关于小口腔腺的研究中,对排泄管的形态学研究非常少,特别是对口唇腺导管走行的研究,我们尚未见到。作者以前曾观察了各种导管的走行情况,此次仅就口唇腺报导一些见解。 1.口唇腺的外形:口唇腺在唇粘膜内呈带状扩布,上口唇腺以正中线分为左侧和右侧两个腺叶群,下口唇腺形成左右相连续的腺叶群。这种情况与颜面的发生过程有关。上颌突的愈合在胚胎第6～7周,下颌突的愈合在第四周,口唇腺的发生在第7周以后,由于上唇的愈合比下唇晚,因为造成上口唇腺叶的不连续性。 2.口唇腺导管的走行:制作上唇的点状连续组织切片,观察口唇腺及其导管,多数腺叶并非无次序的散在,而是按一定的方式排列的,各个导管也是有规律的从上内方斜向下
In the study of small oral glands, there are very few morphological studies on drainage tubes, especially the study of the ducts of the labial glands, which we have not yet seen. The author previously observed the various catheters and reported only some opinions on the labial glands. 1. The shape of the labrum glands: The labial glands are banded in the mucosa of the lips. The upper labial glands are divided into two gland groups on the left and right sides with the median line, and the lower labial glands form the left and right contiguous glands. This situation is related to the process of appearance. The maxillary protrusion heals at the 6th to 7th week of the embryo, and the mandibular protrusion heals at the fourth week. The labial gland occurs after the 7th week. The upper lip is healed later than the lower lip because of the discontinuity of the upper labial gland. . 2. Walk of the labial gland duct: Make a point-like continuous tissue section of the upper lip and observe the labial glands and their ducts. Most of the glands and leaves are not randomly scattered, but are arranged in a certain manner. Each of the catheters is also regular from above. Inside is slanting down
