概括
股神经对于肩膀运动至关重要,显示出显著的解剖学变异性. 这项研究确定了四种分支模式,其中组合类型是最常见的,表明需要更新的分类系统.
科学领域:
- 人体解剖学 解剖学 解剖学
- 神经科学是一个神经科学.
- 手术解剖学手术解剖学
背景情况:
- 股神经是手臂的一个关键分支,激活了肩带.
- 它控制着像绑架和外部旋转这样的基本运动,这对于日常和运动活动至关重要.
- 关于股神经分支模式的现有文档有限.
研究的目的:
- 为了研究和分类股神经的分支配置.
- 为了分析南非尸体群体中股神经形态.
主要方法:
- 剖析30个成年尸体 (15个男性,15个女性).
- 识别表面解剖学标志 (形体,心脏体过程) 以精确地定位神经.
- 标准的剖析协议涉及肌肉反射暴露神经和周围的神经血管结构.
主要成果:
- 鉴定和分类了四种不同的股神经分支模式.

3.1K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:12Arteries of the Upper Limbs
2.7K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
