  2. Mechanoreceptor - Wikipedia

    en.wikipedia.org/wiki/Mechanoreceptor

    Cutaneous mechanoreceptors can also be separated into categories based on their rates of adaptation. When a mechanoreceptor receives a stimulus, it begins to fire impulses or action potentials at an elevated frequency (the stronger the stimulus, the higher the frequency).

  3. Mechanosensation - Wikipedia

    en.wikipedia.org/wiki/Mechanosensation

    Aδ fibers are characterized by thin axons and thin myelin sheaths, and are either D-hair receptors or nociceptive neurons. Aδ fibers conduct at a rate of up to 25 m/s. D-hair receptors have large receptive fields and very low mechanical thresholds, and have been shown to be the most sensitive of known cutaneous mechanoreceptors.

  4. Stimulus (physiology) - Wikipedia

    en.wikipedia.org/wiki/Stimulus_(physiology)

    Examples of mechanoreceptors include baroreceptors which detect changes in blood pressure, Merkel's discs which can detect sustained touch and pressure, and hair cells which detect sound stimuli. Homeostatic imbalances that can serve as internal stimuli include nutrient and ion levels in the blood, oxygen levels, and water levels.

  5. Group C nerve fiber - Wikipedia

    en.wikipedia.org/wiki/Group_C_nerve_fiber

    includes CT fibres, also known as C low-threshold mechanoreceptors (CLTM), which are unmyelinated afferents found in human hairy skin, and have a low mechanical threshold < 5 milliNewtons. They have moderate adaptation and may exhibit fatigue on repetitive stimulation and "afterdischarges" for several seconds after a stimulus.

  6. Pallesthesia - Wikipedia

    en.wikipedia.org/wiki/Pallesthesia

    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]

  7. Stimulus modality - Wikipedia

    en.wikipedia.org/wiki/Stimulus_modality

    Mechanoreceptors are classified in terms of their adaptation rate and the size of their receptive field. Specific mechanoreceptors and their functions include: [25] Thermoreceptors that detect changes in skin temperature. Kinesthetic receptors detect movements of the body, and the position of the limbs.

  8. Stretch receptor - Wikipedia

    en.wikipedia.org/wiki/Stretch_receptor

    Stretch receptors are mechanoreceptors responsive to distention of various organs and muscles, and are neurologically linked to the medulla in the brain stem via afferent nerve fibers. Examples include stretch receptors in the arm and leg muscles and tendons, in the heart, in the colon wall, and in the lungs.

  9. 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.
