HUMAN SUPRARENAL BODY. (Figs. 135 and 136) 



SECTION OF A SINGLE LEAFLET, CUT TRANSVERSELY TO THE 



CENTRAL VEINS. STAINED WITH H.EMA- 

 OBSERVE: TOXYLIN AND EOSIN. 



(L.) 



1. Section of arterial twigs on the border of the leaflet. 



2. The convergence of the parenchyma toward the center. 



3. The large and thin- walled central veins. 



4. The small size of the parenchymatous areas on the outer 

 borders and their elongation within, making the zona glomeru- 

 losa and the zona fasciculata respectively. 



5. Distinguish the zona reticularis next to the medulla. 



FIG. 135. VERTICAL SECTION OF A SINGLE LEAFLET OF THE SUPRARENAL 

 BODY. STAINED WITH H^EMATOXYLIN AND EOSIN (X 60). 



A. Fibrous tissues surrounding and connecting the leaflets. 



B. The outer portion, consisting of small compartments the so-called zona glomerulosa. 



C. The central elongated cell-compartments and medulla. 



D. Large, thin-walled central veins. 



E. Arteries ramifying in the outer fibrous tissue which supply the parenchyma.
