The part of the brain—also called the mesencephalon—that contains the tectum, the tegmentum, the ventricular mesocoelia, and the cerebral peduncles. The midbrain adjoins the pons caudally and the diencephalon rostrally.
The middle of the three primitive enlargements of the developing brain in the embryo, connecting the pons and the cerebellum with the hemispheres of the cerebrum.
The small middle section of the brain stem above the pons and between the cerebrum and the hindbrain.
Part of the brain stem, joining the hindbrain and forebrain, and serving as passageway for impulses to higher brain centers; also called mesencephalon.
The middle region of the brain stem responsible for auditory and visual reflex centers.
The small portion of the brainstem, excluding the pons and the medulla, that joins the hindbrain to the forebrain.
The corpora quadrigemina, the crura cerebri, and aqueduct of Sylvius, which connect the pons and cerebellum with the hemispheres of the cerebrum. It contains reflex centers for eye and head movements in response to visual and auditory stimuli.
Region of the brain stem that controls and coordinates many sensory and motor activities such as the auditory and visual systems as well as voluntary motor movement.
The upper segment of the brainstem located above the pons is known as the midbrain, alternatively referred to as the mesencephalon.
