But of course it's much more than just a storage tank — it's lined with the same four main layers found through most of the GI tract — the mucosa, submucosa, muscularis externa, and serosa — but it's got a few special modifications.

当然，它不仅仅是一个储存罐。它内衬着与大部分胃肠道相同的四个主要层——粘膜、粘膜下层、外肌层浆膜——但它有一些特殊的修改。

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.

Now, to prevent the hydrochloric acid from the stomach from damaging the intestinal mucosa, enteroendocrine cells also secrete another hormone, called secretin, which stimulates the pancreatic duct cells to secrete water and bicarbonate.

为了避免胃部产生的胃对肠粘膜造成损伤，肠内分泌细胞还可分泌胰泌素；它可以刺激胰腺导管细胞分泌水氢盐。

Beyond the mucosa, there is smooth muscle followed by more connective tissue, and together, these two layers make up the submucosa and this is where the bronchial mucinous glands live.

黏膜层外是平滑肌细胞，之后是更多结缔组织，这两层共同组成粘膜下层，是黏液腺所在之处。

The bladder wall consists of three layers — an inner mucosa, surrounded by a thick muscular layer called the detrusor wrapped in a fibrous, protective outer membrane.

膀胱壁由三层组成——内粘膜，被一层厚厚的叫做逼尿肌的肌肉层包围，这层肌肉层包裹在纤维状的保护性外膜。

Nasal Polyp are fleshy swellings that develop in the lining mucosa of the nose and paranasal sinuses, air-filled spaces, linked to the nasal cavity.

For example, after a dental procedure that leaves a rough tooth surface, or a broken tooth rubbing against the mucosa.

比如，某次牙科治疗使牙齿变面变得粗糙，或者某颗坏掉的牙齿不断摩擦黏膜。

On the other hand, rhinoviruses commonly infect the epithelium of the respiratory mucosa, which lines the nasal cavity.

另一方面，病毒通常会感染腔周围的呼吸道粘膜上皮细胞。

In the layers of the bladder wall are a mucosa layer that has a transitional epithelium, which is stretchy and allows the bladder to distend while maintaining a barrier between urine and the body.

膀胱壁多层结构的粘膜层为变移上皮，变移上皮富有弹性，使膀胱扩张的同时，保证尿液不进入组织液。

Persistent acid reflux damages the esophageal mucosa, causing local inflammation, or esophagitis.

持续性反流会损害食管粘膜，引起局部炎症，即食管炎。

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（包括上皮细胞的内层、固有层），以及粘膜下层，也就是平滑肌所在的地方。

And the inner mucosa is made up almost entirely of mucous cells, which produce a protective coat that keeps the stomach tissues from getting digested along with your lunch.

内层粘膜几乎完全由粘膜细胞组成，粘膜细胞产生保护层，防止胃组织随着你的午餐被消化。

Causes It is caused by dental infection or tooth abscess, involving molars and premolars, as well as submandibular sialadenitis, injuries to oral mucosa, and mandibular fracture.

病因原因是牙齿感染或牙齿脓肿，累及磨牙前磨牙，同时伴有下颌下涎腺炎、口腔黏膜损伤下颌骨折。

When the virus comes in contact with the respiratory mucosa or the skin of a new person, it starts replicating in the epithelial cells.
