Some interesting facts about human bones.

Facts about human bones.

Bones:

Bones or bones are the rigid organs of vertebrates that form the endocarp. It helps the body to move (move), support and protect the various organs of the body, as well as the function of building red and white blood cells and storing mineral salts. The bones are of different sizes and shapes and are strong in weight but light. Their internal and external structures are complex. One of the main tissues of bone formation is called tissue called mineralized bone tissue, or just bone tissue, and provides bone stiffness and honeycomb three-dimensional internal structure. Other sorts of bone tissue include the marrow, endothelium and periosteum, nerves, blood vessels, and cartilage. An adult physical body has 206 bones while in infants 270 to 300 bones are found.

In this post we will talk about some unique facts of human bones. Bone or bone is an organ of any organism that gives shape and form to the body. It is exactly like a brick in the house, which gives the body a shape. All the bones are combined to form skeletons which helps in walking and doing other things. The main functions of the human skeleton are to shape the body, to help the body stand, to protect the internal organs, to help the body to move and most importantly to make new blood cells.

Bones are made up of calcium, phosphorus, sodium, other minerals and protein collagen.
At the time of man's birth, the total number of bones (bone and cartilage) in his body is 300, but with time many of these cartilages (soft bone) join together to form bone. On reaching puberty, the number of bones in a human body increases to 206. The weight of bones in humans is about 14% of the total body weight.
All bones have different size and shape. There is also no uniform division of bones in the whole body, some organs have more bones than other organs. For example, there are 106 bones in the hands and legs only, which is more than half of the total bones.
There are 27 bones in each hand, 26 bones in each leg. While the human skull has 22 bones. The spine is formed from 33 bones. While the face of a human is made up of 14 bones.
Each bone has an important character to function properly in the body. If a single bone is broken, then the bones around it also do not work properly.
Bones are joined together by joint. It is because of this joint that it helps in walking, turning and bending. There is bone marrow inside the bone, bone marrow looks like jelly, with the help of this, blood is made for the whole body. Above these bone marrow is the spongy bone, these spongy bones are also covered with a hard and strong bone. In this way a complete bone is formed.
Bone marrow makes 2 million red blood cells per second.
The bone located in the middle of the back is the spine or spine, with the help of this bone, the body can bend forward, back, side-by-side and can move in any direction. This bone supports the entire upper body.
The ribs located in the chest of human protect the lungs, heart, kidney and upper muscles of the body.
Human skull is also made up of many types of bones, many of these bones join together in childhood. The brain is protected in this skull and some design of this skull is made in such a way that there is empty space in it for the eyes and ears as well. There is only one moving part in the skull, that is the mandible of the lower jaw bone, none of the other bones move.
The hip bone connects the pelvis to the spine, its shape is like a bowl. Pelvis supports the spine supporting the upper part. During pregnancy, the ligament pelvis softens the bone and makes it slightly longer, so that the baby can fit comfortably in the womb. During pregnancy itself, such a process occurs, for which a special hormone, Relaxin, relaxin is responsible.
Like skin and hair, old bones continue to disintegrate and new bones continue to be formed, every 7 years, all the bones of the body gradually migrate from new bones.
Our bones are stronger than steel. A cubic inch bone can handle more than 19000 pounds. Pain caused by lifting more weight is due to muscles and other organs.
The strongest bone in the human body is the thigh bone femur and the weakest nose and spine. The largest bone in the human body is also the femur femur while the smallest ear bone is the stapes. Its size is equal to a grain of rice.
The knee joint is the largest joint in the human body. The three bones in the knee joint are femur, tibia and patella (femur, tibia, and patella). The joint of these three big bones becomes the largest joint.
Apart from one bone in the human body, all the bones are connected. The hyoid bone of the throat, which is the shape of the hoof of a horse, is a bone that is not connected to any other bone. This bone is found between the chin and therefore the Adam's apple . This bone is believed to be the biggest reason for voiding in humans, because where it is located, it works with both larynx and tongue. Through which many kinds of voices can be made in humans.
When we lift or bend our hands, feet or any other limb, it does not happen when ordering the bone. That is, to bend the limb, the brain does not send a signal to the bone. Rather, the brain sends messages to the muscles attached to the bones, then the muscles fold the entire limb along with the bone.
At the age of 20 to 30, bones are the most dense and strong, but with time the strength of bones decreases. Bone strength can be increased by eating calcium rich food and exercise. Sources of food such as dairy products, broccoli, fish, etc. can be used for calcium.
Our body is about 1 centimeter smaller in the evening than in the morning. The main reason for this is the cartilage found between the bones which shrinks due to standing and sitting from morning to evening.

When the fingers bend, it makes a crackling sound, why?

On twisting the joint of the fingers, there is a sound of its crackling, it is called finger chopping. The main reason for this is that some empty space is created in the joint of bones in which nitrogen gas bubbles are filled and when we click the finger, then this bubble bursts, we hear the sound of its burst. The same finger does not crack again at the same time, because when the bubble of nitrogen gas bursts, the empty space between the joints is filled and it takes time to bubble again.

The newborn baby does not have a knee cap which is also called patella patella. This cap normally starts appearing at 2–6 years of age. This is the reason that small children do not get hurt in their knees when walking.

How do broken bones join?

Our body attaches itself to a broken bone. However, plaster is applied on the limb for the broken bone to be connected properly and directly. A broken bone joins several stages. First of all, blood accumulates around the broken part and a crust is formed on the broken part. Then the tissue of this broken part, the collagen starts to grow and they join the cartilage together to break the broken head. This joint fills slowly and continues to strengthen until the bone is completely healed. It takes several months for a broken bone to heal. During the treatment of bone, there is no stress on it, for this, plaster is applied on that organ.

The bone that breaks the most is the hand bone. These bones are broken about half of the bones that break in adults. While the most broken bone in children is the collarbone.

America's stunt performer Evel Knievel has had the most broken bones in his body so far. According to Guinness book records, by the end of 1975, he had broken 433 bones in his body.
