Click and look at the illustration to remind yourself of
the main structural and functional divisions of the
nervous system, from:
http://aspenbishopfamnet/images/CNS2jpg
Remember that these divisions are mostly for
convenience --- for us to understand how our body
parts work, because there is inter-connection
between the nerves of the PNS, our sense organs
and sensory receptors, the effectors and the two
parts of the CNS.
Remember too, that the structures of the CNS and
PNS work with the hormones of the endocrine
system to control and regulate all our life processes
and body functions.

NOTE : You see the figure on the cover slide
spinning and changing directions because of
what your brain is trying to do.
Your brain receives ‘information’ from nerve
impulses sent from receptors in your eyes to the
visual area, temporal lobe and other brain
centres, and it is interpreting those nerve impulses
based on prior observations and information that
it has stored.
But, the figure has nothing surrounding/near to it,

The Peripheral Nervous System (PNS)
The peripheral nervous system consists of cranial nerves
that are connected to the brain and spinal nerves that
originate from the spinal cord.
There are twelve pairs of cranial nerves that come from
the brain and ennervate the body directly, without
passing through the spinal cord. Some important
cranial nerves that you’ll encounter later are: the
olfactory (sensory fibres from nose) and optic (sensory
fibres from the eyes). The vagus (wanders all over the
body, with sensory fibres especially to the heart, lungs,
and visceral organs and also motor fibres to other
areas).
Thirty one (31) paired spinal nerves pass out of the
cord, connecting the spinal cord to sense organs,
muscles and glands in all parts of the body.

3. What is a Neurone?
A neurone is a nerve cell. It has 3 main parts: the
dendrites, the cell body and the axon.
There are other sections of the neurone and each plays
a role in its overall function which is to transmit nerve
impulses between various parts and the CNS.

INTRODUCTION
3. What is a neurone?
Transmission of impulses
A neurone or nerve cell receives and transmits nerve
impulses in one direction only along its fibre (axon).
When a neurone is not sending impulses, it has what
is called a resting potential and it has a slightly
negative charge inside of it.
When a neurone is to transmit nerve impulses, it
develops an action potential which is moved or
propagated along the axon automatically.
An action potential is an electro-chemical process;
the impulse travels along the fibre by electrical
means, till it reaches the synapse which is a space
forming the junction between two neurones.

REVIEW & QUIZ
INTRODUCTION
3. What is a neurone?
Transmission of impulses
An action potential cannot cross the synapse between
neurones, so, the action potential stimulates the release of
chemicals called neurotransmitters which diffuse across
the synaptic gap and eventually initiates another electrical
action potential.
Once the impulse starts in the next neurone, enzymes break
down the neurotransmitter. In this way, nerve impulses can
travel only in one direction at a synapse.
Look at the video clip at -
http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/huma
So, the nerve impulse is carried electrochemically: by
electrical means - i.e. nerve impulses, as well as by
chemical means i.e. neurotransmitters at synapses.

Once the impulse starts in the next neurone, enzymes
break down the neurotransmitter. In this way, nerve
impulses can travel only in one direction at a synapse.

A nerve is an ‘information pipeline’ between the CNS and
various tissues and organs. Each nerve is made up of the
axons or nerve fibres of many neurones. Within the nerve
there are blood vessels.
21
Sets of neurone fibres are
encased in a connective
tissue tube, forming a bundle.
Within each nerve are a number

4. Are nerves the same as neurones?
A nerve can be purely sensory, or purely motor or it can be
mixed. Most nerves in the body are made up of both
sensory and motor fibres.
Motor nerves contain only nerve fibres from motor or
effector neurones. They carry messages from the brain to
muscles to make various body parts move.
What kind of fibres would you expect to find in a sensory
nerve?
22
A Sensory nerve would contain only nerve fibres from
sensory/receptor or afferent neurones, carrying messages
to the CNS from receptors in different parts of the body
about the stimulus of pain, light, pressure, sound etc.CHECK

SUMMARY
1. Click and read from this website:
http://downloads.bbc.co.uk/schools/gcsebitesize/audio/science_
The nervous system enables us to respond to and survive in our
environment. It is made up of nerve cells called neurones
and is organized into two main sections – the CNS and
PNS .
The brain and the spinal cord interpret the nerve impulses
they receive from receptors and ‘instruct’ effectors to
produce changes called responses.
Parts of the brain perform specific functions.
2. Watch:
http://www.youtube.com/watch?v=oGjaP_bO37I&NR=1&feature
Sense organs have receptors whose impulses are converted to
responses called the senses.
