概括
三胞胎腔 (Trigeminal Cavum) 是一个三胞胎腔.
科学领域:
- 神经外科 神经外科
- 放射学 放射学是一门学科.
背景情况:
- 三腔 (梅克尔洞) 的扩张通常与异常性内高血压有关.
- 三胞胎腔的正常解剖维度还没有很好地定义.
研究的目的:
- 为了解剖学地描述三角骨腔内的正常尺寸和状骨延伸.
- 重新评估三腔作为异常性内高血压的放射性标记物的实用性.
主要方法:
- 剖析了18个三角形腔体标本.
- 测量蜘蛛网的长度和宽度,以及它沿三角神经分支 (V1,V2,V3) 的延伸.
主要成果:
- 状囊附着在V1和V2上,没有骨底部延伸.
- 甲状腺延伸到V3测量2.5mm在中间,4.5mm在侧面,和4.0mm在后面.
- 三胞胎腔的蜘蛛体尺寸:20毫米宽,24.5毫米长.
结论:
- 在三腔内可变的形状延伸可能解释成像大小的变化.
- 蜘蛛网远远超出了以前的描述,特别是在V3附近.
- 这些发现质疑三腔大小在异常性内高血压的诊断价值.

01:21External Anatomy of the Kidney
1.2K
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

01:17Gross Anatomy of Bone
5.4K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
