However, with the development of modern anatomy and X-ray examination technology, it is found that some bones will regenerate extra "accessory bones" or "daughter bones". If you count "accessory bone" or "daughter bone", there are far more than 206 adult bones. For example, some people have 24 "accessory bones" and "daughter bones" in each hand and wrist, and 26 in each foot. Sometimes, small bones grow on the knees, elbows and spine of the body. And everyone has different extra bones.
These "extra little bones" are of little significance, as long as you know that adults have 206 bones.
Of course, it is not absolute to say that adults have 206 bones, which is based on the "whole" of human beings all over the world. There are differences between people. A sample survey conducted by scientists in China in 1985 shows that China people have fewer bones than Europeans and Americans. Most people in our country only have 204 bones. The same is true of the Japanese survey. In Europe and America, most people have 206 bones, and only a few people have 204.
Which two bones are missing in China and Japan than in Europe and America? At first, it was generally believed that there were three bones in the fifth toe, but now it is found that there are two bones in China and Japan. Because each foot lacks 1 bone, there are only 204 bones. Other answers *** 10 206 There are 206 adult bones, which are divided into four parts: skull, trunk bone, upper limb bone and lower limb bone. But the child's bones are much bigger than others, because the child has five sacrums, which will be 1 when he grows up. Children have 4 ~ 5 coccyxes, and adults have 1. The child has two ilium, two ischium and two pubic bones, which merge into two hip bones in adulthood. In this way, children have more bones than adults 1 1 ~ 12, which should actually be 2 17 ~ 2 18. According to medical books, newborn babies have as many as 305 bones.
