Hello you all Here is @Munna ktk with you.. From many days i have posted a lot about photography and nature so lets change something..and today going to talking about
spinal cord...........................!!!
The spinal cord is the largest and strongest bone in the body on which the other bones and structures of the body depend. It is not really a bone, but a chain of bones that is about 27 inches long in a young man, and this chain consists of 33 regular bones. The so-called spinal seals have three parts. The first body, the second two horizontal branches and the third spinal branch. The core of the spinal cord is made up of 34 different bones that are tied to each other in such a way that they have flexibility and we move our backs back and forth. You can bend wherever you want. It is also easy to jump, run and bend. There are four elbows in this chain which makes it easy to carry the load on the back. If there is a shock, its effect does not reach the brain. The chest and abdominal cavities become larger.
Improper walking or sitting can cause a spinal cord bend in children, which can lead to poor physical condition and poor bone strength. The seven spines of the spine are in the neck. The twelve spines are joined to the ribs in the thoracic region. Five pieces are in the waist, five are between the hip bones and four or five are in the very lower part.
These bones are connected in such a way that their holes fit right into each other and all these holes together form a long groove called the spinal canal. It actually contains the spinal cord which is a part of the brain. From where the nerve veins on both sides come out and go to the muscles of the hands and feet.
There are many holes on both sides of the spinal cord for these veins. Only one nerve vein can come out of a hole. 34 such pairs emerge from the nerve veins and reach the hands and feet on both sides. Therefore, the spinal cord has 34 holes on both sides which are formed by the meeting of bones.
