Inflammation of the Cervix Known as Cervicitis

Description

Centered in the pelvis, the uterus is rendered with its fundus superior and the cervix tapering inferiorly toward the vaginal canal, creating a clear uterine axis from corpus to external os. Bilateral fallopian tubes extend laterally from the uterine cornua, their ampullae curving toward the ovaries, which sit posterolateral to the uterus near the pelvic sidewall. At the lower uterine segment, the cervix is shown enlarged and hyperemic, with diffuse erythema and edema concentrated around the ectocervix and cervical canal. Cervicitis is a clinical diagnosis you often make at the speculum, and the redness and swelling illustrated here match the appearance of an inflamed, friable cervix that may bleed on contact. Common etiologies include Chlamydia trachomatis and Neisseria gonorrhoeae, and the anatomic continuity from cervix to endometrium and fallopian tubes explains how untreated infection can ascend to endometritis and salpingitis, the substrate for pelvic inflammatory disease, tubal factor infertility, and ectopic pregnancy. The cervix is the gatekeeper. This view also supports teaching of cervical motion tenderness on bimanual exam and why mucopurulent endocervical discharge and a widened, tender cervical canal raise concern for an STI-associated process rather than isolated vaginitis. Use this illustration in OB-GYN and reproductive anatomy coursework to anchor discussions of the cervix (neck of the uterus), the relationship of adnexa to the uterine cornua, and the clinical workflow of pelvic exam, NAAT testing, and partner treatment. It also fits patient-facing materials on cervicitis, Pap test timing, and red flags for PID in outpatient gynecology and sexual health clinics.
