Neurotransmitters are special chemicals that are produced and stored in synaptic vesicles. There are many different kinds and each vesicle can hold hundreds of them. When they are released, they cross the synaptic cleft and attach to a receptor site which may be on another nerve cell, a muscle cell, or a gland.

What substance is found in synaptic vesicles of the axon terminal what role does it play in neurotransmissions?
Acethylcholine
What are the tiny sacs found within the terminal button which release chemicals into the synapse?
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of nerve cells.
What susbstance is found in synaptic vesicles of axon terminal?
Neurotransmiter, which may be Acetylcholine etc
The are sack-like structures found inside the synaptic knob containing chemicals?
synaptic vesicles
Where is neurotransmitter stored?
Neurotransmitters are stored in synaptic vesicles in the terminal bouton of pre-synaptic axons. They are released from the terminal bouton into the synaptic cleft and the neurotransmitters exert their action on the post-synaptic neurons.
Chemicals found in the synaptic vesicles which when released has an effect on the next cell?
a neurotransmitter
What are the criteria for a substance in a neurotransmitter at a synapse?
Criteria required identifying a substance as a neurotransmitter 1- ) Synthesis of the substance: • It is synthesized in the neuron • Some substances are synthesized from the Tryptophan • Rate limiting step in its synthesis • Enzymes required in the synthesis of that substance are themselves synthesized in the cell body of neuron ,then distributed throughout the neuron • Mainly found in the cell body and nerve terminal • These enzymes are stored in the presynaptic terminal of neuron, inside the synaptic vesicles. 2- ) Storage of that substance: • The neutransmitter is stored inside the synaptic vesicle of nerve terminal 3- ) Release of the neurotransmitter: • It is released from the nerve terminal usually through Ca++ dependent process following the stimulation of the nerve fiber by action potential. • Fusion of the synaptic vesicle with the nerve membrane releasing neurotransmitter outside the nerve fiber into the synaptic cleft. 4- ) Exogenous analogue (drug) of the neurotransmitter: • If drug analogue of the neurotransmitter is injected exogenously, it should mimic the same mechanism of action as done by the endogenously released neurotransmitter.
A chemical found in the synaptic vesicles that when released has an effect on the next cell is called a?
neurotransmitters
What is the terminal buttom?
the sack like structures found inside the synaptic knob containing chemicals are called what?
Which structure in the neuron receives information from another nerve cell?
Its the synaptic cleft found at the end of the axon terminal.
What term refers to a neurotransmitter?
are endogenous chemicals which relay, amplify, and modulate signals between a neuron and another cell.[1] Neurotransmitters are packaged into synaptic vesicles that cluster beneath the membrane on the presynaptic side of a synapse, and are released into the synaptic cleft, where they bind to receptors in the membrane on the postsynaptic side of the synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may follow graded electrical potentials. Low level "baseline" release also occurs without electrical stimulation.
