  2. Ganglion cell - Wikipedia

    en.wikipedia.org/wiki/Ganglion_cell

    Examples of ganglion cells include: Retinal ganglion cell (RGC) found in the ganglion cell layer of the retina [1] Cells that reside in the adrenal medulla, where they are involved in the sympathetic nervous system's release of epinephrine and norepinephrine into the blood stream; Cells of the sympathetic ganglia; Cells of the parasympathetic ...

  3. Ganglion - Wikipedia

    en.wikipedia.org/wiki/Ganglion

    A ganglion (pl.: ganglia) is a group of neuron cell bodies in the peripheral nervous system. In the somatic nervous system , this includes dorsal root ganglia and trigeminal ganglia among a few others.

  4. Retinal ganglion cell - Wikipedia

    en.wikipedia.org/wiki/Retinal_ganglion_cell

    P-type retinal ganglion cells project to the parvocellular layers of the lateral geniculate nucleus. These cells are known as midget retinal ganglion cells, based on the small sizes of their dendritic trees and cell bodies. About 80% of all retinal ganglion cells are midget cells in the parvocellular pathway. They receive inputs from relatively ...

  5. Ganglion cell layer - Wikipedia

    en.wikipedia.org/wiki/Ganglion_cell_layer

    In the anatomy of the eye, the ganglion cell layer (ganglionic layer) is a layer of the retina that consists of retinal ganglion cells and displaced amacrine cells. The cells are somewhat flask -shaped; the rounded internal surface of each resting on the stratum opticum , and sending off an axon which is prolonged into it.

  6. Autonomic ganglion - Wikipedia

    en.wikipedia.org/wiki/Autonomic_ganglion

    An autonomic ganglion is a cluster of nerve cell bodies (a ganglion) in the autonomic nervous system. The two types are the sympathetic ganglion and the parasympathetic ganglion . [ 1 ] [ 2 ]

  7. Midget cell - Wikipedia

    en.wikipedia.org/wiki/Midget_cell

    The axons of midget cells travel through the optic nerve and optic tract, ultimately synapsing with parvocellular cells in the LGN. These cells are known as midget retinal ganglion cells due to the small sizes of their dendritic trees and cell bodies. About 80% of RGCs are midget cells. They receive inputs from relatively few rods and cones.

  8. Sensory nervous system - Wikipedia

    en.wikipedia.org/wiki/Sensory_nervous_system

    Ganglion cells reside in the adrenal medulla and retina where they are involved in the sympathetic response. Of the ~1.3 million ganglion cells present in the retina, 1–2% are believed to be photosensitive ganglia. [10] These photosensitive ganglia play a role in conscious vision for some animals, [11] and are believed to do the same in ...

  9. Lateral geniculate nucleus - Wikipedia

    en.wikipedia.org/wiki/Lateral_geniculate_nucleus

    Retinal P ganglion cells send axons to a parvocellular layer, M ganglion cells send axons to a magnocellular layer, and K ganglion cells send axons to a koniocellular layer. [6]: 269 Koniocellular cells are functionally and neurochemically distinct from M and P cells and provide a third channel to the visual cortex. They project their axons ...
