Dissection of female pelvis from a lateral approach
Pubis, ischium and external genitalia, close-up view of right lateral aspect
The lower portion of the dissection shown in the preceding view is displayed in this close-up photograph. The superficial fascia of the perineum has been dissected. The membranous layer of the fascia (25) consists in part of a fan-like series of fibrous bands which radiate into the labium majus from a bony attachment along the inferior ramus of the pubic bone.
