MSH: The middle of the three primitive cerebral vesicles of the embryonic brain. Without further subdivision, midbrain develops into a short, constricted portion connecting the PONS and the DIENCEPHALON. Midbrain contains two major parts, the dorsal TECTUM MESENCEPHALI and the ventral TEGMENTUM MESENCEPHALI, housing components of auditory, visual, and other sensorimoter systems.,CSP: develops from the middle of the 3 primary vesicles of the embryonic neural tube, between the prosencephalon and rhombencephalon, later forming the tectum and cerebral peduncles.,FMA: Organ component of neuraxis that has as its parts the tectum, cerebral peduncle, midbrain tegmentum and cerebral aqueduct. Examples: There is only one midbrain.,NCI: The uppermost portion of the brainstem located between the pons and the diencephalon. The midbrain contains the cerebral peduncles, oculomotor, trochlear and red nuclei, substantia nigra and various other nuclei and tracts. (NCI),NCI: The uppermost portion of the brainstem located betwee
