An example would be the descending portion of a biceps curl, causing the biceps brachii muscle to lengthen.

例如，二头肌弯曲下降的部分，让其臂肌伸长。

Those muscle fibers then form larger, string-like bundles called fascicles, which combine to form the larger rope-like muscle organ, like your biceps brachii.

这些肌肉纤维然后形的、像绳子样的，叫，们结合在起形的像绳子样的肌肉器官，就像你的肱二头肌。

Each one of your different skeletal muscles — like your biceps brachii, or vastus lateralis or gluteus maximus — is technically its own organ, made up mostly of muscle tissue, but also of connective tissue, blood vessels, and nerve fibers.

你的每块不同的骨骼肌——比如肱二头肌、股外侧肌或臀肌——严格来说都是自己的器官，主要由肌肉组织组，但也由结缔组织、血管和神经纤维组。
