The palpebral margin is thicker than the remainder of the eyelid and cilia grow from the margin.  There are various glands in the region, including '''Moll's glands''' that are modified sweat glands, associated with the cilia.  '''Meibormian glands, Zeis glands''' associated with the cilia and the '''lacrimal glands''' together produce the tear film.
