mechanoreceptors

specialized sensory nerve endings at termini of A-beta nerve fibres; preferentially subserve mechanosensation, e.g. touch, vibration (see Table 1)

In fact, you won't even realize you are stimulating your brain as you listen to music or watch a movie while tracing your injected plastic device equipped with sharp-like protrusions and recessions to indent into mechanoreceptors in the fingertips to stimulate your brain.
I could conclude that numbers of sensilla on antennomers were varied according to length of antenna and functions assigned to ant members and pores of antennae determine the signals will be received by ant antennae, whereas antennae with pores were chemoreceptors but without pores were mechanoreceptors.
6 mm and one taxel is close to the size of the mechanoreceptors in the human skin.
Another point about the presence of possibly similar exposed ciliated mechanoreceptors in a variety of Asian as well African barbs is that they may have evolved independently, hence may represent an ancient recurrent adaptive feature of cyprinoids.
In addition, local upper airway mechanoreceptors respond to subatmospheric (negative or suction) pressure and modulate genioglossus activity (79-82).

Avian wings possess several mechanoreceptors to airflow localized on or near specific contour feathers and filoplumes' follicles.
Why is it crucial for us to understand what cells do (rods and cones perceive light by conformational changes in light-absorbing-molecules in their outer membranes; cochlear mechanoreceptors [hair cells] translate sound waves into action potentials which ultimately exit the cochlea via the auditory nerve)?
The mechanoreceptors can estimate the shear stress at the wall and pass the corresponding signal into the middle (smooth muscle) layer.
