Human Anatomy/Osteology/Skull Quiz

Skull Anatomy Quiz Test. Before starting the quiz about skull-anatomy, couple of things needs to be discussed. The English word "skull" is probably derived from the Old Norse "skulle", while the Latin word cranium comes from the Greek root κρανίον (kranion). To make the definition easy to understand- The skull is a bony structure that forms the head in vertebrates. It supports the structures of the face and provides a protective cavityfor the brain. The skull is composed of two parts one of them is the cranium and another one is mandible. In humans, these two parts are the neurocraniumand the viscerocranium or facial skeleton that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalization-housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans, these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localization of the direction and distance of sounds. In some animals such as horned ungulates, the skull also has a defensive function by providing the mount (on the frontal bone) for the horns. The skull is made up of a number of fused flat bones and contains many foramina, fossae, processes, and several cavities or sinuses. In zoology, there are openings in the skull called fenestrae. Now it’s time to answer those quizzes.
