Solution
The correct option is B Thyroxin
Adrenaline hormone is secreted by adrenal medulla. It is secreted in response to stressful and emergency situations and are called emergency hormones or hormones of fight or flight. It It increases dilation of blood vessels, heartbeat, the strength of heart contraction and the rate of respiration. It also increases alertness, pupillary dilation, piloerection (raising of hairs), sweating etc. It also stimulates the breakdown of glycogen resulting in an increased concentration of glucose in blood. In addition, they also stimulate the breakdown of lipids and proteins.
ACTH is adrenocorticotropic hormone which is synthesised and released by anterior pituitary. It stimulates the synthesis and secretion of steroid hormones called glucocorticoids from the adrenal cortex.
Thyroxin hormone is secreted by follicular cells of the thyroid gland. It has major role in regulating the basal metabolic rate of the body.
Calcitonin hormone is released by parafollicular cells or C cells of thyroid gland. It has role in regulating the calcium metabolism of the body along with parathyroid hormone.
