概括
在800名克罗地亚人中研究了metopism的发生率,这是一个持久的metopic suture. 结果显示,随着时间的推移或性别之间的metopism频率没有显著变化.
科学领域:
- 人类学是人类学.
- 人体解剖学 解剖学 解剖学
- 古病理学 古病理学
背景情况:
- 梅托皮是胎儿头骨中的正常解剖特征,在生命的第二年通常会融化.
- 隐形 (metopic suture) 的持续性 (metopism) 是一种常见的头骨异常,在不同的人群和时间段的患病率有所不同.
研究的目的:
- 调查metopism在现代和考古克罗地亚人群中的发生率.
- 确定克罗地亚人口中是否存在随着时间的推移而形成的世俗化趋势.
主要方法:
- 总共分析了800个标本,包括454个现代多切片计算机断层扫描 (MSCT) 扫描和346个干燥的考古头骨.
- 进行视觉检查以确定是否存在一个完整的metopic,定义为一个对齐的 nasion 到 bregma.
- 统计分析,包括千二测试,用于比较现代和考古样本之间的metopism频率,以及性别.
主要成果:
- 在总样本中的4.5% (36个800个) 观察到metopism,男性 (4.5%) 和女性 (4.6%) 的频率相似.
- 在现代和考古样本 (P=0.359) 或性别 (P=0.939) 之间,没有发现metopism发生率的显著差异.
- 梅托普主义的频率从现代人口的3.5%到罗马时期的样本中的7.04%.
结论:
- 这项研究没有发现克罗地亚人口在不同历史时期的metopic持久性的世俗变化的证据.
- 观测到的转移频率变化可能归因于不同时期的样本大小差异.
- 这些发现表明,在克罗地亚人口中,随着时间的推移,metopism的流行率稳定.

01:22Sutures of the Skull
6.6K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:27Cranial Bones: Lateral View
2.2K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

3.2K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

01:14Cranial Bones: Superior and Posterior View
2.1K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
