midbrain
Acronym: MBr
The term midbrain refers to one ot three components of the brain as defined by surgical dissection. The other components are the forebrain and the hindbrain.The central of the three, it's rostral boundary is with the forebrain: a nominally coronal plane located at the rostral margin of the superior colliculus dorsally and the caudal margin of the mammillary body ventrally. It's caudal boundary is with the hindbrain: a nominally coronal plane located at the caudal margin of the inferior colliculus dorsally and the rostral margin of the basal pons ventrally. The midbrain is composed of two parts: the tectum and the cerebral peduncle. Substructures of the midbrain are derived for the most part, but not entirely, from the embryonic Mesencephalon.
