Meibomian gland location and Function
Answers
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.
Answer:
LOCATION:
Meibomian glands are a type of sebaceous gland located in the tarsal plate of the upper and lower eyelids. They are distinguished by grape-like clusters of acini on the mucocutaneous lid junction, and empty their lipid content (sebum) at this junction in order to coat the ocular surface via holocrine breakdown.
FUNCTION:
abnormal gland function. As we know, the meibomian glands secrete the meibum responsible for the formation of the tear film's outer layer. The meibum aids in reducing the evaporation of tears from the front surface of the eye, increasing the surface tension and forming an optically superior tear meniscus.
