Dissection of male pelvis from a lateral approach
General view of pelvic contents in situ, pelvic diaphragm reflected
The opening into the pelvis has been somewhat enlarged by the removal of more of the pubic and ischial bones and a small part of the body of the ilium. The obturator fascia has been cut away and the pelvic diaphragm has been split and reflected. Areolar connective tissue has been stripped from the underlying vessels and nerves.
- Periosteum of ilium
- Body of ilium (partially removed)
- Obturator artery (source of two vesical branches)
- Upper pointer: Parietal peritoneum (external aspect) Lower pointer: Ductus deferens
- Obturator nerve
- Iliopsoas muscle (cut off)
- Femoral nerve (cut off)
- Femoral artery and vein (cut off)
- Urinary bladder (external surface)
- Superior vesical artery
- Pectineus muscle
- Transversalis fascia
- Pubic symphysis (left pubic bone cut away)
- Suspensory ligament of the penis
- Glans penis (dissected)
- Upper pointer: Ureter Lower pointer: Pelvic ganglion (note parts of pelvic plexus associated with ureter)
- Sciatic nerve
- Inferior gluteal artery
- Piriform muscle
- Coccygeus muscle (reflected)
- Filaments of pelvic plexus
- Parietal pelvic fascia
- Vesical veins
- Branch of sacral nerve IV to levator ani muscle
- Levator ani muscle (reflected)
- Superior fascia of pelvic diaphragm
- External anal sphincter muscle
- Superior fascia of urogenital diaphragm
- Urethra (opened)
