Short / Long answer type questions.
Write briefly about the endocrine gland which helps combat stress.

Answer 1

Adrenaline and noradrenaline are hormones that help combat stress. They are secreted from the adrenal gland.

Our body has one pair of adrenal glands, one at the anterior part of each

kidney. The gland is composed of two types of tissues. The centrally located tissue is called the adrenal medulla, and outside this lies the adrenal cortex. The adrenal medulla secretes two hormones called adrenaline or epinephrine and noradrenaline or norepinephrine.

The adrenal cortex can be divided into three layers, called zona reticularis (inner layer), zona fasciculata (middle layer) and zona glomerulosa (outer layer). The adrenal cortex secretes many hormones, commonly called as corticoids. The corticoids, which are involved in carbohydrate metabolism are called glucocorticoids. In our body, cortisol is the main glucocorticoid. Corticoids, which regulate the balance of water and electrolytes in our body is called mineralocorticoids. Aldosterone is the main mineralocorticoid in our body.
