概括
尾 (OS) 在中脑和小脑头骨中更常见,特别是在老年男性中. 脊髓是这个CBCT研究中观察到的最常见的头骨类型.
科学领域:
- 人体解剖学 解剖学 解剖学
- 放射学 放射学是一门学科.
- 人类学是人类学.
背景情况:
- 尾突起 (OS) 是外部尾突起 (EOP) 的异常延长.
- 头骨指数 (CI) 通过宽度与长度的关系来量化头骨形状.
研究的目的:
- 为了确定尾 (OS) 的频率和类型.
- 通过使用圆束计算断层扫描 (CBCT) 来分析头脑指数 (CI) 分布和头骨类型.
- 调查CI与OS存在/类型之间的关系.
主要方法:
- 分析了523名患者的CBCT扫描.
- OS被分为平面 (类型1),顶峰 (类型2) 和脊柱 (类型3) 的类型.
- 测量了头骨尺寸,以计算CI,并对头骨类型进行分类 (双头脑,中头脑,胸头脑,超胸头脑).
主要成果:
- 胸头骨是最常见的 (44.7%),其次是中脑 (28.3%),超胸头骨 (21.2%),以及胸头骨 (5.7%).
- 54.3%的参与者没有OS;OS类型是平面 (23.1%),顶峰 (15.3%),和脊椎 (7.2%).
- 在OS频率和头骨类型之间发现了显著的关联 (P <0.05).
结论:
- 胸头是主要的头骨类型. 在中脑和双脑头骨中,尾刺更为普遍.
- OS发生与年龄较大和男性个体有关.
- 这项CBCT研究为头骨指数和尾之间的关系提供了新的见解.

01:14Cranial Bones: Superior and Posterior View
2.2K
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,...

01:16Vertebral Column: Regions and Curvature
3.6K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
