Bone age according to hand X-rays
Bone age is a conditional age corresponding to the level of development of a child's bones. It can be established by means of an X-ray examination.
Special X-ray tables exist that summarize the normal bone age of children and adolescents.
Testosterone is the male sex hormone, which is essential for the creation of female sex hormones, i. e. female sex hormones are only obtained by conversion from male ones.
Testosterone is synthesized in the ovaries and adrenal glands and has a great need for women. At the beginning of the cycle, under the influence of FSH, it begins to change into estradiol. So, if you didn't have male sex hormones, you wouldn't have female ones either.
In addition, male sex hormones are responsible for your libido and temperament in general. In other words, male sex hormones are pretty crucial for a woman, but only in moderation.
Where does blood originate in humans?
In humans, blood is formed from about 30,000 hematopoietic stem cells, mostly in the bone marrow, but also in the small intestinal peyere plaques, thymus, lymph nodes, and spleen.
A branch of medicine called hematology studies the blood.
The ovaries resemble two tiny oblong masses averaging 3 × 2 cm in size and whitish in color
The ovaries features with two functions: to produce female sex hormones and to grow eggs. In fact, it is in the process of growing eggs that these hormones are produced.

In the body of an average person with a healthy microbiome, there are commonly about 1,000 various species of intestinal bacteria, nearly 300 species of bacteria living in the mouth, 850 species of skin bacteria and several dozen to several hundred bacterial species that inhabit the genitourinary tract
And that's not counting viruses, microscopic fungi and parasites that are also part of our microbiome.
What are the most proteins in the body?
From 25 to 35% of our body's proteins are collagens. They form the basis of connective tissue and ensure its elasticity and strength: such as, the organic bone matrix is 90% collagen of the first type. There are a total of 28 types of collagens, which are encoded by 40 genes.
For the human body, the reproductive system is the most redundant under tough conditions
This mechanism has biological expediency. If the brain evaluates the body's condition as "bad", it shuts down the most unnecessary for survival at the present moment — the reproductive system.
Collagen is the main building protein
It is what holds cells tightly together, enveloping them like a mesh.
Collagen is filamentous, allowing it to perform this function in the best possible way.
By the way, it is the lack of this protein that causes early wrinkles☝🏻
After all, collagen provides elasticity to skin, ligaments, vascular walls and even nails!

Take a look at the world through the eyes of a surgeon
And figure out what weird "sights " they see☝🏻
To do so, we need to clarify one point.
Modern surgeries are performed by laparoscopy — it doesn't involve any incisions.
Only three tiny punctures for a special camera and two, no less special, instruments.
That's how we get the "view" out of the camera 📷
And the metal "thing" is one of those tools.
Naturally, the video is only animation, not actual footage from the operating room.
The future is here and it's scary!
Today we can become half cyborgs, print food on a 3d printer, and live in a revolving skyscraper. It's real!
