上牙丛
Plexus dentalis superior
定义
上牙槽神经丛是位于上颌骨(即上颌骨)厚实的牙槽突内的神经丛,位于上方的上颌窦与下方的上颌牙齿之间。该神经丛由三条神经的分支汇合而成,分别是:上牙槽后神经(起自翼腭窝内的上颌神经)、上牙槽中神经和上牙槽前神经(均为眶下神经的分支)。这些神经在上颌窦黏膜外侧下行,并沿途支配上颌窦黏膜。随后,这些神经在上颌窦下方相互吻合,形成上牙槽神经丛。
上牙槽神经丛支配上颌牙根、上颌牙龈及颊黏膜。神经丛的后部接受上牙槽后神经的分支,支配上颌磨牙的牙根;中部接受上牙槽中神经的分支,支配前磨牙;前部来自上牙槽前神经,支配尖牙和切牙。上牙槽神经丛的前部还发出一支鼻支,该鼻支穿过鼻腔外侧壁上的一个小孔,最终为鼻腔下鼻道黏膜及鼻腔底的黏膜提供感觉神经支配。
