Damage to the corticospinal tract causes weakness and problems with voluntary muscle movement below the level of the spinal cord segment.

损伤皮质脊髓束可以导致感觉平面以下的肌肉无力和随意运动障碍。

The way your body moves is through a system called the corticospinal tract, and this is a big part of your motor system.

你的身体运动的方式是通过一个叫做皮质脊髓束的系统，这是你运动系统的重要组成部分。

Brown-Sequard Syndrome is a condition associated with hemisection of spinal cord, which usually damages descending corticospinal tracts, ascending dorsal column tracts and spinothalamic tracts.

脊髓半切综合征，是一种与脊髓半切损伤相关的疾病，通常会损伤下行的皮质脊髓束、上行的脊髓背侧神经束与脊髓丘脑束。

The corticospinal tract is a descending pathway that carries motor information from the brain to different muscles in the body, and it controls voluntary muscle movement.

皮质脊髓束是一条下行通路，携带从大脑向全身肌肉传递的动作信息，控制肌肉的随意运动。

When the corticospinal tract is affected, a person will have problems with voluntary movement, and when the spinothalamic tract is damaged, a person will have problems sensing pain.

当皮质脊髓束受损时，患者会有随意运动障碍；当脊髓丘脑束受损时，患者会有痛觉丧失。

Finally, there's the corticospinal tract, which is a descending pathway that carries motor information from the brain to different muscles in the body, and it controls voluntary muscle movement.

最后是皮质脊髓束：它是一条携带运动信息的下行通路，将运动信息从大脑传输到身体的不同肌肉，控制着肌肉随意运动。

Once your brain receives sensory information, it sends a motor signal down the upper motor neurons through the corticospinal tract in the midbrain, and cross to the opposite side at the medulla before continuing down the spinal cord.

当大脑接收到感觉信息时，它通过中脑的皮质脊髓束向上运动神经元发送运动信号，先交叉至对侧延髓，然后继续下行。
