The consequences if presynaptic action potentials In an axon release insufficient acetylcholine to depolarize a skeletal muscle fiber to threshold

Explanation:

When an action potential reaches a neuromuscular junction, it causes acetylcholine to be released into this synapse. The acetylcholine binds to the nicotinic receptors concentrated on the motor end plate, a specialized area of the muscle fibre's post-synaptic membrane.

Acetylcholine is the neurotransmitter used at the neuromuscular junction—in other words, it is the chemical that motor neurons of the nervous system release in order to activate muscles. ... In the brain, acetylcholine functions as a neurotransmitter and as a neuromodulator.

It is important to address that boy may has exercise-induced asthma.

Exercise-induced asthma is a narrowing of the airways in the lungs triggered by strenuous exercise. It causes shortness of breath, wheezing, coughing, and other symptoms during or after exercise.

The more preferred term for this condition is exercise-induced bronchoconstriction.

Kids with EIB should be able to take part in activities; they just may need medication before an activity.

There are three types of medicines to prevent or treat the symptoms of EIB.

They are short-acting bronchodilator (taken 10-15min  before the activity), long-acting bronchodilator (taken 30-60min  before the activity) and mast cell stabilizers (taken 10-15min  before the activity).

When texting while driving, a man crashed into a red car in front of him and felt panic. Thereafter, whenever he saw red cars, h
kompoz [17]

Answer:

This is an example of a flashback, associating a red car with an event that the man found to be traumatic. It might also be an example of post traumatic stress.

Explanation:

The events surrounding a trauma can become imprinted in the psyche. In this case, the first image the man observed after the crash, was a red car. Cognitively, he knows that the red car was just an incidental item. Emotionally imprinted though, is the image of the red car. The unconscious mind observes the red car, and makes a connection, and brings about anxiety and heightened awareness. This reaction is designed to avoid further trauma and discomfort.

Misha Larkins [42]

In radiology and nuclear medicine, single - photon emission therapy (PET)/computed tomography (CT) scanning is now a standard practice.

<h3>What distinguishes a CT scan from a PET scan?</h3>

The internal organs and tissues of your body are depicted in great detail by a CT scan. A Pet / ct can be more accurate than some other imaging procedures and can detect aberrant activity. Additionally, it can cause your body to alter sooner. PET-CT scans are used by doctors to reveal more details about the cancer.

<h3>What distinguishes an MRI from a PET scan?</h3>

Radio waves and magnets are both used in magnetic resonance imaging (MRI) studies. Both generate static photos of the body's organs and skeletal system. Using a radioactive tracer, PET scans can demonstrate how an organ is working in real time. CT and MRI scans cannot identify cellular responses in tissues and organs as early as PET scan images can.
