This helps differentiate it from diseases that affect the motor cortex or corticospinal pathway.

这一点使其区别于运动皮质或皮质脊髓通路病变。

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。

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。

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。

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。

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.

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