Answer 1

Answer:

Meibomian glands (often written with a small "m" and also called tarsal glands) are holocrine type exocrine glands, along the rims of the eyelid inside the tarsal plate. They produce meibum, an oily substance that prevents evaporation of the eye's tear film. Meibum prevents tears spilling onto the cheek, trapping the tears between the oiled edge and the eyeball, and making the closed lids airtight.[1] There are about 50 glands on the upper eyelid and 25 glands on the lower eyelid
