咽部的感觉和运动神经支配来自咽丛,咽丛由舌咽神经(CNIX)和迷走神经(CNX)的分支共同组成。一般认为,舌咽神经的主要分支司理咽部感觉(以咽鼓管至喉),另有单独分支布于舌后1/3和腭部支配感觉,舌咽神经唯一的运动神经支配茎突咽肌。多数学者认为,咽部缩肌和腭部肌肉(腭帆张肌除外)的运动神经支配来自迷走神经。然而也有解剖学者认为,舌咽神经
The pharyngeal sensation and motor innervation comes from the pharyngeal plexus, which is composed of the branches of the glossopharyngeal nerve (CNIX) and the vagus nerve (CNX). Is generally believed that the main branch of the glossopharyngeal nerve throat sensation (to the eustachian tube to the throat), and another branch located in the tongue 1/3 and the palate dominates the sensory, the sole motor nerve glossopharyngeal nerve styloid process Pharyngeal muscle. Most scholars believe that the motor innervation of the pharyngeal constrictor and palatal muscles (except for the palatal patella) originates from the vagus nerve. However, there are also anatomists think that glossopharyngeal nerve
