Acetylcholine is released by axon terminals of the motor neuron.
A critical event that occurs at the neuromuscular junction is the release of acetylcholine from the motor neuron's axon terminal. This neurotransmitter binds to receptors on the muscle membrane, leading to depolarization of the muscle cell and generation of an action potential, initiating muscle contraction. Dysfunctions at the neuromuscular junction can lead to diseases like myasthenia gravis.
binding of acetylcholine to membrane receptors on the sarcolemma
The release of acetylcholine at the neuromuscular junction is not considered a hormonal event because it involves the transmission of a neurotransmitter (acetylcholine) between nerve cells and muscle cells, which occurs locally and rapidly. Hormones are typically produced by endocrine glands, circulated through the bloodstream, and have slower and longer-lasting effects on target cells throughout the body.
Probability of an event is how many times it occurs.
In Chapter 4, a significant event occurs when the protagonist faces a pivotal challenge that tests their resolve and character. This moment often serves as a turning point, leading to critical decisions that shape the narrative's direction. The consequences of this event also deepen the relationships between characters and highlight key themes of the story.
Annual event
If an event keeps on occurring that means the event is at least annual. If it occurs more than once a year that makes the event perennial or biannual if it only occurs twice.
The time at which an event occurs.
If you mean annual event, it occurs yearly.
The change in atomic number after an alpha decay event occurs is a decrease of 2.
Define your event as [A occurs and B does not occur] or as [A occurs and B' occurs] where B' is the complement of B. Equivalently, this is the event that [A and B' both occur].
