Fallopian tube. Light micrograph of a transverse section through the ampulla of a fallopian tube, or oviduct. The fallopian tubes carry the egg from the ovary to the uterus (womb). The central lumnen (white, upper centre) is surrounded by a mucosa that contains ciliated columnar epithelium, which helps the movement of the egg along the oviduct. Surrounding this are layers of circular and longitudinal muscle (light red) that contract and relax to push the egg along the oviduct. Magnification: x4 when printed at 10 centimetres tall.
