FIGURE 19.12 | Thyroid Gland and Parathyroid

Gland

This photomicrograph shows parathyroid gland adjacent to the thyroid gland. A
connective tissue septum (3) separates the two glands. Different size follicles
with colloid (1) and follicular cells (2) characterize the thyroid gland.

The parathyroid gland contains the smaller chief cells (4) and oxyphil cells
(5) that are larger and less numerous and exhibit an eosinophilic cytoplasm.

Numerous blood vessels (6) surround the secretory cells in both organs.
