Anomalies of the brachial plexus have previously been described in the literature. The coracobrachialis muscle is typically innervated by the musculocutaneous nerve. During a gross anatomy dissection we found that the coracobrachialis muscle was innervated by a branch from the lateral root of the median nerve. Knowledge of the anatomical variations of the peripheral nervous system is important in interpreting unusual clinical presentations. This report will assist clinicians and surgeons by pointing out anatomical anomalies associated with the musculocutaneous nerve, the median nerve and their branches to the anterior compartment muscles of the upper arm.
臂丛神经异常此前已有文献报道。肱二头肌通常由肌皮神经支配。在一次大体解剖 dissection 中，我们发现肱二头肌由正中神经外侧根的一个分支支配。了解周围神经系统的解剖变异对于解释不寻常的临床表现很重要。本报告将指出与肌皮神经、正中神经及其至上臂前侧肌群分支相关的解剖异常，以帮助临床医生和外科医生。
