Title: Pineal gland (III)
Description:
Pineal gland. (A): Electron microscopy scheme, human. (B): Stain Azan, human. (C, D): Electron microscopy, gerbil.
(A, 1) Capillary, note absence of blood-brain barrier.
(A, 2) Pinealocyte with numerous slender cell processes that contain clear vesicles.
(A, 3) Axons embedded in Schwann-like glia cells.
(A, 4) Interstitial cell (fibrous astrocytes) with glycogen and in close contact with projections of pinealocytes.
(B): Epithelioid pinealocytes (large nuclei with numerous long slender cell processes and interstitial cells (smaller darker nuclei).
Bluish-reddish-stained structures are blood vessels.
(C): Pinealocytes, nuclei often indented and in cytoplasm many mitochondria, well developed Golgi area with small electron-dense grumous bodies (5) (primary lysosomes), numerous small clear vesicles as well as lipofuscin structures (6).
Note subsurface cisterns (7) generally found in excitable neural cells.
(D): Irregularly formed pinealocytes with large lipid droplets, centrally small capillaries without blood-brain barrier (8) (see also A, 1).
Keywords/Mesh: epiphysis, pineal gland, pinealocyte, astrocyte, melatonin, histology, electron microscopy, POJA collection
