Basic Divisions of the Midbrain
Tegmentum and Tectum
Cerebral Peduncles, Cerebral Crura and Colliculli





The midbrain consists of a larger anterior portion consisting of the cerebral peduncles, (green) the substantia nigra (black) and the tegmentum (light orange) that extends to the aqueduct (thin gray line) The posterior portion called tectum (orange) contains the colliculi (purple) which are the most posterior portions of the midbrain. brain anatomy neuroanatomy midbrain tegmentum colliculi tectum cerebral peduncle aqueduct of Sylvius conceptual diagram MRI principles

Basic Parts of the Midbrain




The midbrain consists of a larger anterior portion called the cerebral peduncles incorporated into the tegmentum or floor of the midbrain (orange ).  The  posterior portion is called tectum or the roof  (yellow/orange) and are separated by the aqueduct of Sylvius (black)

The Midbrain (orange) – A Bridge from the Forebrain (green)  to the Hindbrain (salmon)



The stick diagram starts to become more complex as the forebrain (green) demonstrates folds on its anterior and posterior extremes representing the fold of the frontal lobe anteriorly and temporal lobe posteriorly. The vertical limb also has a subtle angulation between the midbrain (yellow) and hind brain (salmon red).
