Term Detail

MP term:	abnormal pretectal region morphology
Synonym:	abnormal pretectal area morphology
Synonym:	abnormal pretectum morphology
Synonym:	abnormal PRT morphology
MP id:	MP:0009637
Definition:	any structural anomaly of a narrow, transversely oriented rostral zone of the mesencephalic tectum, bounded caudally by the superior colliculus, rostrally by the habenular trigone, and laterally by the pulvinar thalami; the pretectal area contains several nuclei that receive fibers from the optic tract; it has bilateral efferent connections with the Edinger-Westphal nucleus of the oculomotor nuclear complex by way of which it mediates the pupillary light reflex
