  2. Nociceptor - Wikipedia

    en.wikipedia.org/wiki/Nociceptor

    For example, in fruit flies, specific multidendritic sensory neurons play a role in nociception. [22] In mollusks, nociceptive responses are mediated by pedal sensory neurons. [ 23 ] [ 24 ] Crustaceans, on the other hand, utilize a variety of sensory cell types, including chordotonal organs and mechanoreceptors, to detect potentially damaging ...

  3. Sensory nerve - Wikipedia

    en.wikipedia.org/wiki/Sensory_nerve

    A sensory nerve, or afferent nerve, is an anatomic term for a nerve that contains exclusively afferent nerve fibers. [1] Nerves containing also motor fibers are called mixed . Afferent nerve fibers in a sensory nerve carry sensory information toward the central nervous system (CNS) from different sensory receptors of sensory neurons in the ...

  4. Sensory neuron - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuron

    Spinal nerves transmit external sensations via sensory nerves to the brain through the spinal cord. [3] The stimulus can come from exteroreceptors outside the body, for example those that detect light and sound, or from interoreceptors inside the body, for example those that are responsive to blood pressure or the sense of body position .

  5. Nociception - Wikipedia

    en.wikipedia.org/wiki/Nociception

    In nociception, intense chemical (e.g., capsaicin present in chili pepper or cayenne pepper), mechanical (e.g., cutting, crushing), or thermal (heat and cold) stimulation of sensory neurons called nociceptors produces a signal that travels along a chain of nerve fibers via the spinal cord to the brain. [1]

  6. Law of specific nerve energies - Wikipedia

    en.wikipedia.org/wiki/Law_of_specific_nerve_energies

    Here is Müller's statement of the law, from Handbuch der Physiologie des Menschen für Vorlesungen, 2nd Ed., translated by Edwin Clarke and Charles Donald O'Malley: . The same cause, such as electricity, can simultaneously affect all sensory organs, since they are all sensitive to it; and yet, every sensory nerve reacts to it differently; one nerve perceives it as light, another hears its ...

  7. Sural nerve - Wikipedia

    en.wikipedia.org/wiki/Sural_nerve

    The sural nerve (L4-S1) is a cutaneous sensory nerve of the posterolateral calf with cutaneous innervation to the distal one-third of the lower leg. [1] Formation of the sural nerve is the result of either anastomosis of the medial sural cutaneous nerve and the sural communicating nerve, or it may be found as a continuation of the lateral sural cutaneous nerve [2] traveling parallel to the ...

  8. Reflex arc - Wikipedia

    en.wikipedia.org/wiki/Reflex_arc

    Effector muscle innervated by the efferent nerve fiber carries out the response. A reflex arc, then, is the pathway followed by nerves which (a.) carry sensory information from the receptor to the spinal cord, and then (b.) carry the response generated by the spinal cord to effector organs during a reflex action.

  9. Sensory nervous system - Wikipedia

    en.wikipedia.org/wiki/Sensory_nervous_system

    A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception and interoception. Commonly recognized sensory systems are those for vision , hearing , touch , taste , smell , balance and visceral sensation.
