In this image, the right image shows a squamo-columnar junction. If there were the Z-line, the left side of the image (F) would be located to the Z-line and would be the , whereas the right side of the image (S/K) would be to the Z-line and would be the . If this right image were the pectinate/dentate line, the left side of the image (F) could be the , and the right side (S/K) would be the . The tissue on the left image would be found in the , where the structures shown as V are called villi. These villi are comprised of epithelium whose stem cells are found at the base or deepest part of the crypt, shown as . Just deep to the crypt is the smooth muscle layer called muscle, followed by muscle and finally .
