Document Summary
Secretory tissue in the interior of the gland is made up of: connective tissue - this includes fibrous connective tissue of the parenchymal tissue and the fatty tissue of the fat pad. An example of fat pad is illustrated in the image below. Fat pad is required for correct development of the parenchymal components as the ducts branch and grow into the fat pad in the udder of the cow: secretory tissue - this is made up of secretory epithelial cells. These are the cells that produce milk during lactation. These also are part of the parenchymal tissue. Parenchyma: is composed of epithelial structures, in this case ducts and immature lobules, and the connective tissue that is around the ducts and lobules, as well as the connective tissue within the lobules. Secretory tissue in the udder is organized into lobes, with each lobe made up of many lobules.
