Columnar snow crystals look like sticks of ice.

柱状冰晶像是冰柱的样子。

He talks about columnar reference frames and how he thinks that's one of the keys to understanding the brain.

他谈到了柱状参考框架以及他是如何认为该框架是理解大脑的一。

These guys can transform into ciliated columnar cells, so they help regenerate and replace damaged ciliated columnar epithelial cells if needed.

它们可以转化为纤毛柱状上细胞，必要时可以替和修复受损的纤毛柱状上细胞。

Finally, there’s an inner ring of luminal columnar cells, which are within the lumen or center of the gland.

最后是一层管腔柱状细胞，位于管腔内或腺体中央。

This causes the epithelium of the lower esophagus to constantly renew, and when it’s replaced by columnar epithelium, that’s called Barrett’s esophagus.

这使得食管下段的上不断更新，当其被柱状上时，叫做Barrett食管。

The endometrium is itself made up of a single layer of simple columnar epithelium, which has ciliated and secretory cells, that sit on top of connective tissue, or stroma.

子宫内膜由单层柱状上构成；单层柱状上有纤毛细胞及分泌细胞，位于结缔组织即基质顶部。

Now the walls of the conducting bronchioles are similarly lined by ciliated columnar cells and mucus secreting goblet cells, as well as a new cell type called club cells.

传导性支气管壁上也有纤毛柱状细胞、分泌粘液的杯状细胞，还有棒状细胞。

The large airways are lined mostly by ciliated columnar cells and a handful of goblet cells which get their name from looking like a wine goblet or glass, and secrete mucus.

大的气道含有大量纤毛柱状上细胞与少数杯状细胞；杯状细胞因形似玻璃杯而得名，且分泌粘液。

On the other hand, adenocarcinoma is the most common type of esophageal cancer in the United States of America, and it originates in the columnar glandular epithelium, most often in the lower third of the esophagus.

另一方面，腺癌是在美国最常见的食管癌类型；腺癌起源于柱状腺上细胞，最常位于食管的下三分一。

Metaplasia refers to the replacement of one mature cell type with another mature cell type: for example, squamous metaplasia of the respiratory columnar epithelium - as evidenced by the metaplastic cough of a smoker.

化生是指一种成熟细胞类型被另一种类型的成熟细胞替。例如，呼吸柱状上的鳞状化生由吸烟者的化生咳嗽证明。

Also, when the epithelium is continuously damaged and replaced, the new epithelium of the lower esophagus is gradually replaced by a single layer of columnar cells, similar to intestinal cells, that are more adapted to withstand the reflux.

此外，当上持续受损并被替换时，食管下段的新上逐渐被单层柱状细胞，类似于小肠细胞，这些细胞更能经受住反流。

The presence of acid in the esophagus can lead to Barrett’s esophagus, which is when the squamous epithelium lining the esophagus is replaced by a columnar epithelium, similar to that of the intestines, that’s better adapted to withstand the acidity.

食管中存在胃酸会导致Barrett食管，即食管的鳞状上细胞被柱状上替，变得很像小肠的上；柱状上是更加适应酸性环境的上类型。
