How does the nervous system work?

1. GROUP MEMBERS:
NERVOUS
SYSTEM

2. 5. The nervous system
The nervous system sends and receives information.
It coordinates the functions of internal organs. And
it also coordinates systems like the digestive
system.

3. The nervous system´s
PARTS The central nervous system consists of
Brain
Spinal cord
This system receives information,
interprets it and decide on a response.
The peripheral nervous system consists on
nerves. It transmits information from the sense

movements
The cerebellum
coordinates
movements and
maintains balances.The brain stem
regulates internal
organs.
The spinal cord controls reflex movements
6.The

response to external stimuli.
These
are the
result of
decisions

5. Neurons are the principal cells of the nervous system. They
receive and transmit information. They are grouped together to
form nerves.

8. The endocrine system
Responsible for
Functions such as
GROWTH REPRODUCTION

Glands
Consists of
They secrete substances called
hormones into the bloodstream
Thyroid gland
Enables the
body to
absorb
nutrients
Pancreas
Controls the
amount of
sugar in the

Ovaries and
testes
Responsible
for
