What is the purpose of the perineum?

Where is the urogenital diaphragm?
The urogenital diaphragm, also called the triangular ligament, is a strong, muscular membrane that occupies the area between the symphysis pubis and ischial tuberosities and stretches across the triangular anterior portion of the pelvic outlet. The urogenital diaphragm is external and inferior to the pelvic diaphragm.
Which part of the urethra is within the urogenital diaphragm?
The membranous urethra lies within the urogenital diaphragm surrounded by the sphincter urethrae muscle and is the least dilatable portion of the urethra. The prostatic and membranous urethra are lined with transitional epithelium. The spongy (cavernous) urethra is enclosed in the corpus spongiosum.
