Brain:

• The human brain is a highly specialized organ that controls the body's activities.
• The forebrain, midbrain and hindbrain are the three primary units of the human brain.
• The human brain comprises soft tissues having more than a billion nerve cells that continuously send information to the internal and external environment.

The parts of the brain these structures belong to, along with their functions, are given in the table.

Structures	Part of Brain	Functions
Medulla Oblongata	Hindbrain	It regulates heart rate, blood pressure, breathing and many other involuntary functions.
Hypothalamus	Forebrain	It contains regulatory centres for thirst, hunger, water balance, body temperature and blood pressure.
Olfactory lobes	Forebrain	It transmits the sense of smell from the olfactory epithelium to the temporal region of the cerebrum.
Pons	Hindbrain	It coordinates the motor or muscular functions of both sides of the body.
Parietal lobes	Forebrain	It regulates sensory information and contains centres for touch, taste, pain sensation, pressure and temperature and some components of speech.
Cerebrum	Forebrain	It regulates the temperature and movements of the body.
Cerebellum	Hindbrain	It maintains body balance.
Temporal lobe	Forebrain	It controls hearing, smelling and recollection of audio-visual events and some components of speech centers.
