202 with Mr. Tolar, Wallace Community College Questions
With Complete Solutions
(oogenesis & follicle development) *Before birth*: Correct
Answers oogonia complete their mitotic division
(oogenesis & follicle development) *Childhood*: Correct
Answers primary oocytes *remain in prophase I* & don't
develop further until meiosis resumes after puberty when
specific *hormone levels* trigger initiation of ovarian cycle
(oogenesis & follicle development) *Puberty to menopause*:
Correct Answers Approx. 1x *monthly*, 20-30 primary oocytes
are stimulated to continue development
*squeezes* prostatic secretions Correct Answers During
ejaculation, prostatic smooth muscle contracts, & _______ into
prostatic urethra via several ducts
↓ levels of estrogens & progesterone Correct Answers may
alter female secondary sex characteristics; Breasts, uterus, &
uterine tubes may shrink, while pubic & axillary hair may thin;
Bone density may ↓ & ↑s risk of developing osteoporosis;
Vasomotor signs that include "hot flashes" may occur due to
changes in rhythmic secretion of GnRH by hypothalamus in
response to decreasing blood levels of sex hormones; may
experience many other nonspecific symptoms, including
migraine headaches, backaches, fatigue, & mood swings
,15-30 mins post-ejaculation Correct Answers >semen clot
breaks ↑ due to activity of PSA & other anticoagulants from
prostate
>Sperm cells are gradually released from clot, activated, &
begin their ascent up female reproductive tract
1st polar body Correct Answers >Smaller 1n cell contains
DNA but *little* cytoplasm → called __________ that usually
degenerates
>occasionally proceeds thru 2nd meiotic division forms 2 polar
bodies, *both of which degenerate*
3 Correct Answers Uterine cycle proceeds thru ___ phases
during an avg of 28 days
5 mins post-ejaculation Correct Answers semen coagulates due
to activities of clotting proteins from seminal vesicles &
enzymes from prostate → prevents semen from leaking out of
female reproductive tract
a 2nd polar body & ovum Correct Answers If fertilized,
secondary oocyte will complete 2nd meiotic division & divide to
form ________
A cold scrotum Correct Answers is drawn closer to body
A warm scrotum Correct Answers is relaxed & moves away
from body
ABP & inhibin Correct Answers help regulate spermatogenesis
,Accessory reproductive organs Correct Answers Additional
organs & structures, in both males & females, that contribute to
the functioning of the reproductive system.
Accessory sex glands (of male reproductive system) Correct
Answers are *exocrine glands* that produce *liquid* portion of
semen
acidic pH Correct Answers *Glycogen* in vaginal lumen →
metabolized by bacteria → generates *lactic acid* that helps
maintain ___________ of this region
acrosome Correct Answers develops & covers nucleus & helps
with fertilization of female gametes by releasing digestive
enzymes
After puberty Correct Answers reproductive cycles continue @
regular intervals until 4th or 5th decade when they become
irregular
Aging Effects Correct Answers >Size & weight of testes may ↓
>Number of sustentacular & interstitial cells may ↓
Alleles Correct Answers different variants of the same gene
ampulla Correct Answers Uterine tubes move the oocyte from
*fimbriae* to the *______*; a saclike structure where ductus
deferens terminates
, Antimicrobial chemicals Correct Answers inhibit some
bacterial growth to ↓ risk of infection in female reproductive
system
Antimicrobial chemicals (from prostate) Correct Answers kill
some bacteria including Escherichia coli & Support Structures
antrum Correct Answers primary oocyte & its capsule of
granulosa cells project into ________ (a single large cavity) on a
stalk
apoptosis Correct Answers Most primordial follicles have died
thru this process; programmed cellular death
Associated w/↓'d levels of testosterone Correct Answers
>Gradual ↓ in production of sperm cells
>Depressed mood & fatigue in some
>Loss of muscle mass & ↓ bone density
At puberty Correct Answers hypothalamus becomes less
sensitive to ↓ levels of estrogen & progesterone, & GnRH levels
↑
Atresia Correct Answers >process in which immature follicles
degenerate & are reabsorbed during follicular phase of
menstrual cycle
>process in which immature follicles degenerate & are resorbed
during follicular phase of menstrual cycle
