Today we are going to learn five super facts about a skull fact. Number one, did you know that your skull is not just one big bone? It’s actually made up of 22 separate bones that are connected together. Eight of these bones form the cranium, which protects your brain. The largest of these is the frontal bone, which makes up your forehead. The other 14 bones make up your face, including the zygomatic bones that create your cheekbones and the nasal bones that shape your nose. These bones work together to give your face its unique structure and appearance.
Fact number two, when babies are born, their skull bones are not yet fully fused together. This is because the soft spots cold nels allow the baby’s head to change shape during birth and provide room for the brain to grow. Babies have two main nels, the anterior nel located on the top of the head, and a posterior nel found at the back of the head. As children grow older, these nels close and as skull bones gradually fused together by the age of two, most nels are closed Facts Number three, all the bones in your skull are connected and don’t move except for one, the lower jaw bone, also known as mandible.
This bone is connected to the rest of the skull through a pair of joints, cold, temporal, mandibular joints, or tmj, which are located just in front of your ears. The mandible allows you to open and close your mouth, talk and chew your food. It also holds your lower teeth and plays a crucial row in shaping the lower part of your face. Fact number four, the skull has special openings for nerves and blood vessels. These are several holes in your skull called for a min, which allow nerves and blood vessels to pass through.
For example, the large opening at the base of the skull called the Forin Magnum is where the spinal cord connects to the brain. Other smaller forin, such as the optic canal and a superior orbital fis allow nerves responsible for vision and eye movement to pass through these openings ensure that the brain and other structures within the skull received in necessary nutrients and signals to function properly. Fact number five, as you grow up, your skull changes shape to accommodate your growing brain and facial features. This process is cold remodeling and it continues throughout your life.
Although it slows down as you reach adulthood during childhood, the bones of your skull grow and thicken and the sutures which are fibrous joints connecting the skull bones gradually fuse. As you age, some bone loss may occur leading to changes in the shape and appearance of your face. I hope you enjoyed my five super facts melt skull. See you soon.
