A35-year-old male is diagnosed with a hormone-secreting tumor of the adrenal medulla. he experiences elevated blood pressure, pupil dilation, "goose bumps," and increased anxiety. which of the following hormones is the predominant one released by the tumor?
a.
antidiuretic hormone
b.
acetylcholine
c.
norepinephrine
d.
cortisol

c. Norepinephrine

Explanation:

Norepinephrine is a chemical compound of the catecholamine family, whose precursor is the amino acid tyrosine. Noradrenaline acts as a neurotransmitter and hormone and is an endogenous adrenaline precursor. It is produced in the adrenal medulla and also in the nervous system.

When it is in excess in the body, this hormone can cause increased anxiety, hyperactivity and high blood pressure. In addition, individuals with excess of this hormone usually have pupil dilation and constant chills. For this reason, we can conclude that the hormone being secreted by the man exposed in the question is Norepinephrine.

c.  Norepinephrine

Explanation:

A 35-year-old male is diagnosed with a hormone-secreting tumor of the adrenal medulla. He experiences elevated blood pressure, pupil dilation, "goose bumps," and increased anxiety. Therefore, Norepinephrine is the hormone that has the predominant one released by the tumor.
