HOW DO YOU KNOW THAT ARE CONSCIOUS?
HOW DO YOU THAT YOU ARE NOT DREAMING

HOW DO YOU KNOW THAT YOU KNOW?

As human being we are constantly interacting
with our environment, either directly or
indirectly…..
We are able to identify and respond to them in a
way because of specific organs in our bodies..
People are able to analyse their environments
and get answers to some questions regarding
their own unique behaviours..

All human beings are essentially biological
entities , therefore, we need to understand our
biological structures, how our bodies function,
and gain the inside into how these affect our
behaviours….

Western (1999) posited that human behaviour
depends on complex information processing
which takes place in the nervous system..
“The nervous system is the interacting network of
nerve cells that underlies all psychological activity.
The fact is , we talk, smile, eat , think, feel, cry, be
emotional and even the simples of actions all
form part of a very complex process…….

CELLS OF THE NERVOUS SYSTEM =
-Glial cells and
- Neurons

Glial cells:
- They are more abundant than neurons
- They give the structural support to neurons and
glue or hold them in place..
- They regulate the environment of the neurons
and clean up the dead cells (Debris)…
- They form myelin sheath around neurons ,
which enables them to prevent circuiting and
activates the level of information processing….

Neurons:
- They are also called the nerve cells
- They are reckon as the basic elements of the
nervous system…
- Their main function is to receive, integrate and
transmit information in our bodily system..
- They communicate with one another
electrochemically…….

Types of neurons
Afferent neurons (Sensory),
–relay information from the senses to the brain and spinal cord.
•Eyes, ears, nose, mouth, and skin...
