Where is the natural anti-bone?

Anti-bone refers to occipital bone, also known as posterior mountain bone, which is located at the back of skull and is a flat bone with concave inside and convex outside.

The central foramen is called the foramen magnum, through which the cranial cavity communicates with the spinal canal. The front of the foramen magnum is the base, the sides are the sides, and the occipital scales are at the back. The base is connected with the sphenoid body forward and upward. There is an oval protrusion on the outside of the lateral part, which means that the occipital condyle and the atlas form the atlanto-occipital joint. There is a hypoglossal nerve tube above the condyle, through which the hypoglossal nerve passes. The occipital scale constitutes the lower part of the posterior cranial fossa, and there is an external occipital protuberance at the lower part of the middle part of its external surface, which extends to both sides as the nape line, and trapezius muscle is attached to it.

In modern society, anti-bone has become a symbol of courage to create and quick thinking. There is a saying that there is a bone in the head, and there is nothing in Wan Li. In the hit drama "Famous Works through the Ages", Li Da's skill is anti-bone, which is called strange bone by fortune tellers. If it comes out 500 years later, it will be a great achievement in the future. Even if he can't ascend to the throne, he is also a generation of princes. According to Fengyunzi's method: there is an anti-bone in the back of the head, and you can enter the exam later. Some people call a rebellious head treason.
