YES
UNICELLULAR EXOCRINE GLANDS
- The epithelium (B) bordering the lumen (D) is simple columnar
(one layer of columnar cells containing each one oval nucleus located
at the bottom of the cell).
- In this photo, the unicellular glands are goblet cells (A) that
manufacture and secrete mucus (C).
- In this specific case, goblet cells are unicellular glands
because they do not
associate with each other to form secretory units (= multicellular
exocrine glands). They are instead scattered amongst the non secretory cells
of the epithelium and secrete mucus directly in the lumen.
