Cranis

Cranis refers to the skull or the cranial part of the vertebral column. It is a complex structure composed of numerous bones, cartilages, and other tissues that protect the brain and facilitate various functions such as sensory perception, thermoregulation, and the production of cerebrospinal fluid. The human cranis, for instance, is comprised of 22 bones that fuse together during the process of craniosynostosis.

Cranis can be divided into different regions, including the cranium proper, which constitutes the upper part of the skull, and the face, which forms the anterior region. The cranium proper houses the brain, sensory organs, and the pituitary gland, a crucial endocrine gland. The face, on the other hand, houses the nasal cavities, the oral cavity, and the eyes, among other components.

In various cultures, the term cranis can be associated with non-anatomical interpretations. In some mythologies, the cranis is seen as the dwelling place of the soul or a perfect sphere associated with the sky. Artifacts such as the Egyptian Cartonnage, portraying a realistic view of the cranis, are often found in ancient Egyptian tombs.

From an anatomical perspective, the cranis plays a crucial role in PSV (Pressure Support Ventilation) and other treatment methods for conditions including osteogenesis imperfecta and mucopolysaccharidosis type II. Cephalometric views, orthodontic treatment, and craniosynostosis reconstruction are also fields where the understanding of cranis is essential.

Studies focus on aspects like brain injury patterns, or brain spericity changes in response to intracranial pressure, in order to understand the cranis's functions in relation to its structural changes. Research in the subdomains of agenesis of corpus callosum, pituitary origins, and arachnoid cysts underscores the importance of cranis in relation to a living being's brain and nervous system.
