The middle layer is the lamina propria and it contains blood and lymph vessels.

粘膜的中为固有，内含血管和淋巴管。

One type of daughter cell — known as a type A cell — stays up near the basal lamina and just keeps dividing, so you never run out of spermatogonia.

有一种子细胞——也就是众所周知的 A 型细胞——会待在基底附近并不断分裂，所以精原细胞永远不会耗尽。

Alvarez wondered what it was about a thin lamina of clay, barely a quarter of an inch thick, that could account for such a dramatic moment in Earth's history.

阿尔瓦雷斯不大明白，只有6毫米左右厚的薄薄一黏土，怎么能说明地球史上这么个戏剧性的时。

Going deeper past that layer you've got the basement membrane and loose connective tissue, called the lamina propria—which together with the epithelium makes up the mucosa.

基底膜细胞和疏松结缔组织组成，被称为基底，它和上皮一起组成了气道的黏膜。

Lastly the gastric mucosa is highly vascularized, which helps deliver oxygen and bicarbonate and carry away acid that makes it through into the lamina propria.

最后，胃粘膜高度血管化，这有助于输送氧气和碳酸氢盐并带走酸，使其通过固有。

In the bronchioles you've got the lumen, the mucosa which includes the inner lining of epithelial cells as well as the lamina propria, and the submucosa which is where the smooth muscle lives.

在细支气管内，有腔体、粘膜（包括上皮细胞的内、固有），以及粘膜下，也就是平滑肌所在的地方。

Inside the stomach, the epithelial layer is made up of cylindrical cells, which dive into the lamina propria, forming pits.

在胃内，上皮柱状细胞组成，这些细胞入固有，形成凹坑。

Beneath the epithelium, there's another layer called the basement membrane made of tough connective tissue, and below that is the lamina propria which has yet more connective tissue that houses blood vessels, lymphatics, nerves, and immune cells.

在这上皮下面的是另一称为基底膜的结构，坚硬的结缔组织构成，再往下是固有，其包含多结缔组织，容纳了血管、淋巴管、神经和免疫细胞。

The mucosa also has three layers of its own: a layer made of stratified squamous epithelium; a layer of connective tissue, called the lamina propria; and a layer of muscle cells, called the muscularis mucosae.

黏膜本身又三结构组成，一复鳞状上皮，一结缔组织，又叫固有，还有一肌细胞，又叫黏膜肌。

This term stems from the same Latin word that 'lamination' does: 'lamina', meaning 'a thin layer of a material', and it refers to smooth flow in a fluid, where the moving particles stay largely confined to distinct layers.

该术语与“压” 源自同一个拉丁词：“lamina”，意思是“材料的薄”，它指的是流体中的平滑流动，其中移动的颗粒很大程度上被限制在不同的中。

The baleen consists of a row, on each side of the upper jaw, of about 300 plates or laminae, which stand close together transversely to the longer axis of the mouth.

鲸须位于上颌两侧的一排大约 300 个板或薄片组成， 它们横向于嘴的长轴紧密排列在一起。

These hormones signal the subfornical organ and vascular organ of the lamina terminalis, that it's time to drink water.

这些激素向终板下器官和终板血管器官发出信号，提示饮水的时间到了。
