As with other higher vertebrates, the human nervous system has two main parts: the central nervous system (the brain and spinal cord) and the peripheral nervous system (the nerves that carry impulses to and from the central nervous system). In humans, the brain is especially large and well developed.

3. Nervous
system
It is a highly complex part of
an animal that coordinates its
actions and sensory
information by transmitting
signals to and from different
parts of its body.

4. Neurons are the structural and
functional units of the nervous
system.
They transmit electrical
signals, called nerve impulses.
Glial cells provide support
for neurons.

5. Structure of
Neuron
soma (cell body),
the axon (a long slender projection
that conducts electrical impulses
away from the cell body),
dendrites (tree-like structures that
receive messages from
other neurons), and
synapses (specialized junctions
between neurons).
The primary components of
the neuron are the

6. Function of
Neuron
Neurons (also known as neurones,
nerve cells and nerve fibers) are
electrically excitable cells in
the nervous system that function to
process and transmit information
Neurons are the core components of
the brain, spinal cord and peripheral
nerves..

7. Types of
Neuron
sensory neurons,
motor neurons, and
interneurons.
There are three major types
of neurons:

All three have different
functions, but the brain
needs all of them to
communicate effectively with
the rest of the body (and vice
versa).

8. Simplified schema of
basic nervous system
function: signals are
picked up by sensory
receptors and sent to the
spinal cord and brain,
where processing occurs
that results in signals
sent back to the spinal
cord and then out to
motor neurons
