The compressed part of the brainstem is called the left cerebral peduncle.

这时干受压的部分称为左脚。

Eventually, this injury of the left cerebral peduncle will result in weakness on the same side of the body as the side of the focal mass effect, also called ipsilateral weakness.

最终，左脚的损伤会导致颅内占位（右）的肌肉无力，即偏瘫。

These masses are also pedunculated, meaning it's attached to a peduncle... or a stalk of tissue, and also gelatinous in consistency as a result of an abundance of ground substance on histology.

这些肿块蒂的，意味着它附着于肉茎（或者一柄组织），由于组织学上的基底物质丰富，它们通常黏附在一起。
