respond to changes in mechanical displacement, usually in a localized region at the tip of a sensory dendrite.

Detailed explanation-4: -Mechanoreceptors are an important receptor class for the somatosensory system. These receptors have a well-known role in tactile feedback from the skin and skeletal system, which is essential for human development and sensation.

Detailed explanation-5: -Mechanoreceptors are one of the neural receptors in a somatosensory system. They are primarily involved in recognizing different mechanical stimuli. Example is the touch receptor in the skin. Insects are popular example of group of organisms with specialized structures for mechanoreception.
