The brain is dominated by the cerebral hemispheres.
Their highly convoluted outer mantle consists of grey matter; the inner core of white matter.
The hemispheres are separated by the great longitudinal fissure.
THE BRAIN STEM.
Midbrain – most superior part of brain stem.
Pons – anterior projection of the brain stem, above medulla oblongata.
Medulla oblongata – meets the spinal cord, lowest part of the brain stem.
This mass carries nerve fibres between the medulla, pons, midbrain and cerebellum.
The outer layer (cerebral cortex) consists of grey matter.
Cortex surface is highly convoluted, forming a regular pattern of narrow parallel folds or folia.
The central core consists of white matter, nerve fibres running to and from the cortex.
Tree like arrangement.
Cerebellum is responsible for coordination of movement on an entirely unconscious level.
