Major nerves and vessels run alongside each other in a "neurovascular bundle" kept together by connective tissue that is often referred to by anatomists, surgeons, and anesthesiologists as the "sheath." Our goal was to macroscopically demonstrate the brachial plexus sheath in embalmed and fresh cadaver dissections.
Systematic dissections were performed on 11 embalmed cadavers (6 females and 5 males), plus one fresh, unembalmed male cadaver. Dissections were started in the arm, and progressed proximally to the axilla and the supraclavicular area. Notes and photographic documentation were obtained.
A sheath around the neurovascular bundle of the brachial plexus was visible to the naked eye in every dissection. The sheath had a fibrous external appearance, and was filled with loose connective tissue. No evidence of septa was found.
We observed a macroscopic fibrous structure surrounding the plexus, which was filled with loose connective tissue lacking any apparent organization.
主要神经和血管在由结缔组织维系在一起的“神经血管束”中彼此并行，解剖学家、外科医生和麻醉医生常将该结缔组织称为“鞘”。我们的目标是在防腐处理的尸体和新鲜尸体解剖中宏观展示臂丛神经鞘。
对11具防腐处理的尸体（6具女性和5具男性）以及1具未经防腐处理的新鲜男性尸体进行系统解剖。解剖从手臂开始，向近端延伸至腋窝和锁骨上区域。记录并拍照存档。
在每次解剖中，肉眼均可观察到臂丛神经血管束周围的鞘。该鞘外观呈纤维状，内部充满疏松结缔组织。未发现有隔膜的迹象。
我们观察到神经丛周围有一个宏观的纤维结构，内部充满缺乏明显组织结构的疏松结缔组织。
