The signal transmission process of the myoneural junction involves the following parts: axon terminals, pre-synaptic cell, synaptic cleft, receptors, and post-synaptic cell. Firstly, a nerve impulse will go to the axon terminals. Once it reaches the terminals, a molecule, called the neurotransmitter will be released. This neurotransmitter is stored in the pre-synaptic cell, which is attached to the axon terminals. For this process, the specific neurotransmitter ejected is called acetycholine or Ach. This Ach will then proceed to the synaptic cleft, the gap between the pre-synaptic cell (motor neuron) and the post-synaptic cell (muscle cell), and then bind to the receptors of the muscle cell.
Acetylcholine will diffuse and once adequate amount of Ach is ejected, the sarcolemma, or the membrane of the muscle cell, will be open to positive sodium (NA+) ions to enter the cell and positive potassium (K+) ions to be excreted out from the cell. Since NA+ enter more into the muscle cell than K+ leaving out of the cell, the sarcolemma will have a plethora of positive ions thus changing the electrical state of the sarcolemma causing it to have additional pathways solely for NA+ entrance. This occurrence would generate an electric current called action potential. When this current goes out of hand, the entirety of the sarcolemma would be conducted by electric impulses which results to muscle contractions. <span />

Answer:
Im way too nice for my own good lol
Explanation:
"The c****19 virus has affected me and my family harshly as we cannot go outside and not able to meet up with friends. My feelings about not returning to school are that i'm upset because i'm not able to have fun with my friends and laugh, in person at least. Technology has made the c****19 feel a lot better for many people because we can see friends and family virtually and can communicate with them as well. My feelings on wearing masks and gloves are mixed as I am not used to it but I know it will help to keep many other and myself safe. Staying home is not all bad though we can't go out as often and freely as we used to be able too, but staying home is good as well because if you like spending time with family, you will be able too, and a lot."
