We microscopically examined the dorsal lingual surface of an adult chimpanzee (Pan troglodytes). The tongue of the chimpanzee was about 13 cm long. Filiform papillae were distributed over the entire dorsal surface of the lingual body. There were many fungiform papillae scattered among the filiform papillae. At the posterior end of the lingual body, a triangular arrangement of the vallate papillae, with the apex of the triangle directed posteriorly, was observed. The filiform papillae on the lingual apex consisted of a main papilla and secondary papillae. The filiform papillae on the lingual body had several pointed processes. There were dome-shaped fungiform papillae scattered among the filiform papillae. The vallate papillae were surrounded by grooves and were flattened-oval shaped. Many foliate papillae were observed on the posterolateral regions of the tongue.
我们对一只成年黑猩猩（黑猩猩属）的舌背表面进行了显微镜检查。黑猩猩的舌头约13厘米长。丝状乳头分布在舌体的整个背表面。在丝状乳头之间散布着许多菌状乳头。在舌体后端，观察到轮廓乳头呈三角形排列，三角形的顶端指向后方。舌尖上的丝状乳头由一个主乳头和副乳头组成。舌体上的丝状乳头有几个尖突。在丝状乳头之间散布着圆顶形的菌状乳头。轮廓乳头被凹槽包围，呈扁平椭圆形。在舌头的后外侧区域观察到许多叶状乳头。
