The conjunctiva

Conjunctiva is a thin ,translucent , vascular mucous membrane which covers the under surface of the lids and is reflected over the anterior part of the eye ball up to the limbus. It is exposed to dust, wind, heat and radiation and therefore prone to get infected.
It consists of following parts namely,
1. Palpebral
2. Bulbar
3. Fornices
4. Plica semilunaris
It has a two layered structure which includes
1. The epithelium
2. The stroma.
The blood supply is via the anterior and posterior conjunctival arteries and veins. the lymphatic drainage is via the preauricular and submandibular lymph nodes.

  1. So I had a question while I was reading this article. Is this the part of the eye that can get “pink eye”? I was wondering because of the fact that it can get infected because of the exposure to wind, dust and heat. So that made me think that maybe the conjunctiva has something to do with pink eye. Again thank you for posting!
