2. Neuron
• It is the basic structral and
funtional unit of Nervous system.
• Neurons are specialized to
transmit information throughout
the body.

3. Types of Neurons
Sensory Motor Interneurons

4. Motor Neuron
• Motor neurons carry signals from the
central nervous system to the outer parts
(muscles, skin, glands) of your body.
• If its axon terminal join with other neuron
it forms synapse, but if it join with muscles
or glands it form motor nerve end plate.
• Largest nerve cell in nervous system.
• Also called multipolar neuron because
numerous dendrites projects from cell
body, in multiple direction.

5. Motor Neuron Cont’d
• Deals with OUTGOING messages
from the brain/spinal cord to act
upon the outside world
• They have very long axons.

6. Sensory Neuron
• Sensory neurons carry signals from the
outer parts of your body (periphery) into
the central nervous system.
• Sensory neurons also called unipolar
neuron, bcz Dendrites and Axon terminal
arises from same axis.
• Also called AFFERENT Neurons
• Transmit impulses from the receptors in
our sense organs (the eyes, ears, skin, nose,
tongue and muscles, organs ) to the brain.

7. Pseudounipolar neuron
• Is a sensory neuron in the peripheral nervous system.
• Dendrites and Axon terminal arises from same stem.

8. Inter Neuron(associative neurons)
• Interneurons connect
various neurons within the
brain and spinal cord.
• Interneurons, carry
information between motor
and sensory neurons.
• Only found in the brain,
spinal cord, and eye.
• Easy to recognize – they
have short axons.
