Fig. 2-15. Stereogram of part of the adrenal cortex of Rattus; 

 the cells form a continuum through which blood capillaries tunnel 

 to make contact with each cell. The fibres on the outer (upper) 

 surface represent the connective tissue capsule surrounding the 

 gland; below this, the blood vessels branch freely and then run 

 directly inwards through the main secretory region (zona fascicu- 

 lata) of the gland and anastomose at the inner (lower) surface, next 

 to the medulla (which is not shown). (From Pauly, 1957).
