对３０例成人尸体的翼外肌及其血管神经的来源、分支及分布进行了观察与测量。翼外肌上、下头有明确的起止位置，其营养血管来源单一，口径细小，每侧翼外肌以４条动脉供血多见。翼外肌的神经支配分为３型，其中（Ⅰ型）翼外肌上头由颊神经支配，其下头由翼外肌神经支配较为常见。 The origins, branches and distributions of the pterygoid muscle and its vascular nerves in 30 adult cadavers were observed and measured. Wing outside the wing, the bottom has a clear start and stop position, its single source of nutrient vessels, small caliber, lateral muscle of each side to four arteries more common. The pterygoid nerve innervation is divided into 3 types, of which the type I pterygoid is dominated by the buccal nerve, and the lower part is dominated by the pterygoid nerve.
