Previous investigations have ascertained, according to the results obtained by Bradley et al. (1980) in the sheep, that the laryngeal surface of the epiglottis of goat and bovine is always provided with numerous taste buds. These observations have verified in other ruminant species, as the moufflon and the buffalo, the validity of the above-named datum and have ascertained that it is always inconstant in the other animal species considered (wild boar, coypu). These taste buds show a typical structure (diameter of the outer taste pore varying from 2.7 to 4.2 micron, width of the chemoreceptors varying from 30 to 60 micron and length from 27.5 to 57.5 micron). Moreover, the normal structure of the above-named taste buds is also testified by the arrangement of their innervation and particularly by the integrity of the synaptic contacts. The results of the present research have permitted a critical and more severe examination of the probable functional role of those laryngeal receptors. In fact, in the ruminants they may protect the deep airways precluding to food particles the larynx in the phase of food regurgitation.
先前的研究已根据布拉德利等人（1980年）在绵羊身上获得的结果确定，山羊和牛会厌的喉面总是有许多味蕾。这些观察结果已在其他反刍动物物种（如摩弗伦羊和水牛）中得到验证，证实了上述数据的有效性，并确定在所研究的其他动物物种（野猪、河狸鼠）中该情况并非始终不变。这些味蕾呈现出典型的结构（外部味孔直径在2.7至4.2微米之间，化学感受器宽度在30至60微米之间，长度在27.5至57.5微米之间）。此外，上述味蕾的正常结构也通过其神经支配的排列，特别是突触接触的完整性得到证实。本研究结果使得对那些喉部感受器可能的功能作用进行了更为严格和批判性的审视。事实上，在反刍动物中，它们可能通过在食物反流阶段阻止食物颗粒进入喉部来保护深部气道。
