喻氏有言曰∶不明十二经络，动手便错，况咽喉为关要之枢，故尤须明晰为要。兹于《类经》所集，咽喉、
齿、唇、项、颈、口、舌诸经络附录于上，以备参考，庶临证不致茫然而无所措也。
舌：舌是心的外候器官，其色中央呈黄色，内通于脾，开窍于口，因此病变常反映在舌根。足少阴肾经贯穿肾脏并联系舌根。心主司舌，其外候为舌。在五行中属火、气运升明的年份，其主管部位为舌。足太阴脾经连接舌根，散布于舌下。足少阴肾经夹行于舌根两侧。足太阴脾经贯穿舌中。足少阴肾经直行者系连舌根，足少阴肾经亦贯通舌下。足少阴肾经的标部位于（此处原文缺字，通常指背部俞穴）及舌下的两条脉络。足少阴肾经上行系连于舌。手少阴心经的别络系连舌根。手少阳三焦经的筋脉分支进入并系连舌根。足太阴脾经的筋脉分支另入并结聚于舌根。上焦之气上行至舌。厥阴经即肝经，肝主筋，筋汇聚于前阴而脉络联系于舌根。胃中的浊气上行至唇舌从而产生味觉。心气通达于舌，心气调和则舌能辨别五味。
齿牙：手阳明大肠经进入下齿中。足阳明胃经向下沿鼻外侧进入上齿中。手阳明大肠经的别络遍布牙齿。手少阳三焦经的筋脉分支上行至颊车穴附近。足阳明胃经循行经过牙车（下颌骨）。足太阳膀胱经有支脉进入牙齿，名为角孙穴，治疗上齿龋痛可取此穴。牙齿是骨骼的余气所生。
口：中央黄色，内通于脾，开窍于口。脾主司口，其外候为口。在五行中属土、气运备化的年份，其主管部位为口。手阳明大肠经挟持口部。足阳明胃经向上挟持口部。足阳明胃经出于口部。脾气通达于口，脾气调和则口能辨别五谷的味道。冲脉联络唇口。
唇：脾与肌肉相合，其荣华表现于唇。脾、胃、大肠、小肠、三焦、膀胱，是仓廪之本，其荣华表现于口唇四周的白色区域。督脉环绕嘴唇。足阳明胃经环绕嘴唇。足厥阴肝经环绕唇内。口唇是脾的外候器官。唇和舌，是肌肉的根本所在。
项颈：督脉的别络上行至项部。督脉还出别行下行至项部。足太阳膀胱经下行至项部。足太阳膀胱经循行于项部。手太阳小肠经循行于项部。手少阳三焦经上行至项部。足厥阴肝经循喉咙之后，上行进入颃颡（鼻咽部）。足太阳膀胱经从脊背肌肉上行出于项部。足少阴肾经系连舌根，复出至项部。足阳明胃经的别络上行至头项。足少阴肾经的筋脉夹脊背上行至头顶。手太阳小肠经的筋脉，分支者循颈部，出于足太阳经之前。手阳明大肠经的筋脉直行者，从肩部上行至颈部。中央的经脉是督脉。冲脉上行者出于颃颡。肌肉的精气形成约束眼目的眼睑（此处原文“约束”多指眼睑，但语境在项颈，可能指颈部筋膜或泛指筋肉约束），包裹筋骨血气的精气，与脉系向后出于项中。
喻昌（喻氏）曾说：“如果不明白十二经络，动手施治就会出错，何况咽喉是人体关要之枢，所以尤其需要明晰。”兹将《类经》中收集的关于咽喉、齿、唇、项、颈、口、舌等部位的经络附录于上，以备参考，希望临证时不至于茫然无措。
Tongue: The tongue is the external manifestation of the Heart (Xin). Its central color is yellow, internally connecting to the Spleen (Pi), and opening into the mouth; therefore, pathological changes often manifest at the root of the tongue. The Foot-Shaoyin Kidney Meridian (Zu Shao Yin Shen Jing) passes through the kidney and connects to the root of the tongue. The Heart governs the tongue, with its external orifice being the tongue. In years characterized by the ascending fire phase (Sheng Ming Zhi Ji), the tongue is the primary organ. The Foot-Taiyin Spleen Meridian (Zu Tai Yin Pi Jing) connects to the root of the tongue and spreads beneath it. The Foot-Shaoyin Kidney Meridian flanks the root of the tongue. The Foot-Taiyin Spleen Meridian penetrates the middle of the tongue. The straight branch of the Foot-Shaoyin Kidney Meridian ties to the root of the tongue, and the Foot-Shaoyin Kidney Meridian also penetrates below the tongue. The marked points (Biao) of the Foot-Shaoyin Kidney Meridian are located at [missing character in original text, typically referring to Back-Shu points] and the two vessels under the tongue. The Foot-Shaoyin Kidney Meridian ascends and ties to the tongue. The divergent vessel of the Hand-Shaoyin Heart Meridian (Shou Shao Yin Xin Jing) ties to the root of the tongue. The sinew branch of the Hand-Shaoyang Sanjiao Meridian (Shou Shao Yang San Jiao Jing) enters and ties to the root of the tongue. The sinew branch of the Foot-Taiyin Spleen Meridian separates and knots at the root of the tongue. The Upper Jiao (Shang Jiao) qi ascends to the tongue. The Jueyin Meridian is the Liver Meridian (Gan Mai); the Liver governs sinews, which gather at the genitalia and network to the root of the tongue. Turbid qi from the stomach travels to the lips and tongue to produce taste. Heart Qi communicates with the tongue; when Heart Qi is harmonious, the tongue can discern the five flavors.
