The effect of adrenaline, injection is effective

Many people have experienced symptoms such as lack of strength all over the body, so they choose to go to the hospital for examination. After the doctor conducted various tests, it was finally discovered that an injection of adrenaline was needed. Many people feel very troubled when this happens because they don't know much about adrenaline. So what are the effects of injecting adrenaline?

1. Adrenaline receptor blockers can block adrenaline receptors and thus antagonize the effects of noradrenergic neurotransmitters or adrenaline receptor agonists, including α receptor blockers and β receptor blockers. When α receptor blockers are used in combination with adrenaline, they can reverse the pressor effect of adrenaline into a hypotensive effect. The short-acting α-receptor blocker phentolamine is very effective. The adrenal gland is an extremely important gland among the endocrine glands in the human body and is closely related to the gonads. In addition to synthesizing and secreting adrenal cortical hormones, the adrenal glands also secrete small amounts of sex hormones (androgens, estrogens, and progesterone). Excessive or insufficient secretion of adrenal cortex hormones will have adverse effects on the development of gonads and sexual organs, testicular spermatogenesis, ovarian ovulation and conception.

2. Adrenaline increases the heart's contractility; the blood vessels in the heart, liver, tendons and bones dilate, and the blood vessels in the skin and mucous membranes constrict. Medicinally, the adrenal glands are used to stimulate the heart in cardiac arrest or to dilate blood vessels in asthma. Guidance: It can strengthen the heart's contractility, increase excitability, accelerate conduction and increase cardiac output. The effects on blood vessels in various parts of the body vary not only in strength, but also in contraction or relaxation. It has a constrictive effect on the blood vessels of the skin, mucous membranes, and internal organs such as the kidneys;

3. The adrenal glands are very important endocrine organs in the human body. They are named adrenal glands because they are located above the kidneys on both sides. There is one adrenal gland on each side, located above the kidney, and both are wrapped by renal fascia and adipose tissue. The left adrenal gland is crescent-shaped, and the right adrenal gland is triangular. The two sides weigh a total of 10-15 grams. When viewed from the side, the gland is divided into two parts: the adrenal cortex and the adrenal medulla. The surrounding part is the cortex and the inner part is the medulla. The two are different in occurrence, structure and function, and are actually two endocrine glands.
