10.3 The Male Reproductive System Flashcards
also called the male gonad, is the organ that produces spermatozoa
Testis or testicle
is the male reproductive cell, the sperm, male sex cell, or seed and is formed in the testis
Spermatozoon
is the production of spermatozoa, and includes the divisions necessary to produce mature spermatozoa, each with 23 chormosomes
Spermatogenesis
is a thick white fluid containing spermatozoa and the secretions of the other male reproductive glands
Semen
in the male, is the age at which the testes begin to produce mature spermatozoa, with an increase in the secretions of the male sex hormones, the androgens.
Puberty
These stimulate the development of the secondary sexual characteristics: the enlargement of the penis, and the testes, the appearance of the whiskers, the change in voice, and a change in the attitude towards the female
Puberty
the prevention of mature spermatozoa from being discharge from the male organs
Sterilization
any procedure by which spermatozoa are prevented from forming
Castration
it the ability to produce offspring by a spermatozoon uniting with an ovum
Fertility
Male gamete
male reproductive cell, spermatozoon
orchis
Testes
Two glands in the male that produce spermatozoa. 4 to 5 cm or 2 inches in length and lies vertically
Testes
large number of lobules or compartments
Testes
1 to 3 minute coiled tubules
seminiferous tubules
15 to 20 larger tubules
efferent duct
single tube
epididymis
is a sac that is suspended below the pubic arch, anterior to the upper thighs
Scrotum
consists of an expanded end, a constricted neck, a short body and a long tail
Spermatozoon
a single globular gland that is located in the male pelvis below the urinary bladder
Prostate Gland
composed of many secreting tubules that join together to form about 20 small ducts and empties into the prostatic part of the urethra
Prostate Gland
secretes a watery fluid that forms part of the semen
Prostate Gland
are two elongated nodular glands that lie obliquely in the pelvis posterior to the bladder
right and left seminal vesicles
about 7.5 cm or 3 inches in length
Seminal vesicles
consists of a single tubule that is coiled upon itself that secretes a part of the semen
Seminal vesicles
each seminal vesicle tubule ends in an excretory duct that joins the corresponding deferent duct to form the ______
ejaculatory duct
small pea shaped glands lie one on each side of the membranous part of the urethra
Bulbourethral Gland
secretions from part of the semen
