Reproductive System Flash Cards

The reproductive gland in a male vertebrate

The external sac of skin enclosing the testes in most mammals.

The main duct through which semen is carried from the epididymis to the ejaculatory duct.

Either of the paired ducts in males, formed by the junction of the seminal ducts with the vas deferens, that pass through the prostate and empty into the urethra, and through which semen is ejaculated.

A viscous whitish secretion of the male reproductive organs, containing spermatozoa and consisting of secretions of the testes, seminal vesicles, prostate, and bulbourethral glands. Also called seminal fluid or spermatozoa.

Either of a pair of pouchlike glands situated on each side of the male urinary bladder that secrete seminal fluid and nourish and promote the movement of spermatozoa through the urethra.

A gland in male mammals surrounding the urethra at the base of the bladder that controls release of urine from the bladder and secretes a fluid which is a major constituent of semen.

Either of two small racemose glands that are located below the prostate and discharge a component of the seminal fluid into the urethra. Also called Cowper's gland.

The process of producing sperm

Any of the tubercles of the testes which produce spermatozoa

A long, narrow, convoluted tube, part of the spermatic duct system, that lies on the posterior aspect of each testicle, connecting it to the vas deferens.

Any of the cells of the gonads in male organisms that are the progenitors of spermatocytes.

A primary spermatocyte divides into two secondary spermatocytes, which in turn divide to form the spermatids.

Any of the four haploid cells formed by meiosis in a male organism that develop into spermatozoa without further division.

Any of the elongated, striated cells of the seminiferous tubules of the testis, to which spermatids attach for nourishment during spermatogenesis.
