  2. Shingles - Wikipedia

    en.wikipedia.org/wiki/Shingles

    In 1831 Richard Bright hypothesized that the disease arose from the dorsal root ganglion, and an 1861 paper by Felix von Bärensprung confirmed this. [103] Recognition that chickenpox and shingles were caused by the same virus came at the beginning of the 20th century.

    en.wikipedia.org/wiki/Portal:Viruses/Selected...

    Shingles is caused by varicella zoster virus (VZV), an alpha-herpesvirus. Initial VZV infection usually occurs in childhood causing chickenpox. After this resolves, the virus is not eliminated from the body, but remains latent in the nerve cell bodies of the dorsal root or trigeminal ganglia, without causing symptoms.

  4. Varicella zoster virus - Wikipedia

    en.wikipedia.org/wiki/Varicella_zoster_virus

    Similar to the herpes simplex viruses, after primary infection with VZV (chickenpox), the virus lies dormant in neurons, including the cranial nerve ganglia, dorsal root ganglia, and autonomic ganglia. Many years after the person has recovered from initial chickenpox infection, VZV can reactivate to cause shingles. [4]

  5. 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.

  6. Postherpetic neuralgia - Wikipedia

    en.wikipedia.org/wiki/Postherpetic_neuralgia

    Postherpetic neuralgia (PHN) is neuropathic pain that occurs due to damage to a peripheral nerve caused by the reactivation of the varicella zoster virus (herpes zoster, also known as shingles). PHN is defined as pain in a dermatomal distribution that lasts for at least 90 days after an outbreak of herpes zoster. [ 1 ]

  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. 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.

  9. Dermatome (anatomy) - Wikipedia

    en.wikipedia.org/wiki/Dermatome_(anatomy)

    A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion. Symptoms that follow a dermatome (e.g. like pain or a rash) may indicate a pathology that involves the related nerve root. Examples include somatic dysfunction of the spine or viral infection.
