Transected Section of the Uterus

Description

Presented in an oblique three-quarters view, this transected uterus is oriented around the uterine body, with the thick myometrium forming the dominant outer wall and the endometrium lining the lumen toward the center. The uterine cavity appears as a narrow, slit-like space within the fundal and corporal contour, framed medially by endometrial mucosa and peripherally by concentrically arranged smooth muscle. Along the external surface, the perimetrium (serosal covering) defines the outer boundary where it would reflect onto adjacent pelvic structures. Spatially, the endometrium lies internal to the myometrium, and the cavity sits centrally within the uterine corpus. This cross-sectional morphology is the quickest way to teach the layered architecture that drives both uterine physiology and pathology. Myometrial thickness and symmetry matter when discussing leiomyomas (fibroids), adenomyosis, and postpartum uterine atony, all of which alter the relationship between the muscular wall and the endometrial stripe. The narrow uterine cavity also contextualizes why intrauterine pathology can present with abnormal uterine bleeding while remaining occult on gross external inspection. Form matters. Use this artwork for reproductive anatomy and histology courses when you want students to connect gross uterine form to the endometrium and myometrium seen on microscopy, and for gynecology texts explaining hysteroscopic corridors, dilation and curettage, or the anatomic basis of endometrial ablation. It also supports patient-facing diagrams in infertility and abnormal uterine bleeding clinics by clarifying where the uterine lining sits relative to the uterine wall.
