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 general, the purpose of the cells within the grey matter of the spinal cord at a particular location.
The grey columns are three regions of the somewhat ridge-shaped mass of grey matter in the spinal cord. [1] These regions present as three columns: the anterior grey column , the posterior grey column , and the lateral grey column , all of which are visible in cross-section of the spinal cord.
The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the lower brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals. The center of the spinal cord is hollow and contains a structure called the central canal, which contains cerebrospinal fluid.
Spinal cord - grey matter Rexed laminae Look up Rexed lamina in Wiktionary, the free dictionary. The Rexed laminae (singular: Rexed lamina) comprise a system of ten layers of grey matter (I–X), identified in the early 1950s by Bror Rexed to label portions of the grey columns of the spinal cord .
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.
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 ...
White matter forms the bulk of the deep parts of the brain and the superficial parts of the spinal cord. Aggregates of grey matter such as the basal ganglia (caudate nucleus, putamen, globus pallidus, substantia nigra, subthalamic nucleus, nucleus accumbens) and brainstem nuclei (red nucleus, cranial nerve nuclei) are spread within the cerebral ...
The nucleus proprius of spinal cord is a layer of the spinal cord adjacent to the substantia gelatinosa. The nucleus proprius can be found in the gray matter in all levels of the spinal cord. It constitutes the first synapse of the posterior gray column carrying proprioception, two-point discrimination, and vibration sensations from peripheral ...
