Dissection of male pelvis from a lateral approach
Pelvic organs in situ, close-up lateral view
Attention is focused in this close-up photograph on the central part of the specimen that is shown in the preceding view. Of particular interest is the relation of the pelvic plexus (20) to the ureter (17), bladder (10), prostate (25) and rectum (22).
