Health Assessment of Patients Quiz

C: The acini cells produce digestive enzymes.

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: Thyroxine or thyroid hormone contains iodine.

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

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

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

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

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

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

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

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.

B: The anterior pituitary produces and releases six hormones.

A: Catecholamines (adrenaline, noradrenaline), dopamine and thyroid hormone are all derived from tyrosine.
