The anatomical name for the canopy is parietal, or the skull, which consists of the frontal, temporal, parietal, occipital, pterygoid, and sieve bones, and is located at the top of the human cranium. The parietal is rounded and top-shaped, which protects the human brain and is one of the hardest bones in the human body. However, it exists in a position where it is vulnerable to injury, and if the parietal is damaged by the action of violent factors, it may show symptoms of paralysis, or even be life-threatening. When a baby is born, the skull at the top of the skull is not completely closed between the skull bones, and the space in between is called fontanel. The closure of fontanel is affected by the development of the skull and the brain, so it can be used as an important indicator of the development of the baby. Normal closure occurs between 6 and 18 months of age. If it is not in this range attention should be drawn to it and a visit to the hospital should be made. Diseases such as high blood pressure can cause pain in the fontanelle. If the patient experiences pain or a blow to the fontanelle, he or she should go to the hospital for examination and treatment.
