The urinary bladder forms from the urogenital sinus. The uterus is primarily supported by the pelvic diaphragm, perineal body, and urogenital diaphragm. As phallus elongates, it pulls forward urethral folds that surrounds urogenital sinus together. It resides on squamous epithelium of the urogenital tract. The lower third is supported by the perineal body, or the urogenital and pelvic diaphragms. Mucus is a normal protective layering around the airway, eye, nasal turbinate, and urogenital tract. It can also lead to cardiac and urogenital malformations. The urethra typically opens into a common channel with the vagina (i.e. urogenital sinus). At week seven, the urorectal septum forms and separates the rectum from the urogenital sinus. It represents the distal end of the urogenital sinus of the embryo. The lower burner relates to the organs below the abdomen and the urogenital functions. The middle third of the vagina involves the urogenital diaphragm. It is bordered superiorly by the superior fascia of the urogenital diaphragm. The urogenital sinus may be divided into three component parts. It is estimated that 276 million new cases of urogenital infections occur each year.
