Both of these have chordae tendineae coming off of them that tether the valve to the papillary muscles in the left ventricle.

这两种都有腱索，连接到左心室的乳头肌上。

Other potential causes of renal papillary necrosis are chronic use of analgesics, like aspirin, as well as diabetes mellitus, sickle cell disease, and pyelonephritis.

其他肾乳头坏死的潜在原因是长期使药，如阿司匹林、糖尿病、镰状细胞疾病以及肾盂肾炎。

And each cusp looks kind of like a parachute, because it has tiny little strings, called chordae tendineae, coming off of it that tether the cusps to a small muscle called the papillary muscle.

每个尖瓣看起来就像一个降落伞，因为它有的弦，叫腱索；腱索将尖瓣连接在一块叫做乳头肌的肌肉上。

When the heart contracts, that papillary muscle keeps the chordae tendineae taut; and both of these help to prevent regurgitation of blood back into the atrium, allowing it to only flow out the next valve.

当心脏收缩时，乳头肌使腱索绷紧；两者有助于防血液反流到心房，使血液只能从下一个瓣膜流出。

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，这些免疫细胞会继续损害间质中的结缔组织，而肾脏细胞会开始死亡，称为肾乳头坏死，即肾乳头受损。
