Disorders
Disruption of the anterior spinal cord leads to bilateral disruption of the corticospinal tract, causing motor deficits, and bilateral disruption of the spinothalamic tract, causing sensory deficits in the form of pain/temperature sense loss. This is Anterior spinal artery syndrome. This occurs when the disruption of the anterior spinal artery is at the level of the spinal cord. Contrast this with Medial medullary syndrome when the anterior spinal artery is occluded at the level of the medulla. This causes different symptoms. It affects the cortiospinal tract - contralaterally, medial lemniscus - contralaterally, and hypoglossal nerve - ipsilaterally.

Famous quotes containing the word disorders:
“It no longer makes sense to speak of “feeding problems” or “sleep problems” or “negative behavior” is if they were distinct categories, but to speak of “problems of development” and to search for the meaning of feeding and sleep disturbances or behavior disorders in the developmental phase which has produced them.”
—Selma H. Fraiberg (20th century)
“A car can massage organs which no masseur can reach. It is the one remedy for the disorders of the great sympathetic nervous system.”
—Jean Cocteau (1889–1963)