Teeth and Gums: The Hand-Yangming Large Intestine Meridian (Shou Yangming Da Chang Jing) enters the lower teeth. The Foot-Yangming Stomach Meridian (Zu Yangming Wei Jing) descends along the lateral side of the nose and enters the upper teeth. The divergent vessel of the Hand-Yangming Large Intestine Meridian covers all teeth. The sinew branch of the Hand-Shaoyang Sanjiao Meridian ascends to the vicinity of the Jiache acupoint (Jiache, ST6). The Foot-Yangming Stomach Meridian follows the mandible (Yache). The Foot-Taiyang Bladder Meridian (Zu Tai Yang Pang Guang Jing) has a branch entering the teeth, named Jiaosun; for caries of the upper teeth, this point should be selected. Teeth are the surplus of bone essence.
Mouth: The central color is yellow, internally connecting to the Spleen, and opening into the mouth. The Spleen governs the mouth, with its external orifice being the mouth. In years characterized by the earth phase (Bei Hua Zhi Ji), the mouth is the primary organ. The Hand-Yangming Large Intestine Meridian flanks the mouth. The Foot-Yangming Stomach Meridian ascends and flanks the mouth. The Foot-Yangming Stomach Meridian emerges from the mouth. Spleen Qi communicates with the mouth; when Spleen Qi is harmonious, the mouth can discern the flavors of the five grains. The Chong Mai (Penetrating Vessel) networks the lips and mouth.
Lips: The Spleen combines with muscles, and its luster manifests in the lips. The Spleen, Stomach, Large Intestine, Small Intestine, Sanjiao, and Bladder are the foundation of the granary; their luster manifests in the four white areas around the lips. The Du Mai (Conception Vessel of the back) circles the lips. The Foot-Yangming Stomach Meridian circles the lips. The Foot-Jueyin Liver Meridian (Zu Jue Yin Gan Jing) circles inside the lips. The lips are the external manifestation of the Spleen. The lips and tongue are the root of the muscles.
Neck and Nape: The divergent vessel of the Du Mai ascends to the nape. The Du Mai returns and branches down to the nape. The Foot-Taiyang Bladder Meridian descends to the nape. The Foot-Taiyang Bladder Meridian follows the nape. The Hand-Taiyang Small Intestine Meridian (Shou Tai Yang Xiao Chang Jing) follows the nape. The Hand-Shaoyang Sanjiao Meridian ascends to the nape. The Foot-Jueyin Liver Meridian follows behind the throat and ascends into the Hangsang (nasopharynx). The Foot-Taiyang Bladder Meridian ascends from the back muscles and emerges at the nape. The Foot-Shaoyin Kidney Meridian ties to the root of the tongue and re-emerges at the nape. The divergent vessel of the Foot-Yangming Stomach Meridian ascends to the head and nape. The sinew of the Foot-Shaoyin Kidney Meridian flanks the spine and ascends to the vertex. The sinew branch of the Hand-Taiyang Small Intestine Meridian follows the neck, emerging anterior to the Foot-Taiyang Meridian. The straight branch of the sinew of the Hand-Yangming Large Intestine Meridian ascends from the shoulder to the neck. The central meridian is the Du Mai. The ascending branch of the Chong Mai emerges from the Hangsang. The essence of muscles forms the constraints (eyelids/ligaments), wrapping the essence of sinews, bones, blood, and qi, connecting posteriorly to emerge at the nape.
Yu Chang (Yu Shi) stated: "If one does not understand the Twelve Meridians, any manual intervention will be erroneous. How much more so for the throat and pharynx, which are the pivotal gates of the body; thus, clarity regarding them is essential." Herein, the meridians related to the throat, pharynx, teeth, lips, nape, neck, mouth, and tongue, as collected in *Lei Jing* (Classified Classic), are appended above for reference, so that during clinical practice, one may avoid confusion and helplessness.
