Abstract:
The microvascutature of the adrenal medulla in the rats and mice were studied by scanning electron microscopy of vascular replicas.There are portal venules between the adrenal cortex and medulla,which are the side branches of the collecting venules of the adrenal cortex and break into capillaries at the adrenal medulla.The adrenal medulla in mice is mainly supplied by these portal venules,and in a rat adrenal medulla,there are also 5—8 medullar arterioles besides the portal venules.Ring-like constrictions appear to be the characters of sphincter at the ending parts of the portal venules,the branches of the medullar arterioles,the collecting venules,and the medullar venules which drain the medullar capillaries as well.The authors believe that the adrenal cortex controls the medulla by the way of the portal venules.
