Health Assessment of Patients Quiz

C: The acini cells produce digestive enzymes.

B: Aldosterone causes reclamation of sodium ions from the filtrate and potassium to be secreted in exchange.

C: Steroids are lipid soluble so diffuse through the plasma membrane to bind to a receptor within the cell.

A: Thyroid hormones T3 and T4 contain three and four iodine atoms, respectively.

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

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

C: Thyroxine or thyroid hormone contains iodine.

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.

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

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

A: PTH increases plasma Ca2+ (calcitonin aids in lowering blood calcium).

B: Testosterone is not produced in the pituitary nor does the pituitary contain autonomic centres.

B: Parafollicular (or “C”) cells of the thyroid produce calcitonin which aids in lowering of blood calcium.

C: The hypothalamus controls the secretion of the anterior pituitary by the use of “releasing hormones” and “inhibitory hormones”.

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