  2. Dorsal root ganglion - Wikipedia

    en.wikipedia.org/wiki/Dorsal_root_ganglion

    A dorsal root ganglion (or spinal ganglion; also known as a posterior root ganglion [1]) is a cluster of neurons (a ganglion) in a dorsal root of a spinal nerve. The cell bodies of sensory neurons known as first-order neurons are located in the dorsal root ganglia. [2] The axons of dorsal root ganglion neurons are known as afferents.

  3. Dorsal root of spinal nerve - Wikipedia

    en.wikipedia.org/wiki/Dorsal_root_of_spinal_nerve

    The root emerges from the posterior part of the spinal cord and travels to the dorsal root ganglion. The dorsal root ganglia contain the pseudo-unipolar cell bodies of the nerve fibres which travel from the ganglia through the root into the spinal cord. The lateral division of the dorsal root contains lightly myelinated and unmyelinated fibres ...

  4. Dorsal column–medial lemniscus pathway - Wikipedia

    en.wikipedia.org/wiki/Dorsal_column–medial...

    The body is situated in the dorsal root ganglion, with one axon traveling peripherally to tissue, and one traveling into the dorsal column. On the right is a bipolar neuron. When an action potential is generated by a mechanoreceptor in the tissue, the action potential will travel along the peripheral axon of the first-order neuron.

  5. Ganglion - Wikipedia

    en.wikipedia.org/wiki/Ganglion

    A dorsal root ganglion (DRG) from a chicken embryo (around stage of day 7) after incubation overnight in NGF growth medium stained with anti-neurofilament antibody. Note the axons growing out of the ganglion. A ganglion (pl.: ganglia) is a group of neuron cell bodies in the peripheral nervous system.

  6. Spinocerebellar tracts - Wikipedia

    en.wikipedia.org/wiki/Spinocerebellar_tracts

    All of these neurons are sensory (first order, or primary) and have their cell bodies in the dorsal root ganglia. They pass through Rexed laminae layers I-VI of the posterior grey column (dorsal horn) to form synapses with second order or secondary neurons in layer VII just beneath the dorsal horn.

  7. Afferent nerve fiber - Wikipedia

    en.wikipedia.org/wiki/Afferent_nerve_fiber

    Just outside the spinal cord, thousands of afferent neuronal cell bodies are aggregated in a swelling in the dorsal root known as the dorsal root ganglion. [1] [2] All of the axons in the dorsal root, which contains afferent nerve fibers, are used in the transduction of somatosensory information.

  8. Sensory neuronopathy - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuronopathy

    The dorsal root ganglion contains cell bodies for sensory nerves including large, myelinated Aβ fibers which carry proprioception and tactile touch sensation to the brain via the dorsal column–medial lemniscus pathway and small, unmyelinated C fibers which carry thermal and pain sensation to the brain via the spinothalamic tract. [2]

  9. Satellite glial cell - Wikipedia

    en.wikipedia.org/wiki/Satellite_glial_cell

    In the sympathetic ganglia, satellite glial cells are one of three main types of cells, the other two being the sympathetic ganglion neurons and small intensely fluorescent (SIF) cells. [3] SIF cells of sympathetic ganglia are separated into groups, each of which is surrounded by an SGC sheath. [19]
