  2. Free nerve ending - Wikipedia

    en.wikipedia.org/wiki/Free_nerve_ending

    Anatomical terms of neuroanatomy. [edit on Wikidata] A free nerve ending (FNE) or bare nerve ending, is an unspecialized, afferent nerve fiber sending its signal to a sensory neuron. Afferent in this case means bringing information from the body's periphery toward the brain. They function as cutaneous nociceptors and are essentially used by ...

  3. Tactile corpuscle - Wikipedia

    en.wikipedia.org/wiki/Tactile_corpuscle

    Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner. [1][2] This corpuscle is a type of nerve ending in the skin that is responsible for sensitivity to pressure. In particular, they have their highest sensitivity (lowest threshold) when sensing ...

  4. Merkel nerve ending - Wikipedia

    en.wikipedia.org/wiki/Merkel_nerve_ending

    Merkel nerve ending. Merkel nerve endings are mechanoreceptors, a type of sensory receptor, that are found in the basal epidermis and hair follicles. They are nerve endings and provide information on mechanical pressure, position, and deep static touch features, such as shapes and edges. Merkel cells in the basal epidermis of the skin store ...

  5. Sensory neuron - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuron

    Free nerve endings characterize the nociceptors and thermoreceptors and are called thus because the terminal branches of the neuron are unmyelinated and spread throughout the dermis and epidermis. Encapsulated receptors consist of the remaining types of cutaneous receptors. Encapsulation exists for specialized functioning.

  6. Merkel cell - Wikipedia

    en.wikipedia.org/wiki/Merkel_cell

    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.

  7. Mechanoreceptor - Wikipedia

    en.wikipedia.org/wiki/Mechanoreceptor

    Mechanoreceptor. A mechanoreceptor, also called mechanoceptor, is a sensory receptor that responds to mechanical pressure or distortion. Mechanoreceptors are innervated by sensory neurons that convert mechanical pressure into electrical signals that, in animals, are sent to the central nervous system.

  8. Group C nerve fiber - Wikipedia

    en.wikipedia.org/wiki/Group_C_nerve_fiber

    The vanilloid receptor (VR-1, TRPV1) is a receptor that is found on the free nerve endings of both C and Aδ fibers that responds to elevated levels of heat (>43 °C) and the chemical capsaicin. [10] Capsaicin activates C fibers by opening a ligand-gated ion channel and causing an action potential to occur. [10]

    By comparison, the palm of one’s hand has 17,000 nerve endings — in a much, much larger area. Yet this study on the clitoris provides more than just a fun fact — it also can have major ...
