What is the secretion method of the Meibomian glands?

Explanation:
Meibomian glands are modified sebaceous glands in the eyelids that produce meibum, a lipid-rich secretion that stabilizes the tear film and helps prevent evaporation. The secretion method is holocrine: the secretory cells (meibocytes) accumulate lipids, then die and disintegrate, releasing their lipid contents into the duct. Basal cells continually replace the lost cells to maintain gland function. This differs from merocrine secretion (exocytosis of watery fluid without cell loss), apocrine secretion (loss of a portion of the apical cytoplasm), or cytocrine transfer (not a standard gland secretion mechanism).
