Lacrimal Gland

Sunday, April 12, 2009

The lacrimal glands are a pair of compound tubuloalveolar glands which secrete the aqueous layer of the tear film. They are located in the upper, outer portion of each orbit.

The lacrimal glands are made up of many lobules separated by connective tissue, each lobule contains many acini. The acini contain serous cells and produce a watery serous secretion. The lacrimal gland proper is highly developed as a complex tubuloalveolar structure with several ducts which pour their copious fluid into the outer, upper part of the conjunctival sac.
