This image shows several
exocrine acini and a connective tissue septum (Se).
The acini are rounded structures with a wall made up of a simple columnar
epithelium of wedge-shaped serous secretory cells. The secretory cells: (1)
circular, basally located nuclei (N),
often with a prominent nucleolus (Nu); (2) basophilic
cytoplasm (BC) in the basal half of the cells; and (3) apical cytoplasm
filled with eosinophilic zymogen granules (Zy).
The nuclei of fibroblasts
(Fi) can be seen within the eosinophilic, dense connective
tissue of the septum.
