Health Assessment of Patients Quiz

C: Thyroxine or thyroid hormone contains iodine.

C: The acini cells produce digestive enzymes.

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

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

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.

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

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

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

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

C: The hypothalamus produces peptide hormones.

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

B: The anterior pituitary produces and releases six hormones.

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

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.
