The subcellular structures of neuron that forms the basis for transmission of nerve impulses are the synapticvesicles.
What arethestepsinimpulsetransmissionbetweenneurons?
The action potential or nerve impulse reaches the <u>axon</u> of neuron and depolarises the membrane.
Voltage gated Calcium channels open .
Arrival of action potential causes the synaptic vesicle to attach to presynaptic membrane.
Calcium influx triggers release of neurotransmitter.
This neurotransmitters bind to postsynaptic membrane and new impulses are created.
Synaptic vesicle under resting condition:
The neurotransmitter molecules are stored in synaptic vesicles.
If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
During resting condition, they are placed randomly.
When an impulse reaches the axon, vesicles are arranged in the presynaptic membrane.
Thus from the above we can conclude that, synaptic vesicles are the subcellular structures in transmission of nerve impulses and , under resting condition they are placed randomly.
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units.
