肌外膜、肌束膜和肌内膜与筋膜是什么关系？

1.      A skeletal muscle refers to multiple bundles of cells called muscle fibers (fascicles). The fibres and muscles are surrounded by connective tissue layers called fasciae.

骨骼肌是指多个肌细胞束（被称为肌束）。纤维和肌肉被称为筋膜的结缔组织包裹。

2.   Connective tissue is present in all muscles as fascia. Enclosing each muscle is a layer of connective tissue known as the epimysium; enclosing each fascicle is a layer called the perimysium, and enclosing each muscle fiber is a layer of connective tissue called the endomysium.。

结缔组织存在于所有的肌肉中，被称为筋膜。包裹每块肌肉的一层结缔组织称为肌外膜；包裹每个肌束的一层结缔组织称为肌束膜，包裹每个肌纤维的一层结缔组织称为肌内膜。

问题：肌外膜、肌束膜和肌内膜与筋膜是什么关系？
