颈静脉孔(Jugular Foramen,JF)位于斜坡中线的两侧,内听道的下方,枕骨大孔的外上方,是后颅窝内重要的颅底通道。其位置深在,形状和大小变异较大,内有重要的神经血管穿行,包括颈内静脉、岩下窦、枕动脉脑膜支、咽升动脉脑膜支、舌咽神经、迷走神经、副神经等,毗邻重要复杂,故被 The jugular foramen (JF) is located on both sides of the midline of the slope, below the inner auditory canal, and above the foramen magnum, which is an important skull base channel in the posterior fossa.
