They are pressure receptors so respond to their stimuli-pressure :) hope this helps
Mechanoreceptors note touch and pressure.
Meissner's corpuscles
Arrector Pili - because it does not have sensory detection.
The Merkel's disks are the receptors for pressure.
This is a sense organ located on the finger tips and other parts of the skin in hairless areas. It is a group of cells that form an oval and are attached to a sensory nerve.
In part, yes. The nerve cell is what ensures the message of an external or internal stimulus gets to the brain so we are consiously aware of that stimulus. However, in order for a nerve cell to get the message, it must receive an input from a receptor. As such, the receptors at the end of a nerve cell are the most directly responsible for our sensitivity. Some examples of the receptors are: - nociceptors - mechanoreceptors (meissners corpuscles, etc.) - prorioreceptors (muscle spindles) - chemoreceptors (taste buds)
Because the hair folicule ending can detect hair movement and therefore pressure, so the meissner corpuscles are not needed.
Meissner's corpuscles
to detect stimulus
Sound
Meissner's corpuscles and Merkel discs
Pacinian corpuscle is sensitive to deep pressure.
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical
