Surface lining of Endometrium is Simple Columnar Epithelium, which extends downwards forming long, tubular Uterine Glands. In Proliferative/Follicular Phase these glands are mainly straight in upper portion of endometrium and branch out in lower portion, because of which numerous glands are seen in cross section (in Basalis layer).  During menstrual cycle, endometrium exhibit morphological changes that are correlated with ovarian functions. These cyclic changes are divided into  Proliferative/follicular Phase Secretory/luteal Phase and Menstrual Phase Important Labels: Endometrium (Functionalis and Basalis Layers) Myometrium (Smooth longitudinal & cross-sectional muscles) Lining Epithelium Uterine Glands Spiral/Coiled Arteries
