“Shen Du Jun, why did you get rickets if you are good?”
“Shen Du Jun, why do you have rickets when you have rickets?”
What is rickets? Where did the symptoms come from?
Where there is any doubt, there is Shendujun. Today, Shendujun will tell you the core secret of rickets. Baba, are you ready? “Pathogenesis of Rickets”, let’s go!
To explain rickets clearly, we have to start with the bones.
The function of bones in the human body can be summed up in four phrases.
Supports the body, completes activities, protects internal organs, and stores minerals such as calcium and phosphorus.
Look for a long bone to study, the outermost thin membrane is < /span>periostium. Numerous vasculature and nerves, < /span>vasculatureis the conduits that deliver nutrients to the bones,nerves Responsible for finding FEEL, oh, it hurts here!
Into the main body, the outer layer of the main bone is strong and tightly packedbone tissue , like a high-density compressed plate, which is medically calledcompact bone. compact boneinward, honeycomb-likecancellous bone strong>.
Deep readers should talk about how bones can be stored This function of minerals such as calcium, phosphorus.
The concentration of calcium, phosphorus in human blood is always maintained. Within a certain range, it is medically called blood calcium balance.
When there istoo much calcium in the blood, the body stores a little more Calcium is in bones;
when in the bloodCalcium deficiency,skeletonremove the stored calcium and throw it in In the blood, ensure that the calcium concentration in the blood is within a reasonable range.
Let’s think about the human skeleton as a building.
Facing the Bone Building, Shen Du Jun digs a brick to show you-Bone cells, the bone building is made up of thousands of bone cells.
Bone cells are attached to the outsidecollagen fibers, you can understand, span>Bone cellsThe whole body is covered with a layer of steel mesh.
bloodpasses osteocytes,osteocytes will grab calcium, phosphorus in the blood to eat.
Calcium, PhosphorusAfter being absorbed and absorbed by bone cells, and then secreted again, it becomes a baby. Attached to bone cells that layer of steel mesh.
After a period of deposition,bone cellsare so packed with minerals that Bone mineralization process.
What about rickets?
Ricketsis actually blood calcium, Phosphorus likemineral deficiencies can do big things.
bloodcalcium, phosphorus strong>insufficiency,bone cellscannot get enoughcalcium, phosphorus span>, the steel mesh of the Bone Building will not be able to complete the mineralization.
On the other hand, bones also store the < strong>calcium, removed and thrown into blood to ensure calcium concentration in blood.
There is a lot of tossing here and there, but the Bone Building is thin, small, crooked, and has become a dangerous building that does not meet the standard.
What are the symptoms of rickets?
InfancyBone throughout the body is developing rapidly, such as span>Skull, Rib, Femur, etc.
Insufficient supply of calcium will affect the development of bones, which will lead to a series of symptoms.
If it affectscraniumdevelopment, it can result inSkull softening, and even “square skull” in severe cases.
If it affectsthoraxDevelopment, resulting in skeletal deformities, a string of protrusions will be seen along the rib, forming “ span>Rickets Beaded”.
If it affects the development of lower extremity bones, it is easy to appear< strong>Bone bends, forming“O” legsor“X” legs.
“Shen Du Jun, why is this good baby deficient in calcium? Can calcium treat rickets? What is the relationship between the onset of rickets and vitamin D?
Those who are anxious and restless, don’t worry.
The next episode, Shen Du Jun, will continue to unlock the truth about rickets for you. “Video”, remember to like and forward!
