Abstract
The histology of the carotid body in cat, sheep and rat was re-studied. The Ag technique of Holmes (1951) was used with advantage. Besides ordinary glomus cells a second type was found typically in close association with the vascular supply. Stellate and non-stellate interstitial cells occur. Fibers of the glossopharyngeal nerve expand into an intra-glomerular network in which interstitial cells are enmeshed, thence passing to glomus cells where they end in an intra-cellular reticulum. de Castro''s findings of direct innervation of glomus cells was not confirmed.
