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. Choose correct option for adrenal medulla:

(i) The adrenal medulla secretes adrenaline or epinephrine and noradrenaline or norepinephrine.

(ii) Hormones of adrenal medulla are commonly called as catecholamine.

(iii) Adrenaline and noradrenaline are rapidly secreted in response to stress of any kind and during emergency situations.

(iv) Catecholamines increase alertness, pupillary dilation, piloerection and sweating.

(v) Epinephrine and norepinephrine decreases heartbeat, strength of heart contraction and rate of respiration.

(vi) Adrenaline and noradrenaline responsible for glycogenolysis, lipolysis and proteolysis.

(vii) Catecholamines are hypoglycaemic hormone.
