Luckily for us, the human skull is an incredibly strong and resilient structure. It serves as a protective armor, shielding our precious brain from harm. But just how strong is our skull? Can it withstand the force of a bullet or survive being crushed? Is it really stronger than concrete?
The bones of the skull can be considered as two groups: those of the cranium (which consist of the cranial roof and cranial base) and those of the face. In this article, we shall look at the anatomy of the bones of the skull – their orientation, articulations, and clinical relevance.
Frontal Bone. The frontal bone has two main parts: the squamous part and the orbital part. The squamous part is the large, flat area that makes up most of the forehead. The orbital part is smaller and lies horizontally, forming the top of the eye sockets and helping shape the nasal cavities.
The mandible is the strongest and largest bone of the face. The mandible forms the lower jaw and is the site of insertion for the lower teeth. The sphenoid bone is a butterfly-shaped bone consisting of a body, and upper and lower wings. The sphenoid bone contains the sphenoid sinuses.
The skull is one of the most vital bony structures of the human body, as it houses and protects the most important organs, including the brain. There are 29 bones (including the hyoid and middle ear bones) that comprise the skull and give shape to the head. The skull is divided into the neurocranium and the facial skeleton.
Two parts are more prominent: the cranium (pl.: craniums or crania) and the mandible. [2] . In humans, these two parts are the neurocranium (braincase) and the viscerocranium (facial skeleton) that includes the mandible as its largest bone.
The skull base comprises parts of the frontal, ethmoid, sphenoid, occipital and temporal bones. The facial skeleton is referred to as all skull bones anteroinferior to the cranial cavity. Prominent representatives are the maxilla (upper jaw) and the mandible (lower jaw).
It is the weakest part of the skull. The pterion is located approximately two finger widths above the zygomatic arch and a thumb’s width posterior to the upward portion of the zygomatic bone.
When done by region, the skull is classified by its two main parts: the cranium and the mandible. These two structures are not attached when there are no tendons or muscles holding them together.
What are cranial bones? Your skull provides structure to your head and face while also protecting your brain. The bones in your skull can be divided into the cranial bones, which form your...
