QuestionAnswer
climate control of the testes, must be slightly cooler than body scrotum
how many hrs are sperm fertile for 72
male puberty starts at age 12-16
muscular organ at the top of the vagina supported by ligaments and the site menstartion, egg implantation, fetus developement, labor uterus
top of uterus dome shaped fundus
bottom portion extends to vagina will open to 10cm cervix
layer of uterine wall that sheds during period endometrium
how many cm is the cervix 2-5cm
ea 12 cm long, less than 1cm in diameter, site for fertilization in ampulla Fallopian tubes
almond shaped organs, produce ova, secrete estrogen, progesterone ovaries
attainment of mature sexual charactoristics in response to estrogen and progesterone age 10-14 female puberty 1st manarche
female reproductive cycle endometrial cycle (uterus), ovarian cycle (egg)
levels are relatively low during the preovulatory phase of the menstrual cycle, rise after ovulation, and are elevated during the luteal phase progesterone
uterus grows a new, thickened lining that can hold a fertilized egg (endometrium)
secretes a moderate amt of estrogen to inhibit release of GnRH & secretion of LH and FSH; is a visible coll of blood left after rupture of the follicle that secretes progesterone. corpus luteum
is a hormone produced by gonadotroph cells in the anterior pituitary gland. In females, an acute rise of LH ("LH surge") triggers ovulation Luteinizing hormone
regulates the development, growth, pubertal maturation, and reproductive processes of the body.This and luteinizing hormone (LH) act synergistically in reproduction. Specifically, an increase in this secretion by the anterior pituitary causes ovulation. Follicle-stimulating hormone
these are a fam of protiens which include FSH & LH Gonadotropins
what happens during the menstrual phase of the menstral cylce shedding of the lining of the uterus
what happens during the proliferative phase of the menstral cylce estrogen increases
what happens during the secretory phase of the menstral cylce increased progesterone causes the endomertrium to thicken in prep for implantation, estrogen levels drop
During this ovarian cycle, hormonal influences such as LH n FSH; LH surge releases egg from follicle Follicular
During this ovarian cycle, Estrogen levels drop; ovum lifespan is 24hrs ovulation
During this ovarian cycle, day 14-28 after the follicle ruptures and releases the egg, it forms a corpus luteum luteal (corpus luteum secrets progesterone->endometrium to prep for implantation; if no implant ->corpus breaks down)
last menstrual period is dated with certaintly only 1 yr p menstruation menopause
how many pairs of homologous chromosomes in normal human somatic cells 23
how many chromosomes are inherited from each patent 1 chromosome of ea pair
how many pairs of autosomes which control most traits 22
how many sex chromosomes control primarily sex determination 1
total chromosomes 46
is a test to examine chromosomes in a sample of cells, which can help identify genetic problems as the cause of a disorder or disease <40y Karyotyping
may be differerences in number or structure of chromosomes autosomal albormalities
If the chromosome pairs fail to separate properly during cell division, the egg or sperm may end up with a second copy of one of the chromosomes. trisomy (numerical abnormality)
the presence of an extra chromosome 21, which is found in Down syndrome, is called trisomy 21.
Women with Turner syndrome typically have one X chromosome instead of the usual two sex chromosomes. Turner syndrome is the only full ____ that is seen in humans—all other cases of full are lethal and the individual will not survive development. monosomy
cells and organisms are those containing more than two paired (homologous) sets of chromosomes. Polyploid
a single crease across the palms (Simian crease),flat facial profile,tongue may appear large in relationship to the mouth,(upward slant of eyes) characteristics and physical symptoms of Down Syndrome
a genetic d/o that affects a girl's dev caused by a missing or incomplete X chromosome.They are short,& their ovaries don't work properly.Most are infertile;n at risk for health prob like high BP,kidney prob,DM,cataracts,osteoporosis & thyroid prob. Turner syndrome (X45)
Short, "webbed" neck with folds of skin from tops of shoulders to sides of neck Low hairline in the back Low-set ears Swollen hands and feet Turner syndrome
a genetic condition that results when a boy is born with an extra copy of the X chromosome,affects testicular growth,produce little or no sperm Klinefelter syndrome (trisomy XXY)
an autosomal dominat d/o;growth hormone deficiency have a slow or flat rate of growth, usually less than 2 inches per year. The slow growth may not appear until a child is 2 or 3 years old. Pituitary dwarfism
uniting sperm and ovum form a zygote (46 chromosomes),takes place in the ampulla of fallopian tube fertilization

two offspring produced in the same pregnancy and developed from one oocyte (_____) monozygotic
A fertilized ovum up to 14 days old, before it becomes implanted in the uterus. preembryonic developement
preembryonic developementninner cell mass is called _____which form embryo and amnion bastocysts
preembryonic developement outer cell mass is called ______ which form placenta and chorion. trophoblasts
begins to form at implatation from the chorion, maternal portion, fetal portion, attached to mom, rough red texture placenta (shiny gret surface on fetal side)
placenta functions; produces _____, protects ______,seperates _______, & Metabolic functions like resp,nutrition,excretion,storage. hormones (progesterone), fetus from immune attack by mom, barrier separates maternal n fetal blood.
teratogens (etoh,drugs, infections, bacteria)can all pass to fetus via placenta
which stage is most vulnerable period due to rapid growth of all organs and structures forming. embryotic stage (1st 8 wks)
stalk attaches to schultz of placenta, 2 arteries, 1 vein surrounded by whartons jelly, provides circulation and oxygen umbilical cord
this helps maint temp, permits symmetric growth n development, cushions amniotic fluid
what are the three shunts in the circulatory system in fetal life ductus venous (umbilical vein to inferior cava), ductus artery ( pulmonary to aorta), foramen (opening between L & R aorta)
is a blood vessel connecting the pulmonary artery to the aortic arch. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs. ductus arteriosus
shunts approximately half of the blood flow of the umbilical vein directly to the inferior vena cava. Thus, it allows oxygenated blood from the placenta to bypass the liver. ductus venosus
