Abstract
De Castro described small islands of cells near the crotids in the dog and cat which have the structure and innervation of chemoreceptors. A modified silver nitrate reduction method was used to investigate the presence of glomus tissue in the human carotid sinus region and to determine the innervation and microvascular arrangements of such tissue. Three of 60 cadavers showed, in the adventitia or in the adipose tissue from the human carotid sinus region, small islands of tissue richly and typically vascularized and with nerve endings contacting cells like the tissue of the principal carotid body. In 2 of the cases such miniglomera were single but in the 3rd there were several all on the same side.
