Another low power of parathyroid, showing a somewhat lobulated appearance and considerable adipose tissue intermingled with secretory portions. Slide 56 Parathyroid at higher power, showing that the cells are actually tightly packed epithelial cords. Slide 57 Panoramic view of adrenal gland, showing both cortex and medulla. The boundary between the two is about half way down from the surface. The zone reticularis is darker and narrower.
Medullary cells are larger and bluer in color here.
Slide 58 Higher power of adrenal cortex only. The zona glomerulosa at the top and the.zona reticularis at the bottom have more densely packed cells. Slide 59 Adrenal cortex stained with Mallory-Azan. The c.t. capsule is dark blue. The zona fasciculata is quite wide and pale pinkish yellow.
