What are the different types of somatic receptors and their functions?
Terminations of hair follicles
Free nerve endings
Pacinian corpuscles
Meissner's corpuscles
Merkel's discs
Ruffini's corpuscles
Krause's bulbs
The sensitivity to pressure and touch are mecanoreceptive modalities that are based on increased conductivity to cations and depolarization in receptors that can be very different.
The size of the receptive fields qualifies somatic sensitivity.
The body has free nerve endings that are morphologically similar and sensitive to mechanical, thermal, or chemical stimuli, and can generate sensations of pressure, heat, cold, or pain.
Pacinian corpuscles are encapsulated nerve endings by a set of connective lamellae, associated with Aβ fibers, and can be found in the dermis, periosteum, peritoneum, and various viscera.
Meissner's corpuscles are rapid-adapting mechanoreceptors, associated with Aβ fibers, and are found mainly in the transition from the dermis to the glabrous skin.
Merkel's discs are nerve endings of myelinated fibers, and form discs that associate with Merkel cells. These cells establish a synaptic contact, where the Merkel cell transfers the information to the myelinated Aβ afferent fiber.
Ruffini's corpuscles are terminal arborizations of Aβ fibers inserted into a collagen-rich fibrous capsule, located deep in the dermis.
Krause's bulbs appear in chains on the edges of the skin and mucous membranes, around the lips and genitals. They are composed of encapsulated terminations of Aβ fibers, with an undefined function.
