面神经系第七对脑神经为复杂的脑神经,属混合性脑神经,在脑神经疾病中,面神经麻痹是很常见的,因此,了解面神经的解剖,对临床工作来说,具有重要意义。 一、纤维成份 面神经的纤维成份如下。1.运动纤维:动物纤维自脑桥面神经核发出,分布于面部表情肌,镫骨肌,茎突舌骨肌、二腹肌后腹、颈阔肌,司随意运动。2.味觉纤维:起于舌前2/3味蕾,经鼓索神经,中间神经(含味觉分泌纤维)传至延髓孤束核,纤维上行达丘脑,经内囊至中央后回下方,司舌前2/3味觉。3.分泌纤维:发自
Facial nerve The seventh pair of cranial nerves is a complex cranial nerve, which is a mixed cranial nerve. Facial nerve paralysis is very common in cranial nerve diseases. Therefore, understanding facial nerve anatomy is of great significance to clinical work. First, the fiber component Facial nerve fibers are as follows. 1 sports fiber: animal fibers issued from the pons of the pontine nerve, distributed in the facial expression muscles, tarsal muscles, stylohyoid muscles, biceps posterior abdomen, platysma, Secretary free exercise. 2. Taste fibers: from the tongue before the 2/3 taste buds, the chordoma nerve, the median nerve (including the secretion of taste fibers) to the medulla oblongata nucleus, fiber up the thalamus, after the internal capsule to the center back below the tongue Top 2/3 taste. 3. Secretion of fiber: from
