Reuptake
They are called as vesicles. They are constantly created. They contents the neurotransmitter. Neurotransmitter is required for transmission of the nerve impulse.
The substance that is released at an axonal ending to propagate the nerve impulse to the next nerve or muscle is called
It is called a nerve impulse.

action potential
Reabsorption via a process called "secretion".
The neurotransmitters are stored in tiny sac-like structures called vesicles at the end of axons. When an impulse, or nerve signal, reaches the end of the axon, the vesicles release a neurotransmitter into the small space between the adjoining cells (synaptic gap). Neurotransmitters diffuse across the synapse and bind to receptors in the receiving cell that are specific for the neurotransmitter.
Well they are sent through the nervous system.
The impulse itself does not actually cross the gap, which is called a synapse by the way, instead it stimulates the realease of a neurotransmitter from vesicles. When the neurotransmitter reaches the other side of the synapse it binds proteins on the opposing membrane and in doing so stimulates the membrane to continue the action potential on the mect cell.
The point at which two neurones meet is called the synapse. At this point there are 2 situations:1: there is no gap, the neurones are physically connected by gap-junctions. This is a rarer situation but does occur. In this case the nerve impulse continues down the second neurone (known as the post-synaptic nerve)2: there is a small gap (a few micrometers) between the cells. In this case the first nerve, carrying the impulse, (pre-synaptic) causes a release of a chemical known as a neurotransmitter. There are various types of neurotransmitters and each are involved in different situations. When the neurotransmitter reaches the 2nd nerve it binds to the membrane (in most situations) which either causes the cell to depolarize and continue the impulse, or causes hypo-polarization which prevents any other nerve stimulating it.Short and Simple Answer:Nerve impulse is transmitted by:- nerve impulse triggers transmitter substance- which diffuses across synapse- the transmitter substance binds with receptor molecule in membrane of next molecule
Nerve messages are called an impulse. Synapses are the space between two axons.
The space through which a nervous impulse is transmitted from one neuron to another is called a synapse. It is a tiny gap between the axon of one neuron and the dendrite of another, where neurotransmitters carry signals across the gap to continue the message.
