1.在70例胎儿及婴儿尸体上用器官内淋巴管注射的方法,观察了鼻咽部的淋巴管及其局部淋巴结。 2.在鼻咽部粘膜层具有一层毛细淋巴管网,于咽鼓管扁桃体及咽扁桃体处最为密集。粘膜层毛细淋巴管注入粘膜下淋巴管,后者汇成数条输出管。 3.从鼻咽部后壁走出的输出管注入咽后内、外侧淋巴结,或是经过颈内动、静脉的后方,注入乳突尖部深处的颈上深淋巴结。 4.从鼻咽部侧壁走出的输出管,注入颈内动、静脉出入颅底处前方的淋巴结,或向下入颈静脉二腹肌淋巴结及在舌动脉起点至颈总动脉分岐处之间的颈上深淋巴结。 5.咽后外侧淋巴结位于寰椎侧块高度,有1～2个;咽后内侧淋巴结紧贴咽腱膜,仅有1个。充色的颈静脉二腹肌淋巴结仅有一个,形体较大。
1. In 70 cases of fetal and infant carcasses with organ lymphatic injection method, observed the nasopharyngeal lymph tube and its local lymph nodes. 2. In the nasopharyngeal mucosa with a layer of lymphatic network, in the eustachian tube tonsils and pharyngeal tonsils at the most intensive. Submucosal lymphatic capillary into the submucosal lymphatic vessels, which merge into several output tubes. 3. Out of the nasopharynx posterior wall of the output tube injected into the posterior pharyngeal, lateral lymph nodes, or after the end of the carotid artery and vein, into the deep papillae deep cervical lymph nodes. 4. From the nasopharynx wall out of the output tube into the carotid artery and vein access to the skull base at the front of the lymph nodes, or down into the jugular vein of the abdominal muscles lymph nodes and the beginning of the lingual artery to the common carotid artery between the divisions Deep cervical lymph nodes. Posterior pharyngeal lymph nodes in the atlas lateral mass height, there are 1 to 2; posterior pharyngeal lymph nodes close to the phalanges, only 1. There is only one colonic muscle in the jugular vein with larger body.
