A particular nerve bundle which may be called phrenicosuprascapular communication is, although only rarely, met with in various forms in man. By teasing, fibres of this communication are revealed to belong to the most anterior components of the brachial plexus, being closely associated with anterior nerves such as the phrenic, accessory phrenic, subclavius and even pectoralis. It is, therefore, obvious that the nervus suprascapularis conveys anterior fibres. It may be interpreted that the anteriormost nerve fibres may be separated from the main cord(s) and form an irregular network or plexus for themselves. It should be stressed that the n. suprascapularis consists of all the anterior components of the brachial plexus and that this is an anterior nerve.
一种可称为膈神经-肩胛上神经交通支的特殊神经束，尽管在人类中极为罕见，但有多种形式。通过解剖发现，该交通支的纤维属于臂丛最前部的成分，与膈神经、副膈神经、锁骨下肌甚至胸肌等前部神经密切相关。因此，肩胛上神经显然传导前部纤维。可以这样解释，最前部的神经纤维可能从主束中分离出来，自身形成一个不规则的网络或神经丛。应当强调的是，肩胛上神经由臂丛的所有前部成分组成，它是一条前部神经。
