Huvudkapseln

Huvudkapseln, also known as the skull capsule or cranium, is the part of the skeleton that forms the head. It is composed of 22 bones, including the skull base and the facial skeleton. The skull base, which forms the base of the cranium, consists of several bones that fuse together in adulthood, including the ethmoid, sphenoid, occipital, and temporal bones. The facial skeleton, which forms the face, includes the maxillae, mandible, zygomatic bones, nasal bones, and others.

The skull capsule serves several important functions. It protects the brain and other vital structures within the head, such as the eyes and ears. It also provides attachment points for muscles that control facial expressions and movements of the head and neck. The skull capsule is divided into two main parts: the neurocranium, which houses the brain, and the viscerocranium, which houses the sense organs and facial structures.

The skull capsule is a complex structure that plays a crucial role in the overall function and protection of the head. Its bones are connected by sutures, which allow for some degree of movement and growth during childhood. In adulthood, most of these sutures fuse, providing stability and strength to the skull. The skull capsule is an essential component of the human skeleton, contributing to both the structure and function of the head.
