So, suppose a person was stabbed in the neck, and had a complete right hemisection of the spinal cord.

现在假设一名患者被颈部，彻底损右侧髓。

The hemisection damages neural tracts in the spinal cord that carry information to and from the brain.

这种半切损髓中为大脑传递信息神经束。

Now, in clinical scenarios, a complete right side or complete left side hemisection is pretty rare.

在临床上，完全右侧或完全侧半切损是非常罕见。

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.

髓半切综合征，是一种与髓半切损相关疾病，通常会损下皮质髓束、上髓背侧神经束与髓丘脑束。

That's why, most of the time, individuals with Brown-Sequard Syndrome will only present with an incomplete hemisection, and some sensory or motor problems, depending on which tracts are damaged.

这就是为什么在大多数情况下，髓半切综合征患者仅表现出不完全半切损，即根据受损神经束而不同部分感觉和运动症状。

In Brown-Sequard syndrome, a vertebral bone fracture or any kind of penetrating trauma, like a gunshot injury or stab wound in the back can lead to the hemisection of the spinal cord.

髓半切综合征，即椎骨折或有任何穿透性创，比如火器、背部，造成髓半侧损情况。

Besides those three tracts, very rarely, a hemisection of the spinal cord above the T1 spinal level can also damage the sympathetic chain that runs alongside the spinal cord and supplies the facial region.

在很罕见情况下，除上述三条神经束，髓在胸1水平以上半切损还会损沿髓走、支配对应面部区域交感神经。
