Poliomyelitis, or gray matter myelitis, is usually caused by infection of anterior horn of the spinal cord by the enteroviruses (polioviruses, enteroviruses (EV) 70 and 71, echoviruses, coxsackieviruses A and B) and the flaviviruses (West Nile, Japanese encephalitis, tick-borne encephalitis).
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.
The four main divisions of the spinal column, from top to bottom: cervical, thoracic, lumbar, and sacral. The lateral grey column (lateral column, lateral cornu, lateral horn of spinal cord, intermediolateral column) is one of the three grey columns of the spinal cord (which give the shape of a butterfly); the others being the anterior and posterior grey columns.
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 ...

This information is then transmitted in axons up the spinal cord in spinal tracts, including the dorsal column-medial lemniscus tract and the spinothalamic tract. The lateral grey column is the third column of the spinal cord. The grey matter of the spinal cord can be divided into different layers, called Rexed laminae. These describe, in ...
Subacute combined degeneration of spinal cord, also known as myelosis funiculus, or funicular myelosis, [1] also Lichtheim's disease, [2] [3] and Putnam-Dana syndrome, [4] refers to degeneration of the posterior and lateral columns of the spinal cord as a result of vitamin B 12 deficiency (most common).
The intermediolateral nucleus (IML) is located in Rexed lamina VII of the lateral grey column, one of three grey matter columns found in the spinal cord. The intermediolateral cell column exists at vertebral levels T1 – L3. [1] It mediates the entire sympathetic innervation of the body, but the nucleus resides in the grey matter of the spinal ...
