that coordinate the actions and transmit signals between different parts of its body. The nervous system
consists of two parts, central and peripheral. The central nervous system is divided into two major parts:
the brain and the spinal cord. The peripheral nervous system consists of sensory neurons, clusters of neu-
rons called ganglia, and nerves connecting them to each other and to the central nervous system.
The brain The brain lies within the skull and is shaped like a mushroom. The brain consists of four principal
parts:
1) the brain stem;
2) the cerebrum;
3) the cerebellum;
4) the diencephalon.
The brain weighs approximately 1.3 to 1.4 kg. It has nerve cells called the neurons and supporting
cells called the glia.
There are two types of matter in the brain: grey matter and white matter. Grey matter receives and
stores impulses. Cell bodies of neurons and neuroglia are in the grey matter. White matter in the brain
carries impulses to and from grey matter. It consists of the nerve fibers (axons).
The brain stem The brain stem is also known as the Medulla oblongata. It is located between the pons and the spinal
cord and is only about one inch long.
The cerebrum The cerebrum forms the bulk of the brain and is supported on
the brain stem. The cerebrum is divided into two hemispheres.
Each hemisphere controls the activities of the side of the body
opposite that hemisphere.
The hemispheres are further divided into four lobes:
1) Frontal lobe;
2) Temporal lobe;
3) Parietal lobe;
4) Occipital lobe.
