The location and number of taste buds were mapped in palatal epithelia of one-day old chicks and bud widths measured. Bud counts additionally were recorded for the tongue, and floor of the lower beak. An average of 316 taste buds was observed in the oral cavity of which 69%, 29% and 2% were distributed across oral epithelium in the upper beak (palate), lower beak and posteroventrolateral region of the anterior tongue, respectively. In each oral region, salivary gland ducts lying adjacent as well as gland ductules penetrating through the buds were prevalent. This relation may provide the bio-fluid milieu for receptor stimulation during feeding. Widths of palatal buds were bimodally distributed, peaking at diameters between 40-49 and 60-69 microns. The taste bud-rich oral epithelium in these one-day old chicks is consonant with their precocial nature. The topographic distribution of taste buds appears to be in register with those regions of epithelium contacted by food which is transported anteroposteriorly through the oral cavity by the chicken's prehensile tongue.
对1日龄雏鸡腭上皮中的味蕾位置和数量进行了定位，并测量了味蕾宽度。此外，还记录了舌头和下喙底部的味蕾数量。在口腔中平均观察到316个味蕾，其中69%、29%和2%分别分布在上喙（腭）、下喙和舌尖后腹外侧区域的口腔上皮中。在每个口腔区域，相邻的唾液腺导管以及穿透味蕾的腺小管都很常见。这种关系可能为进食期间的受体刺激提供生物流体环境。腭部味蕾的宽度呈双峰分布，在直径40 - 49微米和60 - 69微米之间达到峰值。这些1日龄雏鸡中富含味蕾的口腔上皮与其早成性相符。味蕾的地形分布似乎与通过鸡的抓握性舌头在口腔中前后运输的食物所接触的上皮区域一致。
