Answer:
The correct answers are: Neurotransmitter Vesicles, Acetylcholine, Contraction.
Explanation:
- At the neuro-muscular junction, impulses are transmitted in the following manner:
- The impulse is carried by an action potential (variable opening and closing of different ion channels located on the membrane of the neurons allowing variable ion movement) to the neuron at the neuro-muscular junction.
- The action potential causes the opening of the voltage dependent calcium channels in the axon terminal of the neuron allowing the entry of calcium ions.
- This causes the neurotransmitter vesicles containing the neurotransmitter acetylcholine to fuse with the pre-synaptic membrane.
- Acetylcholine is released by the method of exocytosis into the synaptic cleft.
- The acetylcholine molecules bind to the the cognate receptors present in the membrane of the muscle cell (sarcolemma).
- This causes the flow of sodium ions into and potassium ions out of the muscle cell, which generates action potential in the muscle cell.
- This action potential causes the muscle cell to contract.

Nonpreemptive kernels have a single active process at a time. Therefore, race situation scenarios are not possible in nonpreemptive kernels. If preemptive is properly designed to ensure that shared kernel data is devoid of race circumstances, it is race-free.
An illustration of a race condition is when a data structure updates a list of open files in a system when a new file is closed or opened. In this scenario, opening two files simultaneously would cause the list to receive two separate updates, which could lead to race situations.
<h3>
Difference between preemptive and nonpreemptive kernaals ?</h3>
It is a procedure that might be immediately changed. In comparison to non-preemptive kernels, it is more suited for real-time programming. Preemption is typically permitted, even in kernel mode. Responsive time is deterministic and is more responsive as compared to non-preemptive kernel.
It is a process that keeps running indefinitely until it has handled all execution handlers or willingly gives up the CPU. Compared to a preemptive kernel, it is less suited to real-time programming. Preemption of kernel mode processes is typically not allowed. In comparison to a preemptive kernel, response time is less responsive and nondeterministic.
