Brain from below
The brain is the part of the central nervous system that is located in the cranium. It consists of the two cerebral hemispheres, the brainstem (encephalic trunk) and the telencephalon, divided into interbrain (diencephalon), midbrain (mesencephalon), hindbrain (metencephalon) and afterbrain (myelencephalon). The illustration also shows the cerebral arterial circle as well as cranial nerves.
