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

我们眼构支撑是由板致密缔组织板提供。

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.

每个板都垂直放置着产油脂皮脂腺，称为板腺，板有 25 个，下板有 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板，也存在于致密缔组织板中，被称为跗骨板，它也提供骨骼支撑，位于眼后部。

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.

如果眼边缘这些板腺分泌口被堵塞，腺体分泌物开始释放到板和周围眼软组织中，引起炎症反应。
