Tectospinal tract
Script error: No such module "Distinguish". Script error: No such module "Infobox".Template:Template otherTemplate:Main other In humans, the tectospinal tract (or colliculospinal tract) is a decussating extrapyramidal tract that coordinates head/neck and eye movements.[1]
It arises from the superior colliculus of the mesencephalic (midbrain) tectum, and projects to the cervical and upper thoracic spinal cord levels.[2] It mediates reflex turning of the head and upper trunk in the direction of startling sensory stimuli (visual, auditory, or skin).[2]
It arises from the deep layers of the superior colliculus. It decussates within the posterior part of mesencephalic tegmentum at the level of the red nucleus.[1] It descends through the medulla oblongata near the midline within the medial longitudinal fasciculus.[1] In the spinal cord, it descends in the anterior funiculus.[1] It terminates by synapsing with interneurons of the intermediate zone and anterior grey column.[1]
