The functional connection between two neurons is called the synapse. The location where the axonal termination of a nerve fiber that binds a close contact to the next nerve cell's dendrite is likewise called the synapse. The pre-synaptic knob is, in general, a pre-synaptic fiber that divides into numerous fine branches and ends in greatly stretched terminations. This makes contact with the post-synaptic cells. Based on electrons microscopy, these nerve cells at the synapse are divided by a synaptic cleft of several degrees wide. The transfer of impulse within the synapses is called synaptic transmissions.
When a muscle cell forms a synapse with a nerve cell, then it is called a neuromuscular junction. The cells which are responsible for sending the impulse are called pre-synaptic cells while the cell that received impulse is called post-synaptic cells. There are the two theories between the synaptic transmissions. There are dietary supplement such as the uridine that promote the smooth transmission of impulses from one cell to another than can be bought if you want to enhance the way your nervous system operates.
According to the Theory of Electrical Transmission, though the neurons are separate from each other, there is an effective local circuit connection which is found that allows enough current to pass from one nerve to another nerve through synaptic cleft. This type of transmission is found in carry fish giant motor synapse. There is a supplement that can be bought to enhance the function of the synapses.
According to the Theory of Chemical Transmission, as the nerve impulse reaches synapse, it activates to secrete a type of transmitter substance from the tip of the axon. This transmitter thing diffuses across the synaptic cleft and attaches itself to the special chemo-receptor on the surface of the dendrites of the next nerve cell. The combination of this chemical and the chemo-receptor leads to a change in the permeability of that membrane that depolarizes and sets up an action potential that is new. This nerve impulse or action potential passes along the total length of the neuron to the adjacent synapse where it is stimulated to again release the transmitter substance. The chemical transmission of the synapse involves two processes:
- Neurosecretion is when a nerve impulse reaches the axonal termination substance and is connected to the special molecular site in the dendrite. This produces a change in the permeability of the cell membrane so that a nerve impulse that is new is set up.
- Chemo-reception is the transmitter substance that is attached to a special molecular site in which the dendrite is located and then produces an alteration when it comes to the permeability of each cell membrane so that a new impulse is created.
The transmission of the nerve impulse across the synapse is normally both sympathetic and parasympathetic system. It takes place by the release of transmitter substance. In parasympathetic system, acetylcholine is released and those fibers are called cholinergic fiber. When a nerve impulse arrives at the motor end plate, the acetylcholine is released and then it transmits an impulse to the muscle fiber which starts the contraction action; after a short contraction, the nerve releases another chemical substance called acetylcholine esterase which breaks acetylcholine and causes the muscle fiber to normalize.
