They are part of the intralobular duct.
They have the thinnest epithelium of any part of the duct system, and the epithelium is usually classified as "low" simple cuboidal.[1]
They are found in:
- the pancreas[2][3][4]

A cell is classified as merocrine if the secretions of that cell dump directly into the lumen.
..... Click the link for more information.Apocrine is a term used to classify exocrine glands in the study of histology. Cells which are classified as apocrine bud their secretions off through the plasma membrane producing membrane bound vesicles in the lumen.

Holocrine secretions are produced within the cell followed by the rupture of the plasma membrane, thus releasing the cellular contents into the lumen.
