Hello friends today I am going to share with you (Human Skeleton) 206 Bones Name List PDF free book If you are a student of science then it becomes necessary for you that you have complete knowledge about human body, and if you are a student of biology then it is more important for you to know about 206 bones of human. so Today we have given here with you an image of 206 human bones, by reading which you can collect complete information.
There are about 206 to 213 bones in the human skeleton. There are 300 bones in the skeleton of a child. Our body has 300 bones at birth but later it reduces to 126 bones in the axial skeleton and 126 in the appendix skeleton. Some bones fuse as a person ages. And this process of aka utilization usually continues within three decades of this life, so the number of bones in any individual can be assessed separately.

There are total 206 bones in an adult human body. Their structures are of different types, and it is only because of these bones that the human body is able to stand. When a child is born, at that time there are 270 bones in his body, but later it decreases to 80 bones in the axial skeleton and 126 bones in the appendix skeleton.
Human body is made up of 50% water and 50% solids, the weight of bones is 14% of our body weight.
- The longest bone found in the human body is the femur, which is about 19.9 inches in length, which is also commonly known as the life bone. Only by looking at his thigh, it can be inferred that the femur is the longest bone. It extends from the hip down to the knee area.
- The smallest and lightest bone in the human body is the stapes, whose length is up to 11 inches. It is present here between our ears. There are three bones in the middle ear which is one of the smallest bones in the human body.
