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

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

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

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

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 .

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

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

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

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

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

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
( )

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

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

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

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
