Question

Which of the following hormone is not correctly matched to its source?

• A. Adrenal cortex - Corticoids
• B. Adrenal medulla - Catecholamines
• C. Thymus - Thyroxine
• D. Parathyroid gland - PTH

Answer 1

The correct option is C Thymus - Thyroxine

Adrenal gland has 2 layers - Adrenal cortex and adrenal medulla. The adrenal cortex produces corticoids. They are of 2 main types glucocorticoid (cortisol) and mineralocorticoid (aldosterone). The adrenal medulla produces catecholamines called epinephrine and norepinephrine.
The thymus gland produces thymosin and the thyroid gland produces thyroxine. Parathyroid gland produces the parathyroid hormone (PTH).
