Cranial Bones: Superior and Posterior View01:14

Cranial 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,...

PPE Use in Healthcare Settings I: Donning

946
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Sutures of the Skull01:22

Sutures 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...

Bending of Members Made of Several Materials

147
In analyzing a structural member composed of two different materials with identical cross-sectional areas, it is crucial to understand how their distinct elastic properties affect the member's response under load. The analysis involves assessing stress and strain distributions using the transformed section concept, which accounts for variations in material properties.
Hooke's Law determines stress in each material, stating that stress is proportional to strain but varies due to each...

科学领域:

  • 运动医学 运动医学
  • 生物力学 生物力学
  • 武术安全 武术安全

背景情况:

  • 肯多头盔是基于传统的武士盔甲,缺乏现代的第三方安全测试.
  • 现有的肯多头盔设计还没有发展到有效地解决头部创伤减轻问题.

研究的目的:

  • 为了评估不同的肯多头盔接模式和填充材料如何影响冲击力吸收.
  • 评估性别和肯多等级 (Dan/Kyu) 对这些安全指标的影响.
  • 确定最佳的头盔设计,以防止运动相关的脑震荡 (SRC) 在肯多.

主要方法:

  • 利用装有传感器的模型分析了超过4000次模拟的肯多打击.
  • 测试了各种头盔接宽度 (2-9毫米) 和填充类型 (聚氨,棉).
  • 收集了10名肯多练习者 (6名男性,4名女性) 的数据,以评估影响差异.

主要成果:

  • 带有更宽接线 (8-9毫米) 的头盔显著更好地吸收能量,减少了平均g力 (p < 0.001).
  • 与棉相比,聚氨填充提供了统计学上显著的冲击力降低 (p < 0.001).
  • 男性和更高级别的 (Dan) 实践者产生了显著更强大的影响 (p < 0.001).

结论:

  • 肯多头盔的接宽度和填充材料极大地影响了脑震荡保护.
  • 较宽的纹图案和聚氨填充物提供了卓越的安全优势.
  • 需要进一步的研究,以了解性别和等级之间的突出力量差异如何影响肯多比赛结果.
