Male Reproductive Anatomy
Terms in this set (22)
Organ that delivers semen to the female reproductive tract.
External skin sac that houses the testes.
Site of testosterone production.
Cuff of skin encircling the glans penis./
Organs that contribute to the formation of semen. Which is tightly coiled duct lying just outside each testis. Maturation seems to be required for sperm to swim to the egg.
Vas deferens, a passageway from the epididymis to the ejaculatory duct.
Conveys both sperm and urine down the length of the semen.
Produces over half of the seminal fluid, which lie at the base of the bladder, and each has a duct that joins with a vas deferens.
Surrounds the urethra at the base of the bladder; produces a milky fluid.
Produces a lubricating mucus that cleanses the urethra.
Connective tissues sheath enclosing the ductus deferens, blood vessels, and nerves.
process in sexual reproduction in which male and female reproductive cells join to form a new cell
A longitudinal section of a testis shows that it is composed of compartments called lobules, each of which contains one to three coiled.
A microscopic cross section of a Seminiferous tubule reveals that it is packed with cells under going the production of sperm.
During the production of sperm, spermatogonia divide to produce primary spermatocytes. Primary spermatocytes move away from the outer wall, increase in size, and undergo meiosis I to produce secondary spermatocytes.
Each Secondary spermatocytes has only 23 chromosomes. Secondary spermatocytes undergo meiosis II to produce four spermatids, each of which also has 23 chromosomes. Developing into sperm.
Which support, nourish, and regulate the process of spermatogenesis. It takes approximately 74 days for sperm to undergo development from spermatogonia to sperm.
Mature, or spermatozoa have three distinct parts, a head, a middle piece, and a tail. The Mitochondria produces energy( middle part) for the flagellum( the tail) to swim
Ball Cap, which stores enzymes needed to penetrate the egg.
Male sex hormones, the androgens, are secreted by cells that lie between the seminiferous tubules.
The fluid in which sperm leaves the penis.
This tubules are packed with cells undergoing spermatogenesis.
