  2. Grey columns - Wikipedia

    en.wikipedia.org/wiki/Grey_columns

    Spinal lamina V, the neck of the posterior horn [9] Spinal lamina VI, the base of the posterior horn. The other four laminae are located in the other two grey columns in the spinal cord. The function of the spinal dorsal horn is to process and integrate sensory information from the peripheral nervous system.

  3. Posterior horn - Wikipedia

    en.wikipedia.org/wiki/Posterior_horn

    Posterior horn of lateral ventricle in the brain, which passes forward, laterally and slightly downward, from the corpus callosum into the occipital lobe Posterior horn of spinal cord , the dorsal (towards the back) grey matter section of the spinal cord that receives several types of sensory information from the body including light touch ...

  4. Spinal cord - Wikipedia

    en.wikipedia.org/wiki/Spinal_cord

    Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...

    en.wikipedia.org/wiki/Rexed_laminae

    Lamina VII: intermediomedial nucleus, intermediolateral nucleus, posterior thoracic nucleus in the thoracic and upper lumbar region [6] Lamina X: an area of grey matter – the grey commissure surrounding the central canal. This region also serves to connect the anterior and posterior grey columns. [3] Rexed never described this as lamina X but ...

  6. Spinal column - Wikipedia

    en.wikipedia.org/wiki/Spinal_column

    Spinal cord injury is damage to the spinal cord that causes changes in its function, either temporary or permanent. Spinal cord injuries can be divided into categories: complete transection, hemisection, central spinal cord lesions, posterior spinal cord lesions, and anterior spinal cord lesions.

  7. Marginal nucleus of spinal cord - Wikipedia

    en.wikipedia.org/.../Marginal_nucleus_of_spinal_cord

    The marginal nucleus of spinal cord, posteromarginal nucleus, or spinal lamina 1 (Rexed lamina 1) is located at the most dorsal aspect of the posterior grey column of the spinal cord. The neurons located here receive input primarily from Lissauer's tract and relay information related to pain and temperature sensation.

  8. Dorsal column–medial lemniscus pathway - Wikipedia

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

    The action signal will continue along the central axon of the neuron through the posterior root, into the posterior horn, and up the posterior column of the spinal cord. Axons from the lower body enter the posterior column below the level of T6 and travel in the midline section of the column called the gracile fasciculus. [ 5 ]

  9. Substantia gelatinosa of Rolando - Wikipedia

    en.wikipedia.org/wiki/Substantia_gelatinosa_of...

    The apex of the posterior grey column, one of the three grey columns of the spinal cord, is capped by a V-shaped or crescentic mass of translucent, gelatinous neuroglia, termed the substantia gelatinosa of Rolando (or SGR) (or gelatinous substance of posterior horn of spinal cord), which contains both neuroglia cells, and small neurons.
