  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 dorsal root of spinal nerve (or posterior root of spinal nerve or sensory root) [1] is one of two "roots" which emerge from the spinal cord. It emerges directly from the spinal cord, and travels to the dorsal root ganglion. Nerve fibres with the ventral root then combine to form a spinal nerve.

  4. Complex regional pain syndrome - Wikipedia

    en.wikipedia.org/wiki/Complex_regional_pain_syndrome

    Dorsal root ganglion stimulation is a type of neurostimulation that is effective in the management of focal neuropathic pain. The FDA approved its use in February 2016. The ACCURATE Study demonstrated superiority of dorsal root ganglion stimulation over spinal (dorsal column) stimulation in the management of CRPS and causalgia. [62]

  5. Somatosensory system - Wikipedia

    en.wikipedia.org/wiki/Somatosensory_system

    The first-order neuron is a type of pseudounipolar neuron and always has its cell body in the dorsal root ganglion of the spinal nerve with a peripheral axon innervating touch mechanoreceptors and a central axon synapsing on the second-order neuron.

  6. 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.

  7. 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]

  8. Sensory neuron - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuron

    The cell bodies of the sensory neurons are located in the dorsal root ganglia of the spinal cord. [2] The sensory information travels on the afferent nerve fibers in a sensory nerve, to the brain via the spinal cord. Spinal nerves transmit external sensations via sensory nerves to the brain through the spinal cord. [3]

  9. Posterolateral tract - Wikipedia

    en.wikipedia.org/wiki/Posterolateral_tract

    The posterolateral tract contains centrally projecting axons from dorsal root ganglion cells carrying peripheral pain and temperature information (location, intensity and quality). These axons enter the spinal column and penetrate the grey matter of the dorsal horn, where they synapse on second-order neurons in either the substantia gelatinosa ...
