THE PARATHYROID GLANDS

The acidophile cells are of similar shape but are provided with 

 a small spherical nucleus, which is very rich in chromatin, and a 

 granular acidophile cytoplasm. The acidophile are less numerous 

 than the principal cells. 



The distribution of the epithelial cells is subject to considera- 

 ble variation. Most frequently they form an almost solid epithe- 

 lial mass, in which capillary vessels are here and there found, the 

 larger blood vessels occupying the coarser bands of the fibrous stro-

ma. In such glands the two cell varieties are either intermingled 

 irregularly, or the acidophile cells may occur in scattered groups 

 which are interspersed among the more numerous principal cells.
