There was a silence in which Crookshanks stretched luxuriously flexing his claws.

有一会儿谁也没说话，这时克鲁克山大大地伸了个懒腰，把四个爪子屈曲了一下。

These muscles include the flexor digitorum profundus which flexes the fingers at the interphalangeal joints, and the extensor digitorum which hyperextend them at the metacarpal phalangeal joint.

前臂肌群包括指深屈肌（在指间关节处使手指屈曲）及指伸肌（在掌指关节处使手指过伸）。

If that bending motion decreases the angle of the joint and brings those bones together, like when I bend my arm together, that movement is called flexion.

如果弯曲减少关节的角度，使骨骼结合在一起，就像我弯曲手臂一样，这种为屈曲。

The isometric was an elbow flexion, aka a bicep curl, at maximal contraction held for 3 seconds 10 times at a 20-degree flexion.

精力训练是做肘部屈曲，也就是二头肌弯曲，以极限收缩保3秒，以20度屈曲10次。

For instance, some kinetic and shear forces are significantly dampened, which leads to a loss of detail for buckling effects with traditional techniques.

例如，一些力学和切变力的量被显著抑制，导致传统屈曲效应的细节损失。

Larger fetuses and those that aren't completely flexed have more difficulty making it through the passage.

大一点的胎儿和那些不能完全屈曲的胎儿更难通过产道。

When labor starts, the fetus is normally fully flexed, which means chin is on the chest, and they have a rounded back with flexed arms and legs.

但分娩开始时，胎儿正常情况下完全屈曲，指颏部贴近胸壁，四肢屈曲，背部呈圆形的状态。

One study in 2020 showed that dorsiflexion range of motion, or range of motion of the ankle, had a moderately sized 18.4% increase after using the massage gun on the calf muscles for just 5 minutes beforehand.

2020年的一项研究表明，提前 5 分钟在小腿肌肉上使用按摩枪后，背部屈曲活范围或踝关节活范围增加了 18.4%。

We had an earlier episode on honey buckling, and as every seasoned Fellow Scholar already knows, the link is available in the video description.

我们早期的节目有一集是关于蜂蜜的屈曲性，如同每个经验丰富的学霸知道的，它的链接在视频描述可用。

The most common symptom is weakness or paralysis in the intrinsic muscles of the hand, causing the hand to flex into a claw.

最常见的症状是手内在肌的乏力或瘫痪导致手部屈曲呈爪型。

So normally, in this grid-based approach, if we wish to simulate such a buckling effect, we'll be sorely disappointed because what we will see is that the surface details rapidly disappear due to the inaccuracies in the simulation.

通常情况下，在这种基于网格的方法，如果我们想模拟这样的屈曲效果就会非常失望，因为我们将看到的就是那些由于模拟的不准确而迅速消失的表面细节。

Finally, both the ulnar and median nerves innervate the lumbricals, which are 4 muscles that extend the fingers at the interphalangeal joints, and keep them flexed at the metacarpal phalangeal joints.

最后，尺神经和正神经都支配蚓状肌，这四条蚓状肌能使指间关节的手指伸直，同时掌指关节保屈曲位。

The fingers are flexed at the interphalangeal joints and can't abduct or adduct.

指间关节屈曲，手指无法外展内收。

Think about how hard it'd be to walk when your adductor muscles were always partly flexed, which causes your knees and thighs to constantly touch.

想一下当你的内收肌肉总是部分屈曲时，你的膝盖和大腿会不断地接触，走路会变得多么的困难。

Also though there's fetal attitude, which refers to the way that the fetal body is flexed, not its personality.

另外，胎姿势，指胎儿身体呈屈曲的姿势，不是指性格。

This episode is about simulating a beautiful phenomenon in nature, the buckling and coiling effect of honey.

这一集是关于模拟一种美丽的自然现象——蜂蜜的屈曲和卷绕效果。

This causes all the fingers to stay in a flexed position, so it's also called total claw hand.

这种麻痹会使所有手指呈屈曲状态，也被为“完全爪型手”。

You don't need your brain for newborn sucking, limb flexation in withdrawal from pain.

你不需要你的大脑来吸吮新生儿，屈曲肢体以摆脱疼痛。

That's going to affect shoulder extension, flexion, all these sorts of things.

那将影响肩部的伸展、屈曲等这些方面。

Now, when you're coming into that flexion, say the patient has anterior hip pain.

现在，当你进入屈曲作时，比如患者有前髋疼痛。
