The Human Brain

Homework: (It is very unclear so I will type out what is written on the diagram-starting from the very top label and working in a clockwise direction + with the noted functions of each section of the human brain) 

The human brain





Cerebral hemispheres- Composed of two parts of the cerebrum. The cerebrum is the part of the brain that is responsible for the integration (processing) of sensor and neural (relating to the nervous system) functions and the initiation of co-ordination and voluntary activity. 

Cerebellum-it is the part of the brain below the back of the cerebrum. It regulates balance, posture, movement and muscle co-ordination. 

Medulla oblongata- the lowest section of the brainstem, it controls automatic (involuntary-in other words it is not in our control) functions like heartbeat and breathing. 

Pituitary gland- it is an endocrine (relating to glands which secrete hormones into the blood system) glands about the size of a pea. It is a gland that is attached to the base of the brain and secretes hormones which are associated with homeostasis. 

Hypothalamus- the region of the brain that co-ordinates both the automic nervous system (part of the nervous system which cannot be controlled by us e.g heartbeat, breathing and digestion) and controls the activity of the pituitary gland. 

Corpus Callosum- a large bundle of nerve fibres that connect the left and right cerebral hemisphere's together.
