Educational content only — not medical advice.
Anatomy
The pubococcygeus is the intermediate part of the levator ani, extending from the inner surface of the pubic bone to the anococcygeal body and coccyx. In this BP3D model, the muscle is represented across two separate mesh parts (part 2).
Origin & insertion
From the posterior aspect of the pubis to the anococcygeal raphe and coccyx.
Action
Supports pelvic organs, elevates the pelvic floor, and controls urethral and anal closure.
Innervation
Nerve to levator ani (S4) and pudendal nerve branches (S2–S4).
Clinical notes
Pelvic floor rehabilitation targeting the pubococcygeus provides first-line conservative management for postpartum stress urinary incontinence.
