目的：为了更清楚地描述软腭的组织组成和结构，特别是对骨柱之间的中央部分进行了重点描述，标本：9例女性和3例男性正常成人软腭标本。前四分之一包含大量的粘液分泌腺组织，以及丰富的脂肪组织。腭帆张肌腱在硬腭后部的最前部区域突出，靠近鼻面。软腭中部三分之一的肌肉组织主要包括：（1）腭帆提肌纤维横向穿过中线，没有间隔中断;（2）悬雍垂肌纤维包裹在鞘中，纵向走行，垂直于提肌悬带并由其支撑;（3）腭咽肌纤维位于侧面，不接近中线。悬雍垂肌是可变的，在其配对与不配对nature.Conclusions：软腭从硬腭的后缘腭帆提肌吊索的解剖标本之间是一致的，这表明在这个地区的结构有一个统一的功能，在所有科目。悬雍垂肌的配对与不配对的性质在标本内和标本间都是可变的。软腭的后三分之一在不同组织类型的相对数量和分布方面在标本之间是可变的。
Objective: To describe more clearly the tissue composition and structure of the human soft palate with particular emphasis on the central portion between the faucial pillars.Specimens: Nine female and three male normal adult human soft palate cadaver specimens.Results: The anterior soft palate consists of fairly uniform layers. The anterior one fourth contains a substantial investment of mucous-secreting glandular tissue, as well as an abundance of adipose tissue. The tensor veli palatini tendon is prominent in the most anterior region just posterior to the hard palate and close to the nasal surface. The middle one third of the soft palate is largely invested with muscle tissue consisting of (1) levator veli palatini fibers coursing transversely across the midline without a septal interruption, (2) musculus uvulae fibers encapsulated in a sheath and coursing longitudinally, perpendicular to and cradled by the levator sling, and (3) palatopharyngeus fibers located laterally and not approaching the midline. Musculus uvulae is variable across and within specimens in terms of its paired versus unpaired nature.Conclusions: The anatomy of the soft palate from the posterior border of the hard palate to the levator veli palatini sling is consistent among specimens, suggesting that structures in this region have a uniform function across subjects. The paired versus unpaired nature of musculus uvulae is variable both within and between specimens. The posterior one third of the soft palate is variable across specimens with regard to the relative amount and distribution of different tissue types.
