Description
Unlike ordinary urinary system models which are 2-dimensional plaques presenting only half the picture, this fully 3-dimensional replica of the male urinary apparatus and its blood supply is free-standing, permitting study from all aspects.
Molded entirely of non-breakable vinyl polymer, the larger-than-life model consists of 3 parts: 1) the kidneys, adrenals, and blood vessels; 2) a section of the pelvic bones with pubic symphysis, lower portion of the bladder and prostate; and 3) the upper portion of the bladder and prostate. Flexible plastic tubing is utilized for the ureters.
The right kidney is sagittally sectioned revealing its cortex, medulla, pyramids, calyces, pelvis, and the ramifications of the renal artery and vein. Other blood vessels included are the large abdominal aorta and inferior vena cava and their bifurcations, the common iliac, and ultimately the femoral arteries and veins.
Opening the bladder exposes the folded mucosa of its interior, the orifices of the ureters, the trigone, prostatic portion of the urethra, seminal vesicles, ejaculatory ducts, and vas deferens.
Fifty hand-numbered features are identified in the accompanying key. Size, 12 × 19 × 8″ (30 × 48 × 20 cm).
