此外，还有一层较厚的肌肉层，称为逼尿肌，能辅助排尿过程，其外层有纤维外膜。

So, moving from the outside of the heart to the inside of the heart: after the epicardium, there's the myocardium, which is the muscular middle layer.

从心脏的外侧到心脏的内部：在心外膜后，有心肌层，即中间的肌肉层。

The inner layer is called the visceral layer, and it gets stuck tightly to the heart itself, forming the epicardium - or the outer layer of the heart.

而内层被称为脏层，它紧紧地贴在心脏上，形成心外膜，即心脏外层。

Meanwhile, the inner serous pericardium consists of an inner visceral layer, or epicardium — which is actually part of the heart wall — and an outer parietal layer.

同时，内部浆液性心包由内部内脏层或心外膜——实际上是心壁的一部分——和外部顶层组成。

Normally, the wall of the entire gastrointestinal tract is made of 4 layers: the inner mucosa, the submucosa, a muscular layer, and an outer layer called the adventitia.

正常情况下，整个胃肠道的壁由4层组成：粘膜层、粘膜下层、肌层和外层（即外膜）。

Finally, there's the tunica externa or outside tunic which is made up of loosely woven fibers of collagen protein that protect and reinforce the blood vessel and anchor it in place.
