Skull in situ Human head skull from side Anatomy of a flat bone – the periosteum of the neurocranium is known as the pericranium Human skull from the front Side bones of skull. The human skull is the bone structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain. Like the ...
A fractured cribriform plate (anterior skull trauma) can result in leaking of cerebrospinal fluid into the nose and loss of sense of smell. The tiny apertures of the plate transmitting the olfactory nerve become the route of ascent for a pathogen, Naegleria fowleri.
In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan, [1] [2] is the upper and back part of the skull, which forms a protective case around the brain. [3] In the human skull, the neurocranium includes the calvaria or skullcap. The remainder of the skull is the facial skeleton.
The calvaria is the top part of the skull. It is the superior part of the neurocranium and covers the cranial cavity containing the brain. It forms the main component of the skull roof. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. [1]
The pre-colonial standard of beauty among these groups were of broad faces and receding foreheads, with the ideal skull dimensions being of equal length and width. The devices used to achieve this include a comb-like set of thin rods known as tangad, plates or tablets called sipit, or padded boards called saop. These were bound to a baby's ...
The crista galli (Latin: "crest of the rooster") is a wedge-shaped, vertical, midline upward continuation of the perpendicular plate of the ethmoid bone of the skull, [1] projecting above the cribriform plate [2] into the cranial cavity. It serves as an attachment for the membranes surrounding the brain. [1]
The cranioplasty material is placed on the defect and is fixed to the surrounding skull with standard titanium plate and screws. CSF may be drained from the brain to reduce herniation. Small holes may be drilled on the bone graft or the prosthesis to prevent the accumulation of fluid under the repaired defect.
Another general agreement is the avoidance of the use of titanium plates in the fixation of the skull. [ 64 ] [ 65 ] One potential complication following this procedure involves the gradual movement of the titanium plates towards the brain, induced by resorption of the innermost bone layer of the skull with deposition of new bone on the ...
