GENERAL HISTOLOGY

Detailed explanation-1: -epinephrine, also called adrenaline, hormone that is secreted mainly by the medulla of the adrenal glands and that functions primarily to increase cardiac output and to raise glucose levels in the blood.

Detailed explanation-2: -It is well known that epinephrine increases the strength of contraction and the heart rate.

Detailed explanation-3: -The sympathetic nervous system (SNS) releases the hormones (catecholamines-epinephrine and norepinephrine) to accelerate the heart rate.

Detailed explanation-4: -It plays a role in metabolism, attention, focus, panic and excitement. Abnormal levels are linked to sleep disorders, anxiety, hypertension and lowered immunity. Epinephrine’s major action is in its role as a hormone. Epinephrine is released by your adrenal glands in response to stress.

Detailed explanation-5: -Epinephrine increases aortic pressure during chest compressions via alpha-adrenergic constriction of arterioles, which increases pressure in the proximal aorta. Increased aortic pressure may shunt more blood into the coronary arteries and increase the probability of ROSC.
