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.

DIA [1.3K]

Answer:

The missing options are:

a. "It's due to insufficient production of vitamin B12 in the colon."

b. "Increased production of intrinsic factor in the stomach leads to this type of anemia."

c. "Overproduction of vitamin B12 in the large intestine can result in pernicious anemia."

d. "Decreased production of intrinsic factor by the stomach affects the absorption of vitamin B12 in the small intestine."

The correct answer is d. "Decreased production of intrinsic factor by the stomach affects the absorption of vitamin B12 in the small intestine."

Explanation:

Intrinsic factor is a protein that is produced by cells in the stomach, this protein is essential for the absorption of vitamin B12 in the small intestine. Without intrinsic factor, the absorption of vitamin B12 would be really low, causing pernicious anemia since vitamin B12 is necessary for the production of healthy red blood cells. If there is not a good production of healthy red blood cells that can distribute O₂ and CO₂, the body suffers from pernicious anemia.

Colt1911 [192]

supporting the use of a racemic epinephrine nebulizer would be most effective in aiding bronchodilation in a child with laryngotracheobronchitis

The larynx, trachea, and bronchi become inflamed and swollen as a result of the viral infection known as croup. Nebulized racemic epinephrine is one type of treatment. The alpha-adrenergic substance known as racemic epinephrine. To minimize edema, it relies on mucosal vasoconstriction. This broadens the airways' lumen and improves air intake.

A nebulizer is a tool for delivering medications to the body in the form of a mist that is inhaled into the lungs. Nebulizers are frequently used to treat respiratory conditions such as asthma, cystic fibrosis, COPD, and others. They disperse liquids and suspensions into tiny aerosol droplets that are inhaled through the device's mouthpiece using oxygen, compressed air, or ultrasonic energy. A mixture of gas and solid or liquid particles is called an aerosol.
