Answer:

<u>b. produce mucus to prevent the eyes from drying out.</u>

Explanation:

Conjunctiva is a<u> mucous membrane which covers the underside of the eyelids, the sclera (the white of the eye) upto the limbus</u> (the junction of cornea/ transparent portion of the eye and sclera).

It contains <u>various mucin glands which produce mucous</u> responsible for moistening the conjunctiva. The various mucin glands present in conjunctiva are

  1. <u>Goblet cells</u>
  2. <u>Glands of Manz</u>
  3. <u>Crypts of Henle</u>

<u></u>

<u>QUESTION:</u>

<u>a. produce tears to lubricate the eyes.</u>

This is the inappropriate answer choice as tears are mostly produced by the lacrimal glands. Only a very small proportion are produced by the conjunctiva.  

<u>b. produce mucus to prevent the eyes from drying out.</u>

This is the<u> correct answer and appropriate choice</u> as mucous from conjunctival glands helps in preventing dryness of eyes.

<u>c. lubricate the eyelids so they do not stick together.</u>

This is the inappropriate answer choice.

<u>d. produce sweat to cool the eyelids.</u>

This is the incorrect answer choice as it is not the function of conjunctiva.
