Figure 3.

Figure 3

(a) A view of the inner surface of the right pubic origin of the PVM similar in orientation with Figure 2b. Note how thin the semitransparent levator ani (LA) aponeurosis is (i.e. tips of a clamp being visible through the aponeurosis) as it attaches to the superior pubic ramus. This aponeurosis poses a smooth transition from the muscular area of the PVM to the periosteum of the pubic bone. Medially the muscle can be seen to extend closer to the bone than it is laterally where the aponeurosis widens. (b & c) Left lateromedial view of the left PVM origin area seen from outside the pelvis after the lateral pelvic bone was removed to reveal the outside of the aponeurotic levator ani muscle. Note that the medial portion of the left PVM extends to the bone while the more lateral portion has a wide aponeurosis between the muscle and bone. The rectangle shows the view shown in Figure 3b. (Panel c reproduced by permission from Anson (13), p. 474). In this and succeeding figures, closed arrows designate medial origin, and open arrows designate lateral LArch attachment that form the origin of the PVM.
