Human Skeleton Model (Human Specimen Model)

There are 206 human skeleton models, which are divided into 4 parts: skull, trunk, upper limb and lower limb. Among them, there are 29 skull bones, 51 trunk bones, and 126 four femur bones. Due to the different positions and functions of bones in various parts of the human body, their shapes are also varied, which are called long bones, short bones, flat bones and irregular bones.

But children have more bones than adults. This is because: Children have 5 sacrums, which become 1 when they grow up. Children's coccyx has 4 to 5 pieces, and it is also synthesized into 1 piece when they grow up. Children have 2 ilium, 2 ischium, and 2 pubic bones, which merge into 2 hip bones in adults. In this way, children have 11 to 12 more bones than adults, that is, 217 to 218 bones. Medical books say that a newborn baby has as many as 305 bones.

However, some bones regenerate "auxiliary bones" or "sub-bones". For example, some people have 24 "auxiliary" and "sub-bones" in each hand and wrist, and 26 in each foot. Occasionally, additional small bones grow in the knees, elbows, and spine of the body. If "melted bones" or "sub-bones" are counted, there are far more than 206 bones in adults. But since these "extra bones" don't mean much, we just need to know that adults have 206 bones.
