Q

function of cremaster and dartos muscles, and importance?

A

cremaster- lowers and raises testis in order to control temp
dartos- contracts with temp and during excitement, fear, anxiety, closer to body
importance is to maintain 1-3 degrees below body temp for sperm production

23
Q

function of spermatogonia and spermatocytes?

Study These Flashcards
A

undergo mitosis and meiosis for spermatogenesis to form spermatozoa

24
Q

function of nurse/sertoli cells?

Study These Flashcards
A

to provide blood-testes barrier, secrete inhibin, support developing sperm cells

25
function of interstitial cells
produce testosterone
26
function of ovary?
produces oocytes; secretes estrogen and progesterone
27
function of fimbriae?
creates currents that pull oocyte into uterine tube
28
function of uterine tubes?
conveys oocyte to uterus; optimal site of ferilization
29
function of uterus?
implantation, placenta formation and fetal development occur here
30
function of cervix?
entrance to uterus; dilates from 1mm to 10 cm during childbirth
31
function of clitoris?
developmental homologue to penis; sexual arousal
32
function of labia minora?
hairless lips of flesh that flank vaginal opening
33
function of labia majora?
flank vaginal opening, lateral to labia minora (have hair, sebaceous and apocrine sudoriferous glands)
34
vagina function?
receives penis, birth canal
35
vestibular glands function?
secrete mucus to lubricate vagina
36
what does the fimbriae have that helps sweep the oocyte?
cillia (pseudostratified ciliated columar)
37
where is the optimal site for fertilization to occur?
fallopian tube
38
what 2 hormones regulate the ovarian cycle?
FSH and LH
39
main steps in the ovarian cycle?
follicle cells secrete estrogen, egg enters uterine tubes (ovulation), corpus luteum forms and secrestes progesterone and estrogen to maintain pregnancy, degenerates if no implantation
40
primary functions of estrogen?
thickens endometrium when levels are high, surge of LH occurs when levels are high maintains sex organs, maintains secondary sex characteristics
41
uterus is composed of three layers- outer perimetrium, middle myometrium, inner endometrium. what layer of the endometrium is shed?
functional zone
42
which layer of the endometrium generates new endometrial tissue?
basilar zone
43
what type of muscle is the myometrium made of?
smooth muscle
44
what 2 hormones regulate the uterine cycle?
estrogen and progesterone
45
what are the 3 phases of the menstrual cycle?
menstrual, proliferative, secretory
46
location of foramen ovale?
opening connecting right and left atria
47
location of ductus arteriosus?
connects pulmonary trunk to aorta
48
location of ductus venosus?
connects umbilical vein to inferior vena cava
49
deoxygenated blood in the fetal r. atrium can go into the right ventricle or go directly into the left antrium via what small hole?
foramen ovale
50
where is fetal blood oxygenated?
placenta
51
oxygenated blood coming from the placenta is delivered via?
umbilical veins
52
is blood in the umbilical arteries deoxygenated or oxygenated?
mixed
53
major events of first trimester?
fertilization, implantation, gastrulation, all major organ systems begin developing
54
major events of second trimester?
growth and development of organ systems
55
major events of third trimester?
organ systems complete development, fetus gains weight, myelination
