首次对一例新生河马的双侧臂丛进行了解剖研究，发现常见河马的臂丛解剖尚未见报道。结果表明：(1)臂丛神经由第五颈(C5)至第一胸(T1)神经组成。它们形成了两条主干，C5-C6和C7-T1；此外，腋动脉在C6和C7之间穿行，(2)臂肌的独特分支和从正中神经分支出来的前臂外侧皮神经的独特分支，(3)神经纤维分析表明，来自正中神经的这些独特的神经分支与肌肉皮肤(MC)神经密切相关，在结构上类似于肌肉皮肤(MC)神经，但它们的行程从MC改变到正中神经，(4)这种独特的分支模式很可能是两栖类、爬行动物和某些哺乳动物臂丛的共同形态特征。
The anatomy of the brachial plexus in the common hippopotamus (Hippopotamus amphibius), which has not been previously reported, was first examined bilaterally in a newborn hippopotamus. Our observations clarified the following: (1) the brachial plexus comprises the fifth cervical (C5) to first thoracic (T1) nerves. These formed two trunks, C5–C6 and C7–T1; in addition, the axillary artery passed in between C6 and C7, (2) unique branches to the brachialis muscle and those of the lateral cutaneous antebrachii nerves ramified from the median nerve, (3) nerve fibre analysis revealed that these unique nerve branches from the median nerve were closely related and structurally similar to the musculocutaneous (MC) nerve; however, they had changed course from the MC to the median nerve, and (4) this unique branching pattern is likely to be a common morphological feature of the brachial plexus in amphibians, reptiles and certain mammals.
