Genitourinary system. The genitourinary system, or urogenital system, are the sex organs of the reproductive system and the organs of the urinary system. [1] These are grouped together because of their proximity to each other, their common embryological origin and the use of common pathways. Because of this, the systems are sometimes imaged ...
The development of the urinary system begins during prenatal development, and relates to the development of the urogenital system – both the organs of the urinary system and the sex organs of the reproductive system. The development continues as a part of sexual differentiation. The urinary and reproductive organs are developed from the ...
The urogenital opening is where bodily waste and reproductive fluids are expelled to the environment outside of the body cavity. In some organisms, including monotremes, [2] birds and some fish, discharge from the urological, digestive, and reproductive systems empty into a common sac called the cloaca. In most mammals, these three systems are ...
Human physiology. The male external genitalia include the penis and the scrotum. The female external genitalia include the clitoris, the labia, and the vestibule, which are collectively called the vulva. External genitalia vary widely in external appearance among different people. One difference between the glans penis and the glans clitoridis ...
ContraPest is a contraceptive -based pest control tool that causes infertility in brown and black rats. It was originally created to supplement existing rodent control strategies and is formulated as a sweet liquid that appeals to rats. [1] It is developed by the U.S. biotechnology company SenesTech.

The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The urinary tract is the body's drainage system for the eventual removal of urine. [ 1 ] The kidneys have an extensive blood supply via the renal arteries which ...
Muscles of the female perineum. (Urethral sphincter not labeled) The external sphincter muscle of the female urethra is a muscle which controls urination in females. The muscle fibers arise on either side from the margin of the inferior ramus of the pubis. They are directed across the pubic arch in front of the urethra, and pass around it to ...
Sex cords are embryonic structures which eventually will give rise (differentiate) to the adult gonads (reproductive organs). [1] They are formed from the genital ridges - which will develop into the gonads - in the first 2 months of gestation (embryonic development) which depending on the sex of the embryo will give rise to male or female sex ...
