The skull is composed of cranial bones that form the brain's vault and facial bones that give origin to facial muscles and protect the brain. Except for the temporomandibular joint, bones are connected by generally immovable fibrous sutures. The orbit contains 7 bones and is home to the eye and related structures. The external nose is largely cartilaginous. The hyoid bone supports the tongue muscles. There are 24 ribs total, with 12 true ribs directly connecting to the sternum and 12 false ribs indirectly connecting or floating. The pelvis contains the acetabulum cavity for the femur head, and distinguishes male from female skeletons. The document discusses skull, orbit, hyoid, ribs,
