|Anterior horn (spinal cord)|
|Latin||cornu anterius medullae spinalis|
|Gray's||subject #185 753|
It is these cells that are affected in the so-called "Anterior Horn Diseases", namely Amyotrophic Lateral Sclerosis, Spinal muscular atrophy, Charcot-Marie-Tooth disease and Progressive muscular atrophy.
The Anterior Column (anterior cornu, anterior horn), directed forward, is broad and of a rounded or quadrangular shape.
Its posterior part is termed the base, and its anterior part the head, but these are not differentiated from each other by any well-defined constriction.
It is separated from the surface of the medulla spinalis by a layer of white substance which is traversed by the bundles of the anterior nerve roots.
In the thoracic region, the postero-lateral part of the anterior column projects lateralward as a triangular field, which is named the lateral column (columna lateralis; lateral cornu).
