Dissection of female pelvis from a lateral approach
Exterior of pelvis with femur removed, right lateral view
The right thigh has been detached by disarticulating the femur at the hip joint. Muscles of the gluteal region have been cut off in various ways to demonstrate their interrelations. The obturator externus and pectineus muscles have been completely removed. The periosteum has been stripped from the rami of the pubis and ischium. In succeeding views of this sequence the dissection of the specimen is continued into the interior of the pelvis.
1 . Gluteus medius muscle
2 . Gluteus maximus muscle
3 . Piriform muscle
4 . Obturator internus muscle (cut off)
5 . Sciatic nerve
6 . Ischial tuberosity
7 . Ramus of ischium
8 . Anus
9 . External oblique muscle
10 . Iliac crest
11 . Gluteus minimus muscle
12 . Aponeurosis External oblique muscle
13 . Rectus femoris muscle (origin, cut off)
14 . Iliopsoas muscle (cut off)
15 . Joint capsule of coccyx
16 . Femoral artery and vein
17 . Acetabulum (pointer on ligamentum teres)
18 . Pubic bone
19 . Obturator membrane
20 . Superficial perineal fascia (membranous layer)
21 . Labium majus
