  2. Sensory neuron - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuron

    Four types of sensory neuron. Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials. [1] This process is called sensory transduction.

  3. Axon - Wikipedia

    en.wikipedia.org/wiki/Axon

    In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent nerve fibers and the electrical impulse travels along these from the periphery to the cell body and from the cell body to the spinal cord along another branch of the same axon.

  4. Sensory nervous system - Wikipedia

    en.wikipedia.org/wiki/Sensory_nervous_system

    The sensory nervous system is a part of the nervous system responsible for processing sensory information. 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 .

  5. Development of the nervous system in humans - Wikipedia

    en.wikipedia.org/wiki/Development_of_the_nervous...

    Once the neurons have reached their regional positions, they extend axons and dendrites, which allow them to communicate with other neurons via synapses. Synaptic communication between neurons leads to the establishment of functional neural circuits that mediate sensory and motor processing, and underlie behavior. [4]

  6. Sense of smell - Wikipedia

    en.wikipedia.org/wiki/Sense_of_smell

    The sensory receptors of the accessory olfactory system are located in the vomeronasal organ. As in the main olfactory system, the axons of these sensory neurons project from the vomeronasal organ to the accessory olfactory bulb, which in the mouse is located on the dorsal-posterior portion of the main olfactory bulb.

  7. Olfactory epithelium - Wikipedia

    en.wikipedia.org/wiki/Olfactory_epithelium

    The olfactory epithelium contains olfactory sensory neurons, whose axons innervate the olfactory bulb. In order for olfactory sensory neurons to function properly, they must express odorant receptors and the proper transduction proteins on non-motile cilia that extend from the dendritic knob in addition to projecting their axons to the ...

  8. Olfactory bulb - Wikipedia

    en.wikipedia.org/wiki/Olfactory_bulb

    Axons of the vomeronasal sensory neurons express a given receptor type which, differently from what occurs in the main olfactory bulb, diverge between 6 and 30 AOB glomeruli. Mitral cell dendritic endings go through a dramatic period of targeting and clustering just after presynaptic unification of the sensory neuron axons.

  9. 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.
