Answer:
In chemical transmission the release of chemical messengers known as neurotransmitters occurs. Neurotransmitters carry information from the presynaptic or transmitter neuron to the postsynaptic or recipient cell.
As you may recall from the article on the structure and function of the neuron, synapses are usually formed between the nerve terminals - axon terminals - of the sending neuron and the cell body or dendrites of the receiving neuron.
Scheme of synaptic transmission. An action potential travels through the axon of the presynaptic or emitting cell, and reaches multiple axon terminals branching from the axon. The axon terminal is adjacent to the dendrite of the postsynaptic or recipient cell. This place of close connection between axon and dendrite is the synapse.
A single axon can have multiple ramifications, which allows it to synapse with several postsynaptic cells. Similarly, a single neuron can receive miles of synaptic inputs from many different presynaptic or emitting neurons.
Within the axon terminal of a transmitter cell there are many synaptic vesicles. These are membranous spheres full of neurotransmitter molecules. There is a small space between the axon terminal of the presynaptic neuron and the postsynaptic cell membrane, this space is called synaptic space.

</u>
Explanation: The nerve cells are also termed as neurons. Their structure is quite from other kinds of cells. These consist of long and slender region called as axon, with branches at one end, called as dendrites and a head region on the other end, called as cell body. The structure is shared below.
The axon region is covered with mylein sheath, throughout the region except few gaps, which act as the points from where action potential jumps and pass from one neuron to another.
Hi!
So there is a need for scientific names, and I'll tell you why.
Scientists and researchers need to have a "universal language", so they can communicate with others around the world. They use scientific names that normally have Latin origins.
The reason we use common names is so people <em>don't </em>get confused. Normal people won't go around saying they need to walk their canis lupus familiaris. They'd say they need to walk their dog.
Hope this helps ya out fam!

Answer:
Moreover, the way that this works is that convection currents in the mantle causes tectonic plates to move when material near the Earth's core rises, and colder mantle rock sinks. Hot magma wells up at the ridges, forming new ocean crust and shoving the plates apart.
