The main difference between the skull and the cranium is their location in the head. In addition, the cranium is the part that covers the brain. Skull is the skeletal structure which covers the head and the cranium and the face are the two components of it. The main function of the skull is to protect the brain, attach muscles of the face and determine the facial features while the main function of the cranium is to protect the brain, meninges and cerebral vasculature. Mandible, which is a bone of the skull, can be moved while the bones of the cranium are immobile. The skull is composed of 22 bones while the cranium is composed of 8 bones. Skull refers to the bone framework that encloses the head of a vertebrate while cranium refers to the part of the skull that encloses the brain. They also provide sites for the attachment of muscles responsible for the movement of the head, facial expressions, and chewing.ĭifference Between Skull and Cranium Definition.Their main function is to protect the brain.Most bones in the skull and cranium are made up of flat bones formed by intramembranous ossification.Skull and cranium are two skeletal structures of the head.The cranial base provides the articulation point for the atlas or the first cervical vertebra, facial bones, and the mandible. ![]() ![]() Cranial base – Made up of six bones frontal, sphenoid, ethmoid, occipital, parietal and temporal bones.Calvarium – Made up of the frontal, occipital, and two parietal bones.The two main parts of the cranium are roof or the calvarium and the cranial base. It protects the brain along with meninges and cerebral vasculature. The jaw bone, which is articulated with the base of the cranium at the temporomandibular joint (TMJ)Ĭranium is the part of the skull, which covers the brain. Located at the posterior wall of the oral cavityįorms a part of the upper jaw and hard palateįorms the posterior part of the nasal septum Occur within the nasal cavity, increasing the amount of air inspired The slender bones at the bridge of the nose The smallest facial bones and they form part of the medial wall of the orbit The cheekbones of the face they articulate with the frontal, sphenoid, temporal and maxilla bones The types of facial bones and their role in the skull are described in the table below. The fusing of the 14 individual facial bones houses oral and nasal cavities, the orbits of the eyes, and the hollow spaces called sinuses. The facial skeleton is also called the viscerocranium and it provides sites for the attachment of muscles of the face and determines the facial features. Hence, the total number of bones in the skull is 29. In addition, the ossicles of the ear and the hyoid bones are also considered as the bones of the skull. The cranium is composed of 8 bones while the face is made up of 14 bones. Cranium and face are the two main parts of the skull. These joints are immovable and they are completely fused together at the age of 20. It is composed of several bones made up through intramembranous ossification and joined together by fibrous joints called sutures. Skull is the protective structure of bones, which supports the face and hosts the brain. – Comparison of Key Differences Key TermsĬranial Bones, Facial Bones, Location, Role of the Bones, Skull, Sutures What is the Difference Between Skull and Cranium What are the Similarities Between Skull and CraniumĤ. The main function of them is to protect the brain and the other internal structures in the head. Skull and cranium are two terms used in describing the skeletal structures of the head. The main difference between skull and cranium is that the skull is composed of both facial bones and the cranium whereas the cranium is the upper part of the skull, composed of bones that do not move. Furthermore, the number of bones in the skull is 22, including 8 cranial bones and 14 facial bones, while the number of bones in the cranium is 8.
