The nervous system
- It is divided into the Central Nervous System (CNS)
and the Peripheral Nervous System (PNS).
- CNS: consists of the brain and the spinal cord. This is
where all the complex processing of information is done
and decisions are made.
- PNS: consists of the ganglion and nerves.
It brings information from the CNS and
transmits this information to the
muscles and glands.
- CNS: consists of the brain and the spinal cord. This is

and decisions are made.

- Human nervous system
- The brain is the center of awareness. It is divided into
two hemispheres. The cortex is more developed in
humans than in all other animals.
- The spinal cord is an extension of the brain.
It transports messages to and from the
brain to the peripheral nervous system. It is
also responsible for reflexes.
- The parts of the brain are: the frontal lobe, the parietal lobe, the occipital lobe,
the temporal lobe, the spinal cord and the cerebellum.
- Somatic Nervous System (SNS): receives information from the senses and transmits it to
the CNS. It also transmits information from the CNS to direct movement of muscles.
- Autonomic Nervous System (ANS): responsible for vital functions such as heart beat, breathing,
digestion. It transmits information to and from the internal body organs such as the liver and the lungs.
It operates automatically, involuntarily.
- The sympathetic nervous system stimulates
function like digestion. It is involved in 'the
fight or flight response'.
- to make homeostasis.
- to make homeostasis.
- The parasympathetic nervous system
slows functions like digestion. It is
involved in 'the fight or flight response'.
