Calvarium
The calvarium, also known as the cranial vault or skullcap, refers to the superior part of the skull, encompassing the cranial bones that enclose and protect the brain. It's primarily composed of the frontal, parietal, and occipital bones, along with portions of the temporal and sphenoid bones. This protective structure is crucial for safeguarding the delicate neural tissues from external impacts, providing structural support, and forming the upper boundary of the cranial cavity. The calvarium's sutures, or fibrous joints, allow for some degree of flexibility during infancy and childhood, accommodating brain growth.
Calvarium meaning with examples
- During the forensic investigation, the forensic anthropologist carefully examined the calvarium for signs of trauma, hoping to determine the cause of death. The presence of a fracture would indicate that the victim had suffered some type of head injury before their death and would potentially help determine the victim's identity.
- In neurosurgery, precise incisions through the calvarium are often necessary to access and operate on brain tumors or aneurysms. The surgeon must take great care during the craniotomy not to damage the underlying dura mater or the delicate structures of the brain itself. This ensures minimal blood loss.
- Radiologists utilize CT scans and MRIs to visualize the calvarium, allowing them to diagnose fractures, infections, or abnormal growths within the cranial vault. These diagnostic images assist in the proper evaluation and treatment. The doctor looked at the scan for signs of blood clots.
- Paleontologists study the calvarium of fossilized hominids to understand the evolution of the brain size and shape. Measuring cranial capacity and analyzing its features provide insights into the cognitive abilities and behaviors of our ancestors. They also study the fossils.
- The anthropologist explained the differences in the calvarium shape between different human populations as a reflection of geographical and environmental factors and adaptations throughout history. They also study the facial bone structures.
