At the end of the year, after fierce ideological struggle and sufficient preparation, you finally summon up the courage to walk into the boss’s office and want to talk about the salary increase with the boss. But somehow, the boss’s office is like a magic spell! Although you have made sufficient preparations, as soon as you enter, your heart will unconsciously start to beat faster and feel uneasy.
Nervous is nervous, but you have more clearly explained the reason why you want a raise to your boss than usual, and the boss also agreed to your request. A burst of ecstasy, success!
There are many such examples. Athletes will feel their hearts beating faster and their faces turning red at the critical moment of the competition, when police officers are chasing fugitives, and even when they encounter male gods and goddesses at this critical juncture and do not know what to say. However, they will also feel that they are extremely quick in thinking or can use forces that cannot be imagined at ordinary times.
All this is closely related to the adrenal gland, the transmission of the human body.
What is the adrenal gland
Normal adults have one adrenal gland on the left and one on the right, which is located above our human kidney and may weigh only 8-10g. The adrenal gland on the right is triangular and the adrenal gland on the left is half moon-shaped, like two orange hats, [worn] on our kidney.
Therefore, the adrenal gland is also called [accessory kidney].
However, don’t be fooled into thinking that the adrenal gland, like the kidney, is the composition of the urinary system. In fact, the adrenal gland is a real endocrine organ and a large factory that produces endogenous hormones.
Important Accelerator for Human Body
About 10% of the tissue that occupies the most central part of the adrenal gland is called adrenal medulla, and chromaffin cells in it secrete some important endogenous hormones, collectively referred to as catecholamines, including dopamine, epinephrine and norepinephrine.
In a state of stress, That is, when Wu Song meets tigers, athletes meet match points, and police uncles capture fugitives, Due to the regulation of visceral nerves, catecholamines secreted by adrenal glands will increase sharply in a short period of time. These catecholamines act on muscles and blood vessels, which can accelerate the heart rate, enhance the blood pumping function of the heart, increase systolic blood pressure, raise blood sugar and dilate pupils, thus enabling the human body to better cope with extreme situations.
Therefore, adrenal medulla can be said to be an important accelerator for human body under stress.
Some people have grown cells with pheochromocyte function in adrenal gland or parts other than adrenal gland due to disease reasons, which are clinically called pheochromocytoma. Such patients may have sharp fluctuations in blood pressure and blood sugar and arrhythmia, requiring timely treatment and treatment.
An extremely important rescue drug
Japanese scholar Gao Feng Jean Ji discovered long ago that adrenal gland extract from cattle and other animals can accelerate human heart rate and other manifestations, and further discovered epinephrine and invented the purification method of epinephrine.
For modern medicine, exogenous catecholamines as drugs are also extremely important:
- Adrenaline: An important rescue drug, which is extremely important in the treatment of cardiopulmonary resuscitation and anaphylactic shock. Norepinephrine and dopamine: Important booster drugs are also extremely important in treating critically ill patients.
Most [hormones] are in the adrenal cortex
The adrenal cortex, which occupies more than 90% of the volume of the adrenal gland, has a wider effect.
1. We often say [hormone] refers to glucocorticoid
First of all, the adrenal cortex secretes a large amount of glucocorticoids. Many people have heard of the need to use [hormones] when treating certain diseases, and their components are often similar to those secreted by the human body itself.
Although glucocorticoids may cause harm to human body in excess, They are essential to sustain life, It is widely involved in the metabolism of sugar, fat, protein and electrolyte, and has important regulatory effects on human growth, maintenance of blood pressure and hematopoiesis, and has the effects of inhibiting immunity and anti-inflammation. This is also the basic reason why doctors can use glucocorticoids to treat patients with specific diseases.
