Peristalsis in the Esophagus event triggers the opening of the gastroesophageal sphincter.
<u>Explanation:</u>
- In the esophagus, there are two types of peristalsis occurs.The first one is a "primary peristaltic wave" occurs through which bolus enters esophagus during swallowing.
- This "wave pushes the bolus down esophagus", into stomach in a wave lasting about 8–9 seconds.
- The esophageal sphincter in the lower region is separated by both sympathetic and parasymphathetic nerves.
- The pathways of vagal are a major for the relaxation of reflex of LES and this occurs in LES relaxations.
Answer:
<u>Ethanol prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u>
Explanation:
Ethylene glycol is an organic compound usually used in antifreeze solutions, solvents and cleaners.
It is abused during self-destruction and accidental intakes.
<u>In the body, ethylene glycol is acted upon by alcohol dehydrogenase and is converted into glycolate and oxalate.</u>
Glycolate and oxalate are both nephrotoxic/ kidney damaging substances. Oxalate precipitates calcium oxalate stones in the kidney. Ethylene glycol poisoning also causes high anion gap metabolic acidosis.
In order to prevent ethylene glycol poisoning, the patient is infused with ethanol, ethanol <u>prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u> In this way, ethylene glycol is not metabolized and the formation of nephrotoxic substances is prevented. Alcohol dehydrogenase instead reacts with ethanol to form acetaldehyde.

Explanation:
The Rosenhan experiment was conducted to evaluate the validity and reliability of psychiatric diagnosis. The experimenters feigned hallucinations to enter psychiatric hospitals and acted normally afterward.
The David Rosenhan study supported the claim that diagnosis of mental illnesses is often influenced by context and subjective evaluations.
Psychiatrists examined Rosenhan and others. They diagnosed them as mentally ill. As a result, Rosenhan concluded that it is not possible to distinguish between the sane and the insane in psychiatric hospitals.
