KROK 1 2017 – Question 45 · KROK (Medicine) · Histology, Cytology, and Embryology
Histological specimen demonstrates a parenchymal organ with cortical and medullary substances.

The medullary substance consists of chromaffin cells and venous sinusoids. What organ can be characterized by these morphological features?
- A. Thyroid gland
- B. Kidney
- C. Adrenal gland
- D. Lymph node
- E. Thymus
Hint
Combine the layered epithelial cords of the cortex with a medulla of chromaffin cells to decide which endocrine organ has both parts.
