The MUMP is ~1.7 mm long, comprised of a fibrocartilage core called MUMP cartilage, surrounded by two MUMP corpus cavernosum (lie on lateral sides of the MUMP fibrocartilage core), and covered with skin. The MUMP boundary is defined by the MUMP ridge, a groove that encircles the distal glans penis. MUMP EMAPA:36398 TS28
