MICROANATOMY

Detailed explanation-1: -Another neurotransmitter dopamine that has limited actions in the autonomic nervous system may excite or inhibit depending on the receptors. Dopamine can be converted into norepinephrine and thus can increase heart rate and blood pressure.

Detailed explanation-2: -Epinephrine (Adrenaline) and Norepinephrine (Noradrenaline) Among other things, these hormones are capable of increasing the heart rate and force of heart contractions, increasing blood flow to the muscles and brain, relaxing airway smooth muscles, and assisting in glucose (sugar) metabolism.

Detailed explanation-3: -The adrenal glands produce too much of the hormone aldosterone. This makes the kidneys retain salt and water and lose too much potassium, which raises blood pressure.

Detailed explanation-4: -A sudden large increase in adrenal hormones is called an adrenergic crisis (AC). AC causes severe high blood pressure (hypertension) and a rapid heart rate (tachycardia).

Detailed explanation-5: -Your adrenal glands make the hormone adrenaline and send it into your bloodstream. Adrenaline, a hormone your adrenal glands produce, has a purpose. It helps you face dangerous situations by causing temporary changes in your body. Your heartbeats and breathing get faster as part of the “fight or flight” response.
