There are currently no descriptions of neonatal tongue anatomy. Therefore, there have been no reports on the morphological differences between it and the adult tongue that would suggest its suitability for suckling. Serial coronal sections of a neonatal tongue were used to create a 3-dimensional model that was compared to that of the adult tongue. Compared to the adult human tongue, the neonatal tongue was found to contain 1) considerably less fat and soft tissue; 2) a thinner mucosa; 3) relatively enlarged extrinsic musculature; 4) a less-developed superior longitudinal muscle, resulting in a flat dorsal surface; and 5) attachments between the extrinsic muscles and the transverse muscle group that have not been identified in the adult tongue. The particular structure of the neonatal tongue suggests how the neonatal tongue is specialized for suckling.
目前尚无关于新生儿舌部解剖结构的描述。因此，也没有关于其与成人舌头形态差异的报道，而这些差异可能表明其适合哺乳。利用新生儿舌部的连续冠状切片创建了一个三维模型，并将其与成人舌头的三维模型进行比较。与成人舌头相比，发现新生儿舌头具有以下特点：1）脂肪和软组织明显较少；2）黏膜较薄；3）外在肌肉组织相对发达；4）上纵肌发育较差，导致舌背表面平坦；5）外在肌肉与横肌组之间存在成人舌头中未发现的附着结构。新生儿舌头的特殊结构表明了新生儿舌头是如何专门用于哺乳的。
