Health Assessment of Patients Quiz

A: Epinephrine is derived from the amino acid tyrosine (so tyrosine is a wrong answer).

D: Aldosterone promotes the absorption of sodium from the filtrate, while potassium (also a positively charged ion) is secreted to maintain electrical neutrality.

C: Thyroxine or thyroid hormone contains iodine.

B: The anterior pituitary produces hormones that stimulate other endocrine organs, but the anterior pituitary does not release hormones until directed by the hypothalamus.

D: Beta cells of the pancreatic islets produce insulin. The alpha cells produce glucagon.

C: The hypothalamus produces peptide hormones.

C: As aldosterone is concerned with the absorption of sodium ions, a_x000d_“mineral”, and aldosterone is produced by the adrenal cortex; it is termed a mineralocorticoid.

C: The acini cells produce digestive enzymes.

D: Hypothalamus secretes regulatory hormones that control endocrine cells in the anterior pituitary gland, produces ADH and oxytocin and contains “autonomic centres” that exert neural control over endocrine cells of the adrenal medullae.

B: ADH and OT are produced in the hypothalamus and transported to the posterior pituitary.

C: Thyroxine (or tetraiodothyronine) is converted to triiodothyronine in_x000D_target tissues.

C: PTH causes increased calcium absorption and hence increases blood calcium level.

As steroid hormones are lipid soluble, their receptors are inside the cell as they can cross the plasma membrane.

D: Endocrine glands secrete “circulating” hormones, that is, they are secreted into the blood.

D: The pituitary gland releases peptide hormones which are soluble in blood. The other choices refer to steroid hormones which are insoluble in blood. They require transport via plasma proteins.
