d/ GAMETE
a mature male or female germ cell usually possessing a haploid chromosome set and capable of initiating formation of a new diploid individual by fusion with a gamete of the opposite sex -- called also sex cell
d/ HAPLOID
having the gametic number of chromosomes or half the number characteristic of somatic cells
d/ DIPLOID
having the basic gametic chromosome number doubled
d/ SPERMATOGENESIS
meiosis that occurs in the testes
d/ OOGENESIS
meiosis that occurs in the ovaries
capsule outside the testes
d/ TUNICA ALBUGINAE

sections (like a grapefruit) of the testes
how many LOBULES are there?
250 or so each testes
d/ SEMINIFEROUS TUBULE
30' long tube inside lobule where spermatogenesis occur
d/ SPERMATOGENSIS
male version of gametogensis (by meiosis), male spermatogonia develop into mature spermatozoa
d/ INTERSTITIAL CELLS and ANDROGENS of seminerferous tubules?
surround tubules and secrete hormones called Androgens
d/ ANDROGENS
male sex hormones
d/ TESTOSTERONE
the main androgen responsible for inducing and maintaining male secondary sex characteristics
d/ SCROTUM
outside the body cavity that contain the testes
What is the most site for male Cancer?

50-60 yes 80-90 no
Fx of PROSTATE GLAND
i1 - Secretes 50% of seminal fluid 2 - Makes semen alkaline
What is the benefit of the semen being alkaline?
Alkaline fluid makes semen more motile
How many columns of erectile spongy tissue are in Penis?
3
d/ PASSIVE HYPEREMIA
d/ PARASYMPATHETIC NS affect during errection?
during sexual excitement

LEss than 20 million
Menstraul Cycle is also called the __________?
Estracycle

28 day cycle that involves regular
d/ 2 Layers of the uterus
stratum basilum and stratum functionalis
Which layer of the emdometrium does the fertilized egg bury itself?
Stratus Functionalis
d/ OVULATION
release of egg by the ovary
d/ MENSTRUATION
ireleae of ticked endometrial layer
What hormone is responsible for Menses?
Reduction in Progesterone level is responsible for Menses onset
d/ MENARCHY
1st period cycle at puberty
What hormones are responsible for the onset of Menarchy?
FSH and LH
d/ MENOPAUSE
iAt approx 45-50 yrs menstrual cycle ceases. This is due to lack of ovarian secretion called estrogen
MENSTRUAL CYCLE occurs in the ____________
while the OVARIAN CYCLE occurs in the ovaries
d/ OOCYTE
an egg before maturation
How many OOCytes does a baby girl have?
1000's
d/ FSH fx
In both males and females
d/ LUTEINIZING HORMONE
This 'LH surge' triggers ovulation hereby not only releasing the egg
d/ Day 1 of the Menstrual Cycle
little activity except FSH increases
d/ Day 1-5 of Menstrual Cycle
1 - Stratum Functioalis is lost 2 - FSH reaches peak 3 - primary follicle become 20 secondary follicles 4 - Estrogen increases (fr follicles)
d/ Day 6-13 pre-ovulatory phase
1 - one Graafian follicle will surviv 2 - Edometrium thickens due to estrogen 3 - FSH declines 4 - LH increases and peaks on day 12-13
d/ Day 14 Ovulation
Follicle releases egg an becomes Corpus luteum (yellow body) and secretes Progesterone (for 10 days)
Fx of PROGESTERONE
1 - maintain endometrium (no menstruation) 2 - Inhibit FSH (so wont start a new follicles)
d/ what Hormone is used for birth control
Progesterone b/c it stops menstruation
d/ day 14-24 if no fertiliation occurs
i1 - Corpus Luteum atrophies in 10 days (day 24) 2 - on day 24 Progesterone stops thf menstruation starts and FSH is secreted again
d/ day 19-24 if fertiliation does occur
