This gap is called the synapse. The neurotransmitter crosses the gap, binds to a protein (receptor) on the muscle-cell membrane and causes an action potential in the muscle cell. The action potential rapidly spreads along the muscle cell and enters the cell through the T-tubule. The action ...
Thus, the action potential (nerve impulse or nerve signal) gets transmitted (propagated) down the nerve cell. There are a few things to note about the propagation of the action potential. When an area has been depolarized and repolarized and the action potential has moved on to the ...
Having survived a sinking of his ship in the North sea, a marriage that separated him from his two kids and two cross country journeys to find another job fixing machines, I think he wanted an easier path for his new child s. That being said, when I first introduced to my new “broth...
How does the nerve impulse cross the synapse? Electroencephalography A number of scientists thought that there might be a chemical that was produced by the nerve impulse. This chemical would cross the synapse and produce a nerve impulse in the next neuron. But how could that be proved? A ...
Historically, glia has been considered as an accessory cellular compartment helping neuronal cells in their "noble" functions, chiefly nerve impulse transmission and synaptic communication. Over the last ten years, the concept of a tripartite synapse including the contribution of astrocytes to the ...
