25
What builds up uterine lining
Estrogen and progesterone from follicularis
26
If there Is no fertilization Then
Corpus luteum -> corpus albicans; estrogen & progesterone levels drop; uterine lining is shed (menstruation)
27
If fertilization Then
1)Pre-embryo implants in the uterine lining; secretes human chorionic gonadotropin (hCG) 2) hCG stimulates corpus luteum to keep secreting progesterone 3) After ~3 months; fetus begins producing estrogen and progesterone & luteum -> albicans
28
Fallopian Tubes(Uterine)
1) suspended by broad ligament 2) Fertilized in Tube 3) Has Infundibulum with Fibrae(brushed feet)
29
Where is the Oocyte fertilized in?
Uterine (Fallopian Tube) then go to the Uterus
30
Parts of the Uterine
1) Infundibulum 2) Ampulla 3) Isthmus 4) interstitial Segment
31
Uterus
Open to Fallopian Tube and Vagina 2) Supports and nourished pre embryo after implantation
32
Parts of the Uterus
Fundus( round top) 2) Body 3) isthmus ( | | ) 4) Cervix ( bottom)
33
Walls of the Uterus
1) Perimetrium 2) Myometrium(middle smooth muscle) 3) endometrium (inner) with Basal layer and Functional layer
34
What layer of the Uterus comes off with menstruation?
The Functional layer of the Endometrium
35
Uterine(menstrual Cycle)
1) Menstrual Phase (1-5 Days) 2) Proliferation Phase (6-14 days) 3) secretory Phase (15-28 days)
36
Menstrual Phase
1st Phases; Day 1-5; function layer is sloughed off
37
Proliferation Phase
2nd Phase; Days 6-14; Functional Layer grows
38
Secretory Phase
3rd Phase; 15-28 Days; Progesterone from corpus luteum increase vascularization and development
39
IF no fertilization Occurs Then?
Corpus luteum degenerates; progesterone drops; menstrual phase begins
40
Vagina
1) Connects uterus to outside of Body 2) Lined w/ non keratinized stratified squamous 3) Hymen (membranous barrier for protection)
41
Female External Genitalia
1) Valva 2) Labia 3) Clitoris
42
Vulva
External Genitalia on female
43
Labia
Thicken folds of skin (major and Minor)
44
Clitoris
Erectile body
45
Mall reproductive Organs
1) Testes (primary) 2) Ducts 3) Tubules 4) Glands
46
Scrotum
Sac that holds testes has Dartos muscle(smooth) with helps with temperature control(elevating /depressing the sac)
47
Testes Produce
Sperm and Testosterone
48
tunica vaginalis
Each testis is covered both anteriorly and laterally by a serous membrane; with a visceral layer and parietal layer
49
Tunica albuginea
Thick; whitish; fibrous capsule called the tunica albuginea covers the testis and lies immediately deep to the visceral layer of the tunica vaginalis.
50
Seminiferous Tubules
IN the testes the internal space has about 250 separate lobules. Each lobule contains up to four extremely convoluted; thin and elongated seminiferous tubules.
51
Interstitial (Leydig) cells
Found outside seminiferous Tubules 2) Produces Testosterone
52
Spermatic Cord
Contains BV; Nerves and VAS DEFERENS(tube for sperm)
53
Sertoli Cells
Produce Sperm
54
Cremaster
A muscle that used to control temperature of sperm with elevation and depression
55
Spermatozoa
Mature Sperm Cell Has Acrosome (protein cap that can penetrate oocytes)
56
Parts of a Sperm
1) Acrosome (protein cap that can penetrate oocytes) 2) Tail 3) Neck
57
Where does Sperm development Take Place
Seminiferous tubules
58
Ducts of testes
1) Rete testes ( receives sperm for seminiferous tubules) 2) Efferent Ductule( connects ret testes to epididymis 3) Epididymis(finishing touches on head body and tail) 4) Vas Deferens ( Tarsales through spermatic Cord; ampulla; merger w/ seminal vesicles to for ejaculatory duct)
59
Open to outside of Body Male
Urethra
60
3 Parts of Urethra
1) Prostatic 2) Membranous 3) Spongy (penile)
61
Accessory Glands to the Testes
Forms Seminal Fluid 1) seminal vesicle( Alkaline fluid 2) prostate Gland (fluid with proteins 4) Bulbourethral ( Cowper's) Gland (mucous)
62
Erectile bodies
1) Corpora cavernosa 2) Corpora spongiosum 3) blood fills venous spaces
63
IS the Erectile body autonomic or sympathic
Autonomic -> para sympathic (fills Blood)
