The brain together with the spinal cord
is called the central nervous system. The encephalon is all parts of the central nervous system which are located in the cranium. It includes the brain, the cerebellum
, and brainstem
. The brain consists of two hemispheres and is the largest part of the encephalon. It allows, among its many functions, the reception, transmission, and analysis of information, hormone
regulation, and gland control. The cerebellum has other roles such as the coordination
of movement and balance. The brainstem, meanwhile, is responsible for regulating the activity of the heart and lungs. The encephalon is covered by a membrane, meninges, which has a protective role.
