They can be found at a depth of 900 μm in human fingertips. [4] In hairy skin, Merkel nerve endings are clustered into specialized epithelial structures called "touch domes" or "hair disks". Merkel receptors are also located in the mammary glands. Wherever they are found, the epithelium is arranged to optimize the transfer of pressure to the ...
Merkel cells, also known as Merkel–Ranvier cells or tactile epithelial cells, are oval-shaped mechanoreceptors essential for light touch sensation and found in the skin of vertebrates. They are abundant in highly sensitive skin like that of the fingertips in humans , and make synaptic contacts with somatosensory afferent nerve fibers .
The nature–culture divide is the notion of a dichotomy between humans and the environment. [1] It is a theoretical foundation of contemporary anthropology that considers whether nature and culture function separately from one another, or if they are in a continuous biotic relationship with each other.
A mechanoreceptor, also called mechanoceptor, is a sensory receptor that responds to mechanical pressure or distortion. Mechanoreceptors are located on sensory neurons that convert mechanical pressure into electrical signals that, in animals, are sent to the central nervous system.
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]
The Kulturkreis (roughly, "culture circle" or "cultural field") school was a central idea of the early 20th-century German school of anthropology that sought to redirect the discipline away from the quest for an underlying, universal human nature toward a concern with the particular histories of individual societies. It was the notion of a ...
The system relied heavily on use of a mouse before it was common to have one and was an attempt to make the desktop operating system relatively affordable, according to BYTE Magazine.
The Merkel-Raute [1] (German for "Merkel rhombus"), termed the Merkel diamond [2] or Triangle of Power by English-speaking media, [3] is a hand gesture made by resting one's hands in front of the stomach so that the fingertips meet, with the thumbs and index fingers forming a rough quadrangular shape.
