Skull
The skull is a bony structure that forms the head in humans and other animals. It serves several critical functions, including protecting the brain, housing the sensory organs like the eyes, ears, and nose, and providing attachment points for muscles that control facial expressions and chewing. The skull is made up of multiple bones that are fused together, with the cranium and the mandible (jawbone) being the most notable parts.
Inside, the skull features cavities and foramina (small openings) which allow for the passage of nerves and blood vessels that connect the brain to the rest of the body. This complex structure also plays a crucial role in shaping a person’s appearance and voice. The shape and size of the skull can vary between individuals and are influenced by genetic and environmental factors.
Despite its toughness, the skull can be vulnerable to injury, so understanding its role and structure is essential. Maintaining good bone health is important for keeping the skull and the rest of the skeletal system strong throughout life.
