Structural support to our eyelids is provided by dense plates of connective tissues called tarsal plates.

我们眼睑的结构支撑是由睑板致密的结缔组织板提供的。

Each tarsal plate has vertically placed oil-producing sebaceous glands called Meibomian glands in them, 25 in the upper and 20 in the lower tarsal plate.

每个睑板都垂直放置油脂的皮脂腺，称为睑板腺，睑板有 25 个，下睑板有 20 个。

Another oil-secreting glands called Meibomian glands are also present in the dense connective tissue plates also known as tarsal plates, which also provide skeletal support and are placed posteriorly in the eyelid.

另一种油脂分泌腺体叫睑板，也存在于致密结缔组织板中，被称为跗骨板，它也提供骨骼支撑，位于眼睑后部。

If these Meibomian gland orifices at the lid margin become plugged or blocked, the contents of the glands (meibum) start getting released into the tarsal plate and surrounding eyelid soft tissue causing an inflammatory reaction.

如果眼睑边缘的这些睑板腺分泌口被堵塞，腺体的分泌物开始释放到睑板和周围的眼睑软组织中，引起炎症反应。
