  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. 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.

  5. 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.

  6. 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.

  7. 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]

  8. Spinal canal - Wikipedia

    en.wikipedia.org/wiki/Spinal_canal

    In human anatomy, the spinal canal, vertebral canal or spinal cavity is an elongated body cavity enclosed within the dorsal bony arches of the vertebral column, which contains the spinal cord, spinal roots and dorsal root ganglia. It is a process of the dorsal body cavity formed by alignment of the vertebral foramina.

  9. Unipolar neuron - Wikipedia

    en.wikipedia.org/wiki/Unipolar_neuron

    The pseudounipolar neuron's axon then splits into two branches. Sensory neurons with cell bodies in the dorsal root ganglia of the vertebrate spinal cord are pseudo-unipolar: one branch projects to the periphery (to sensory receptors in the skin, joints, and muscle), the other to the spinal cord.
