颅骨(skull)和头盖骨(cranium)的区别

颅骨和头盖骨是保护大脑和支撑头部其他软组织的两个重要骨骼部分，但根据它们的结构可以看出它们之间的区别。头骨和头盖骨的主要区别在于头骨是一个复杂的结构，包含22块骨头，而头骨是头骨的一个分支，只有8块骨头。在这篇文章中，颅骨和头盖骨之间的进一步区别将被强调。

什么是颅骨(skull)？

The human skull is a complex structure c***isting of 22 bones which mainly comprises cranial bones (8) and facial bones (14). The skull is located on the atlas of the vertebral column. The main cavity of the skull that encloses the brain is called cranium cavity. The other several cavities found within the skull are called sinuses that accommodate the hearing and equilibrium structures. The great architectural design of the skull reflects its many functi***. Most importantly, it provides protection for the most important organ of the nervous system; the brain. Moreover, the skull is involved in speech, breathing, vision, and hearing. Facial bones provide surfaces to muscle attachments and make passages to respiratory and digestive systems.

什么是头盖骨(cranium)？

The cranium is a subdivision of the skull that c***ists of 8 bones, which enclose the brain. The eight bones include ethmoid, frontal, occipital, parietal (2), sphenoid, and temporal (2). Among these bones, parietal bones and the frontal bone are the largest. The main role of the cranium is to protect the brain. In addition, cranium provides a surface for the attachment of muscles that helps the movement of the head and supports the sense organs located in the head. The walls of cranial walls are composed of two plates. The edge of each bone is joined with an adjacent bone edge through fibrous interlocking joints called ‘sutures’. The sutures are unique to cranial bones.
