male reproductive system
Question | Answer |
---|---|
the male gonads or sex cells | Testes |
tubules producing sperm cells | seminiferous tubules |
cells producing testosterone | interstitual cells |
process of sperm formation | spermogenesis |
number of chromosomes | 46 |
type of cell division forming primary spermatocytes | meiosis |
type of cell divison forming sperotids | meiosis |
number of chromosomes in each spermotid | 23 |
cell formed from each sperotid | sperm |
provides mobility for a sperm | prostate gland |
tubule were sperm cells mature | epididymis |
secrete fluid neutraling acidity of urethra prior to ejaculation | bulbourethral |
secrete fluid containing fructose | seminal vesicle |
secretes fluid activating swimming movements of sperm cells | prostate gland |
mixture of glandular secretions and sperm cells | semen |
contains testes outside the body | scrotum |
temperture required for testes for production | 95.6 |
male organ that is inserted in the vagina for sexual intercourse | penis |
erectile tissue in penis surrounding urethra | corpus spongiosum |
two dorsal columns of erectile tissue in penis | corpora cavernosa |
sheath of skin covering the glans penis | prepuce |
sexual stimulation causes the parasympathetic nerve impluses to | dialate |
during male sexual stimulation what dialates | the arterioles |
what constricts | venules |
what gland neutralizes the ph in the urethra | bulbourethral |
The male sex hormone is | testosterone |
what secretes the gonadotropin-releasing hormone | hypothalamus |
what release FSH and LH | anterior pituitary |
hormone stimulating testosterone secretion by the testes | LH |
What 2 hormones act together to to stimulate spermatogenesis | FSH and LH |
stimulates maturation of male sex organs | testosterone |
stimulates development and maintenance of secondary sex characteristics | testosterone |
hormone that triggers onset of puberty | FSH |
hormone stimulating release of FSH and LH | GNRH |
what are the secondary sex characteristics in males | broad shoulders, muscle development, metabolic rate, enlargment of the larynex, growth of body hair, deepening of the voice |
produces female sex cells | ovaries |
recieves penis in sexual intercourse | vagina |
holds embryo/fetus during a pregnancy | uterus |
carries secondary oocyte towards the uterus | ovary |
narrow space between labia minora | vestibule |
birth canal | vagina |
what are the gonads | the ovaries and testes |
what is a gamete | a sex cell-either sperm or ova |
the seminiferous tubules are lined with what | germinal epithelium |
what is spermatogenesis | process that produces sperm |
the outermost cells of a seminiferous tubles are | spermatogonia |
what are the accessory ducts of the male reproductive system | epidiymis, vas deferens, ejaculatory duct and urethra |
accessory glands | seminal vesicles, prostate and bulbourethral |
whats the function of the testes | seminiferous tubules produce sperm and interstitual cells secrete testosterone |
function of the epididymis | site of sperm maturation, temp storage, carries sperm to vas deferns |
function of vas deferns | carries sperm to ejaculatory duct |
function of ejaculatory duct | caries sperm from the seminal vesicle to the urethra |
urethra | carries semen to the outside body |
bulbourethral | secretes watery fluid that neatralizes ph in the urethra |
seminal vesicle | secrete alkiline fluid containing nutrients for sperm |
prostate | secreates alkiline fluid that activates mobility of sperm |
scrotum | contains and protects testes |
penis | sensory nerve endings, inserted into vagina during sexual intercourse. |
What is the function of LH | promotes growth of interstitual cells of the testes and stimulates the secretion of testosterone |
