KROK 1 2017 – Question 143 · KROK (Medicine) · Histology, Cytology, and Embryology
Presented is the biopsy material of an organ consisting of saccule-shaped rounded structures of varying size. Inside these structures there is a gel-like non-cellular substance - colloid; structure walls are composed of one layer of cuboidal cells that lay on the basement membrane. Between the saccules there is connective tissue with vessels. Name this organ:
- A. Thymus
- B. Parathyroid gland
- C. Pancreas
- D. Thyroid gland
- E. Parotid gland
Hint
Think about which organ stores its product outside the cells, inside closed epithelial spheres, rather than releasing it through ducts or from cords of cells.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
