Endometrial Tissue, Internal View

Description

Endometrial mucosa lines the uterine cavity, and this internal histology-oriented illustration resolves its layered architecture from the luminal surface down to the endometrial myometrial junction. Uterine (endometrial) glands appear as tubular profiles embedded in a cellular stroma, while small arterioles and larger coiled vessels course between glands toward the surface. Superficially, the stratum functionalis occupies the luminal side and transitions inferiorly into the stratum basalis, where gland bases and vascular roots sit closest to the underlying myometrium. Fine stromal detail is prominent. Cyclic remodeling of the endometrium under estrogen and progesterone drives changes in gland morphology and vascular caliber, so a layer-by-layer view helps you correlate normal proliferative or secretory patterns with abnormal uterine bleeding. Pathology often targets specific components: endometrial hyperplasia expands gland density and alters gland to stroma ratio, while endometritis introduces stromal inflammation and disrupts glandular epithelium. Spiral artery anatomy also matters in implantation and early pregnancy loss, and it frames why sampling techniques aim to reach functionalis and basalis without breaching myometrium. Gynecologic pathology and reproductive endocrinology courses use this illustration to teach normal cycling histology alongside common biopsy diagnoses, including hyperplasia, endometrial carcinoma, and the postmenopausal atrophic endometrium. Medical publishers can pair it with figures on dilation and curettage, hysteroscopy, or endometrial biopsy (Pipelle) to clarify what tissue is obtained and from which layer.
