The renal papilla project into minor calyces which join together to form major calyces which funnel into the renal pelvis.

乳头突入小盏，每2-3个小盏合成大盏；2-3个大盏合并形成漏斗形的盂。

The medulla is made up of 10 to 18 renal pyramids with the base of the pyramids facing the renal cortex and the tips of the pyramids, called renal papilla—or nipples, pointing towards the center of the kidney.

髓质由10-18个锥体构成，每个锥体基底面朝向皮质；尖端乳头，则朝向的中心。

Papillae were only a little longer in lions than in cats, noted Noel and David Hu, an associate professor at Georgia Tech. Their findings were published in Proceedings of the National Academy of Sciences.

乔治亚理工学院副教授诺尔和大卫·胡表示，狮子的乳突只比猫长一点点。他们的研究发现发表在了《美国国家科学院院刊》上。

But if the medication isn't stopped, and the immune cells continue to damage the connective tissue in the interstitium, and those kidney cells can start to die off, called renal papillary necrosis, where the renal papillae are destroyed.

但是如果药物没有停用，这些免疫细胞会继续损害间质中的结缔组织，脏细胞会开始死亡，为乳头坏死，即乳头受损。

Most taste buds are packed deep down between your fungiform papillae — those little projections that make your tongue kinda rough. You can actually see them if you look in the mirror.

大多数味蕾都位于你的真菌状乳突之间——这些小突起会让你的舌头变得粗糙。如果你照镜子，你实际上可以看到它们。

In addition, clogging in the renal papillae can cause necrosis, which can manifest as hematuria and proteinuria - blood and protein spilling out into the urine.

此外，乳头阻塞可引起坏死，表现为血、，即液中的血细胞、质异常增多。

Meanwhile, sandpapery feline papillae are thought to retain saliva during self-grooming, helping cats cool, detangle, and distribute scents

与此同时，猫科动物的沙粒状乳突被认为可以在自我梳理时保留唾液，帮助降温、脱毛和散发气味。

Those papillae are not your taste buds.

那些乳突不是你的味蕾。

And penguins press their backward-facing, centimeter-long, spiny tongue and palate papillae together to secure their slippery catch and direct it into their gullet.

企鹅将一厘米长倒长带刺的舌头和上颚乳突压在一起，以固定滑溜溜的猎物，并将其送入食道。

Tiny structures called papillae cover tongues, facilitating touch and taste sensitivity and more.

舌头上覆盖着被为乳突的微小结构，有助于触觉和味觉的灵敏度等。

When the fur is pushed down flat against the cat's skin, the distance is the same as the length of the papillae, she discovered.

她发现，当猫的皮毛被理顺到皮肤上时，皮毛到皮肤的距离与乳突长度相等。

Rainbow lorikeet papillae bloom into feathery projections that sop up nectar.

彩虹吸蜜鹦鹉的乳突绽放成羽状突起，吸收花蜜。

The hooks are flat, but when cats need them for self-cleaning, they stand up, Noel explains. The scientific name for them is papillae.

诺埃尔解释，钩子平时是平的，只有当猫需要进行自我清洁时，钩子就会倒卷起来。它们的学名是乳突。

Papillae were only a little longer in lions than in cats, noted Noel and David Hu, an associate professor at Georgia Tech.

乔治亚理工学院副教授诺埃尔和大卫·胡表示，狮子的乳突只比猫长一点点。

The Georgia Tech researcher found that the papillae take in liquid.

乔治亚理工学院的研究人员发现，乳突会吸收液体。

A housecat has nearly 300 papillae that hold a small amount of saliva that is released when the tongue presses on fur.

家猫拥有近300个乳突，乳突里含少量唾液，当舌头挤压皮毛时，唾液会被释放出来。

The scientific name for them is papillae.

它们的学名是乳突。

Certain creatures have even adapted to give up  a part of their body until it can regenerate: sea slugs shedding papillae, crabs sacrificing a  claw, geckos shedding a still-twitching tail as a decoy while they escape.

某些生物甚至已经适应放弃身体的一部分，直到它能够再生：海蛞蝓脱落乳突，螃蟹牺牲爪子，壁虎在逃跑时脱落仍在抽动的尾巴为诱饵。

If it wants to have a smooth texture, it flattens out the papillae, so it can acquire a smooth texture to blend in with the sandy bottom of the sea.

如果想要光滑的质地， 就把乳突弄平， 这样它就能获得光滑的质地， 与海底的沙质融为一体。

And they went ahead, worked with us and made the first samples of artificial papillae, soft materials, shown here.

他们继续前进， 与我们合， 制了第一个人造乳突样品，这里展示的是软材料。
