Smooth muscle in human oviduct. Coloured Scanning Electron Micrograph (SEM) of smooth muscle in the human oviduct. The oviduct or Fallopian tube is the channel which conducts the female egg from the ovary (where the egg is formed) to the uterus where the embryo develops. Bands of smooth muscle (red) are seen in the oviduct wall, arranged circularly and longitudinally. These muscles produce peristaltic waves of motion to push the egg down the oviduct. On their surface are fibroblast cells (yellow), connective tissue cells which secrete thin fibres of collagen (yellow). Magnification: x57 at 6x7cm size.
