Drag the labels onto the table to indicate which type(s of gated ion channels are found in each membrane associated with a chemical synapse. (the letters in the table refer to the lettered structures in the image above. labels can be used once, more than once, or not at all.

Chemical synapses send and receive information by transmitting information from one cell to another. The processes involve are presynaptic and postsynaptic transmission, respectively. For instance, the neurons of the nervous system transmit neurotransmitters as ion channels to the next cell through the synaptic cleft. The presence of the different gated ion channels determine the distribution of the chemical synapse involve for each neurotransmitter. 

Synapses are the meeting point between the axon terminals found in one neuron with another neuron.

Synapses are formed by swollen axon terminals. In the nervous system, synapses are structures that allow neurons (nerve cells) to pass electrical or chemical signals to other cells (or vice versa).

Neurons are excited cells or cells that can be electrically stimulated. Functioning as a method by which these cells can communicate with other cells. At synapses, the plasma membrane of the signal then moves past neurons (presynaptic neurons) and enters the apposition close to the target cell membrane (postkasynapsis).

Composition of synapses, consisting of:

There are 5 functions of synapses, including:

Exciting synapses

This type of synapses is the transmission of information that has a stimulating effect and facilitates postsynaptic neurons in order to realize the potential for action and transmission of messages to continue while producing membrane depolarization.

Synapsis inhibition

Actuation or activation of this type of synapses can inhibit the appearance of action potentials with postsynaptic cell hyperpolarization so that it becomes more difficult for information transmitted through postsynaptic neurons to others associated with it.  

In chemical synapses, the potential for action affects other neurons through gaps between neurons called synapses. Potential for action is a shift in the electrical potential of neurons caused by the flow of ions in and out of the nerve membrane. Potential actions can trigger chemical and electrical synapses. Synapses consist of the presynaptic end, the synaptic cleft, and the postsynaptic end. When an action potential is produced, it is carried along axons to the presynaptic end. This triggers the release of chemical messengers called neurotransmitters. These molecules cross the synaptic cleft and bind to the receptor at the end of the postsynaptic dendrite. Neurotransmitters can excite postsynaptic neurons, which causes them to produce their own action potential. Or, they can inhibit postsynaptic neurons, in which case they do not produce an action potential. Electrical synapses can only excite. They occur when two neurons are connected through a gap junction. This gap is much smaller than synapses and includes ion channels that facilitate the direct transmission of positive electrical signals. As a result, electrical synapses are much faster than chemical synapses. However, the signal decreases from one neuron to the next, making it less effective in transmitting.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
