-drugs and chemicals - ANSteratogens
-babies receive _________ directly from the mother both during pregnancy and while
breastfeeding - ANSantibodies
-effects of one teratogen" thalidomide - ANSseal like limbs
-never allowed in the US
-teratogen
-used to treat morning sickness and nauseau
-resulted in seal like limbs - ANSthalidomide
-father of biology - ANSaristotle
-observation -> hypotheses -> tests of hypotheses -> results - ANSscientific method
-given placebo
-the variable being tested is absent
-compile results - ANScontrol group
-given drug
-the variable being tested is present
-compile results - ANSexperimental group
-scientists in the field give anonymous reviews, accepting or rejecting the paper for
publication
-the reviewers cannot have any personal or professional relationship with the authors -
ANSpeer review and publishing process
-results become a part of the general knowledge only after they are published in this -
ANSscientific journal
-a system of ideas or misconceptions erroneously regarded as science - ANSpseudoscience
-why is the us government still spending billions of dollars funding scientific research? - ANS
-why can nonscientists have confidence in the information published in the reputable (time
magazine, new york times, smithsonian)? - ANS
-if you had to design a study to investigate the effects of a new drug on human health, what
type of design would you use and how does it work? - ANS
-site of gamete formation (sperm or spermatozoa) and testosterone production
-contains many coiled tubes called seminferous tubules
-located in the scrotum which suspends the ______ outside of the body cavity where they
are kept cooler than normal body temperature - ANStestis (testes)
, -site of sperm cell during maturation
-a chamber sitting on top of each testis
-sperm are stored and mature inside it - ANSepididymis
-during sexual activity, sperm cells travel from the epididymis up the right and left ____
_________ into the body cavity
-loops over the unreters of the urinary system and arrive at the prostate gland
-the sperm then travel into a "tunnel" through prostate gland called the ejaculatory duct -
ANSvas deferens
-produced in seminiferous tubules in testes -> stored in epididymis -> vas deferens ->
urethra - ANSpathway of sperm
-accessory glands
-mucus and fructose
-nourishment for sperm - ANSseminal vesicles
-accessory glands
-thin milky white fluid that contains nutrients for sperm - ANSprostate gland
-accessory glands
-clear lubricating fluid that is alkaline and neutralizes the acid environment of the penile
urethra - ANSbulbourethral glands (cowper's gland)
-sperm from testicles
-fluid from seminal vesicles
-fluid from prostate gland
-fluid from bulbourethral glands (cowper's gland) - ANScomposition of semen
-the pituitary gland produces these - ANSfollicle stimulating hormone (fsh) and luteinizing
hormone (lh)
-follicle stimulating hormone (fsh) -luteinizing hormone (lh) - ANS-hormones that travel
through the bloodstream to the testes where they cause the cells of the seminiferous tubules
to begin producing the male gametes (sperm)
-stimulate the testes to begin production of testosterone
-travels from the testes through the bloodstream where it targets many tissues throughout
the body
-responsible for male secondary sex characteristics
-stimulates growth of many body tissues including muscle, bone, and cartilage, as well as
influencing male sex behavior and aggression - ANStestosterone
-when testosterone levels rise due to the action of FSH and LH
-the testosterone has an inhibiting effect on the pituitary which causes FSH and LH to
decline
-eventually leading to a decline in testosterone production
