The Pacinian corpuscle (also lamellar corpuscle, or Vater-Pacini corpuscle) [1] is a low-threshold mechanoreceptor responsive to vibration or pressure, found in the skin and other internal organs. [2] In the skin it is one of the four main types of cutaneous receptors. The corpuscles are present in skin notably on both surfaces of the hands and ...
The Pacinian corpuscle or Vater-Pacinian corpuscles or Lamellar corpuscles [5] in the skin and fascia detect rapid vibrations of about 200–300 Hz. [3] [6] They also produce transient responses, but have large receptive fields. Free nerve endings detect touch, pressure, stretching, as well as the tickle and itch sensations. Itch sensations are ...
Pallesthesia (\ˌpal-es-ˈthē-zh (ē-)ə\), or vibratory sensation, is the ability to perceive vibration. [1][2] This sensation, often conducted through skin and bone, is usually generated by mechanoreceptors such as Pacinian corpuscles, Merkel disk receptors, and tactile corpuscles. [1] All of these receptors stimulate an action potential in ...
Baroreceptor. Baroreceptors (or archaically, pressoreceptors) are sensors located in the carotid sinus (at the bifurcation of common carotid artery into external and internal carotids) and in the aortic arch. [1] They sense the blood pressure and relay the information to the brain, so that a proper blood pressure can be maintained.
Furthermore, mechanically gated ion channels are also found in the stereocilia of the inner ear. Sound waves are able to bend the stereocilia and open up ion channels leading to the creation of nerve impulses. [63] These channels also play a role in sensing vibration and pressure via activation of Pacinian corpuscles in the skin. [64]
Dorsal column–medial lemniscus pathway. The formation of the spinal nerve from the dorsal and ventral roots. Originating in peripheral sensory receptors, the dorsal column-medial lemniscus pathway transmits fine touch and conscious proprioceptive information to the brain. The dorsal column–medial lemniscus pathway (DCML) (also known as the ...
The carotid body is a small cluster of peripheral chemoreceptor cells and supporting sustentacular cells situated at the bifurcation of each common carotid artery in its tunica externa. [1][2] The carotid body detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of arterial oxygen, but also of ...
Anatomical terms of microanatomy. [edit on Wikidata] Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges, blood vessels, and ducts. The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells, also ...
