Skull

The skull is a bony structure that forms the head of the human body. It consists of the cranium, facial bones, and mandible. The cranium houses and protects the brain while the facial bones support the sensory organs such as the eyes, nose, and mouth. The mandible, also known as the lower jaw, is the only movable bone in the skull and is responsible for chewing and speaking.

The skull is made up of 22 bones that are tightly joined together by sutures. The bones of the skull are classified into two groups: the cranial bones and the facial bones. The cranial bones include the frontal bone, parietal bones, temporal bones, occipital bone, sphenoid bone, and ethmoid bone. The facial bones include the maxilla, zygomatic bone, nasal bones, lacrimal bones, palatine bones, vomer bone, and inferior nasal conchae.

The skull is an important part of the human anatomy as it protects the brain and supports the sensory organs. Damage to the skull can result in serious injuries that may affect the brain and other parts of the body. Skull fractures, for example, can cause serious brain injuries that may lead to permanent brain damage or even death.

The human skull has evolved over millions of years to accommodate the growing size of the brain. The skulls of our early ancestors were smaller and more robust than modern humans. As the brain grew larger, the skull had to expand to accommodate it. Today, the human skull is relatively large and thin, reflecting the increase in brain size and the decrease in the strength and thickness of the skull bone.
