Modes of secretion: merocrine

Exocrine glands release their secretory products by one of three modes of secretion, merocrine, apocrine or holocrine. These pancreatic acinar cells utilize the merocrine mode of secretion. During this process, enzyme-containing secretory granules accumulate at the apex of the cell, fuse with the plasma membrane and discharge their contents by exocytosis into the lumen. No extra-granular cellular contents are lost. 1200x
