Abstract:
Anatomical variations are essential in the fields of surgery and anesthesia. It also assists in the evaluation of
patient symptoms in cases of neuropathies and trauma. During the regional dissection of formalin-fixed male
cadavers at the Department of Human Anatomy at National University Faculty of Medicine for undergraduate
students of second and third classes, academic years 2016-2017, accessory phrenic nerve (APN) was observed
join the phrenic nerve near the neck root. The knowledge of these anatomical variations helps the physicians in
symptoms interpretation.
