A comparative histologic study of thyroid follicular size and epithelium percentage in certain mammals
Abstract
The size and epithelium percentage of mammalian thyroid follicles were studied by making camera lucida drawings of histologic sections on calibrated graph paper. The average horizontal dimension of 500 follicles per animal was calculated together with the percentage amount occupied by follicular epithelium. With a few exceptions, folicular size tends to increase with increasing body size, while epithelium percentage decreases.
