THIS REFER BY THE ESSENTIALS OF MEDICAL PHYSIOLOGY BOOK (SIX EDITION) HELLO! I AM MEET DESAI. STUDENT OF A PHYSIOTHERAPY. THIS IS MY COLLEGE PROJECT . I'M SHARING TO STUDENT LIKE ME.. THIS AVAILABLE MY LINK LIKE..https://www.linkedin.com/in/meet-desai-18296b178 THANK YOU SO MACH .TO SEE

1. NEUROTRANSMITTER

2. INTRODUCTION OF THE NERVES
SYSTEM:
• Nervous System Of The Body.
• There are a parts of nervous system.
A. Central Nervous System
B. Peripheral Nervous System

3. NERVOUS SYSTEM
1. Brain
2. spinal cord
1. Autonomic Nervous system
A. Sympathetic
B. parasympathetic
2. Somatic Nervous System

6. • NEURON Also called a nerve cells
• Is as the and unit
of Nervous System.
There are a main parts of the nerve cells
I. Cell Body
ii. Dendrite
iii. Axon
01
NEURO
N

8. Cross Sections Of a Nerve

9. Synapse
• Synapse Is The Between Two Neurons.
• Is The “ ” Between The Axon Of One Nerve And The
Dendrite Of The Next One

13. INTRODUCTION:
• Neurotransmitter are the that communicate
information by our brain and body.
• The brain uses neurotransmitter to tell ,
and .
• They can also affect and
can cause when they are out of

14. NEUROTRANSMITTER ...............
is a That acts as a for the transmission of nerve from one neuron
to another neuron by a
DEFINITION:

15. branching fiber that from other
neuron
ddsfsff
Are the
point
where
the axon
Is a thin fiber where is
from the neuron to other neurons
This is a NEURON

16. TRANSPORT AND RELEASE OF NEUROTRANSMITTER:-
a neurotransmitter.
• and to the .
• AT. the ,the neurotransmitter is in small it
called a .
• then,vesicle and the nurotransmitter into .
• it to on the surface of the .

18. Transmision
• It travels by the Axon
• come from soma
• from the pre - synapti terminal
• to the next neuron
• it re-uptake sometime occure

19. 1. it must be found in neuron.
2. produce by a neuron
3. released by a neuron
4. after,it must be act on a target area and produce some biological
effect
5. after the action it must be Inactivated
CRITERI FOR NEUROTRANSMITTER:
Many substances are categorise.to consider a
neurotransmitter

20. CLASSIFICATION OF NEUROTRANSMITTER:
• DEPENDING UPON THE CHEMICAL NATURE
1. Amino Acids
2. Amines
3. others

21. . Amino acid
• This group are involved in and are
inhibitory and excitatory in action.
• EXAMPLE :
GABA (gamma aminobutyric acid), Glycine , glutamic acid , aspartate
acid

22. . Amines
• Amines are the .
• that involv in .these
neurotransmitter are also inhibitory and excitatory in action.
• EXAMPLE:
Noradrenaline , adrenaline , dopamine , histamine

23. 3. others
• some neurotansmitter do not fit into any of these categories.
• one such substance is .
• othe substance include in this category is the soluble gass
( )

24. DEOENDING UPON THE FUNCTION:
 There are two type ..
1. Excitatory nurotransmitters
2. Inhibitory neurotransmitter

25. EXCITATORY NEUROTRANSMITTER:
 Action potential down of another .
 Release of .
of on cell membrane .
of ligand gate .
 flow of in the cell.
 cell become .
 Leads to a .
 Known as a .
Examples:-
 Acetylcholine
 Histamine
 Norepinephrinr

26. INHIBITORY NEUROTRANSMITTER:-
 Actionof Inhibitory neurotransmitter.
 action potential of another nerve
cells.
 releases of neurotransmitter.
 Activation of on cells .
 opening of .
 flow of of cells.
 Lead to .
 Known as .
 Example:
• GABA
• Dopamine

27. EXCITATORY AND INHIBITORY NEUROTRANSMITTER:-
EXCITATORY NEUROTRANSMITTER:
INHIBITORY NEUROTRASMITTER:
NEUROTRANSMITTER WITHE BOTH ACTION:
1. Acetylcholine 1. GABA 1. Noradrenaline
2. nitric oxid 2. glycne 2.adrinaline
3. Histamine 3. dopamine
4.aspartate 4.serotonin

28. IMPORTANT NEUROTRANSMITTER:-
 Acetylcoline
 Noradrenaline
 Dopamine
 Serotonin
 Histamine
 GABA
 Nitric oxide

29. 1.ACETYLCHOLINE:-
 Is a .
 it possesses .
 source:
- Preganglionic parasympatheic nerve
- Post-ganglionic parasympatheic nerve
- Preganglionic Sympathetic nerve
- many region of brain
- Postganglionic Sympathetic cholinergic nerves
 there are a types of
receptors...
1.
2.

30. 2. NORADRENALINE:-
 Noradrenaline is the neurotransmitter in
.
 it released....
1. Postganglionic Sympathetic nerves ending
2. cerebral cortex
3. Hypothelamus
4. basal ganglia
5. brainsten
6 .spinal cord

31. 3. DOPAMINE:-

1.Basal Ganglia
2.Hypothalamus
3.Limbic system
4.Retina
 It action is a .

32. 4. SEROTONIN:-
 Large amount of serotonin( %) is found in
of .
 small amount found in and .
 its secreted...
1.hypothalamus
2.Limbic system
3.cerebellum
4.Midbrain
5.GI tract

33. 5. HISTAMINE:-
 Is secreted in nerve e ending of , ,
and other part of the .
 it also secrete by the and .

34. 6.GAMMA- AMNOBUTYRIC ACID(GABA):-
 Its a inhibitory neurotransmitter in synapses particular in .
 secreted .....
1.cerebral cortex
