Select the hormone of adrenal cortex which is responsible for hyperglycaemia.

Solution:

Cortisol is a glucocorticoid hormone secreted by the adrenal cortex. Glucocorticoids play a crucial role in maintaining blood glucose homeostasis. They stimulate gluconeogenesis (synthesis of glucose from non-carbohydrate sources), lipolysis (breakdown of fats), and proteolysis (breakdown of proteins), all of which contribute to increasing blood glucose levels, leading to hyperglycaemia. Aldosterone is a mineralocorticoid from the adrenal cortex, primarily involved in electrolyte balance. Epinephrine is secreted by the adrenal medulla, not the cortex, and also causes hyperglycemia. Sex corticoids are also produced by the adrenal cortex but are not primarily responsible for hyperglycemia.
