PRIMARY CARE PROVIDER FINAL PAPER 2026
QUESTIONS WITH VERIFIED SOLUTIONS AND
EXPLANATIONS

◉ What Does the Thyroid Gland Do? Answer: The thyroid glands
function is to regulate the bodies metabolism


It produces three hormones:
• Thyroxine (T4)
• Triodothyronine (T3)
• Calcitonin


◉ Physiology of the Thyroid Gland Answer: The thyroid gland is
under control by the pituitary gland


When T3 and T4 are low the pituitary gland produces Thyroid
Stimulating Hormone (TSH)


TSH stimulates the thyroid gland to produce more T3 and T4

, The pituitary gland senses the rise of thyroid hormones in the blood
serum and decreases the TSH production


The pituitary gland is under control by the hypothalamus which
secretes TSH Releasing Hormone (TRH)


TRH tells the pituitary gland to stimulate TSH


◉ Physiological Effects of Thyroid Hormone Answer: There is no
particular target tissue for thyroid hormone


Every cell in body is affected by the thyroid hormones


Influence the metabolism of proteins, carbohydrates, lipids, cell
morphology, membrane transport, oxygen consumption and heat
production.


Thyroid hormones are required for normal growth and development


◉ Prevalence of Thyroid Disease Answer: Hypothyroidism is the
most common resulting from iodine deficiency due to diet


Autoimmune is the most common thyroid disorder in iodine-
replente areas of the world
