Mixed serous and mucous secretory units
(40x objective lens)
This section of the submandibular (submaxillary) gland shows that it contains
a mixture of serous secretory units with basophilic
cytoplasm and mucous secretory units (unstained
cytoplasm) with serous demilunes (basophilic
cytoplasm). Also shown are a septum
of pink-stained connective tissue, coursing at an angle through the right
half of the image, and two cross-sectional profiles of striated
(intralobular) ducts with walls of simple columnar epithelium.
