淚腺:

交感神經:抑制淚腺分泌
T1 > 上頸交感神經節(sup. cervical sympathetic gangilion,SSG) > sympathetic plexus around 內頸動脈(internal carotid a.,ICA) > 深岩神經(deep petrosal n.) > 翼腭神經節(pterygopalatine ganglion,PPG) > 顴神經(zygomatic n.) > 淚腺(lacrimal gland)
副交感神經:刺激淚腺分泌
上延核(sup. salivary nucleus) > CN7 > 膝狀神經節(geniculate ganglion) > 大岩神經(greater petrosal n.) > 翼腭神經節(pterygopalatine ganglion,PPG) > 顴神經(zygomatic n.) > 淚腺(lacrimal gland)
感覺神經:
CN5-1 > 三叉神經節(trigeminal ganglion,TG) > 淚腺(lacrimal gland)
