肌肉

The brain starts ageing at 20; skin starts to age naturally in the mid-20s; muscles start ageing at 30, but regular exercise can help prevent this; and the voice starts ageing at 65, becoming quieter and hoarser.

研究显示，大脑20岁开始衰老；皮肤25岁左右开始衰老；肌肉30岁开始老化，但常锻炼有助于预防肌肉老化；发音器官则从65岁开始衰老，声音变得轻声细气，越来越沙哑。

Muscles innervated by the motor neurons of a single spinal segment.

由脊髓通过单一前根的所有轴突所支配的部分肌肉或肌肉群，称之。

Third, we are designing muscle-like actuator systems capable of mimicking the dynamic response of normal human muscle.

第三，我们设计类似肌肉的驱动系统，能够模仿一般人体肌肉的动态反应。

As you let your muscles rest and you eat protein, your muscles use a process called protein synthesis and it overcompensates.

但在让你们的肌肉休息，并且补充蛋白质之后，你们的肌肉会进行一种叫蛋白合成的过程，并且开始进行过度地补偿。

HGST offers a complete workout without overexerting yourself. Train virtually every muscle in your body, prevent muscle loss and reduce strain on joints, ligaments and tendons.

高引力运动可有效地减慢老化过程，运动全身肌肉而不会过劳，预防因老化引起的肌肉萎缩和减少对关节、筋腱及韧带的负荷。

For example, since biomechanics requires muscle force against a stationary object to produce bodily movement, muscle contractions must occur; however, the typical person overexerts himself on simple, preprogrammed movements, such as climbing stairs, because of a lack of efficient movement.

例如，生物力学要求肌肉通过对固定物体发力来推动身体的位移，肌肉收缩是必然的。

These loads can be applied by overstretching, when the forces trying to pull a structure apart are greater than the intrinsic strength of the tendon, ligament, muscle, or fascia.

这些负荷也许会来自过度练习，比如尝试过度拉伸肌腱、韧带、肌肉或筋膜（在拉伸中，肌肉更脆弱，因为拉长时，它是放松的）。

The arrows on the diagram to the right show muscles that have their origin locators parented directly to the surface of another muscle rather than to a Maya joint.

图中向右的箭头展示了肌肉的起源locator直接parent到另一块肌肉的曲面，强于parent到一个maya的关节。

SCs cultured from rabbit skeletal muscle can grow and maintain their characteristics in vitro provided appropriate passaging rate and culture condition.

从肌SC稳定的生物学特性看，可以将其作为研究肌肉受损后再生修复的细胞模型，用于检测和研究某些基因和生长因子对肌肉再生和功能恢复的影响。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
