Q

Primary oocyte

A
  • Produced after oogonia completes mitotic division
  • then begins first meiotic division and stops at prophase I
  • does not complete meiosis until puberty
  • has zona pellucida and granulosa cells

Q

Secondary oocyte

A
  • Is created when first meiotic division is complete, just before ovulation
  • start to show vesicles and contain theca interna, theca externa
  • secondary oocyte and polar body are created due to unequal Division of cytoplasm
  • begins second meiotic division and stops at metaphase II

Q

Fertilization

A

When sperm and egg bind together

  • sperm binds to plasma membrane - penetrates zona pellucida
  • creates a perivitelline space
  • nuclei of sperm and secondary oocyte combine

Q

Zona pellucida

A

Clear material surrounding primary and secondary oocytes

  • is a second cell membrane
  • formed when second later if granulosa cells develop
  • when egg is fertilized the zona pellucida turns into a perivitelline space, preventing over sperm to enter

25
Perivitelline space
Turns zona pellucida into perivitelline space when sperm enters oocyte cytoplasm. Preventing other sperm to enter
26
Secondary follicle
* fluid filled vesicles form around granulosa cells | * theca interna and externa develop around granulosa cells
27
Mature follicle (graafian follicle)
* cumulus mass of granulosa cells forms around primary oocyte * Antrum- a single chamber of combine fluid filled vesicles
28
Theca interna
* surround granulosa cells | * participate in synthesis of ovarian hormones
29
Theca externa
Connective tissue that merges with the stroma of the ovary
30
Atresia
Degenerate follicles that don't reach maturity or ovulation
31
Corpus luteum
* is left over follicle, after ovulation * granulosa cells turn into luteal cells * divide and enlarge * produce progesterone after ovulation
32
Corpus albicans
Is a degenerative corpus luteum
33
Uterine tubes (Fallopian tubes)
* ovary to uterus | * located at the superior margin of broad ligament
34
Uterine serosa
* Outer layer of uterine tube | * formed by peritoneum
35
Muscular layer
* Middle layer of uterine tube | * consists longitudinal and circular smooth muscle cells
36
Mucosa
* inner layer of uterine tube | * consists if mucous membrane of ciliated columnar epithelium
37
Uterus is defined by three parts:
1: fundus 2: body 3: cervix
38
Perimetrium
* Serosa layer | * peritoneum that covers the uterus
39
Myometrium
* mid layer * muscle layer * smooth muscle * makes if majority if uterine wall
40
Laminate propria
The layer of connective tissue in the endometrium layer
41
Basal layer
* deepest part of the lamina propria | * continuous with the myometrium
42
Function layer
Second layer of the endometrium •Consists of most of the lamina propria & •endothelium: a thick superficial layer
43
Spiral arteries
* in lamina propria | * supply blood to functional layer
44
Mammary glands
* sweat glands | * organs if milk production
45
Lobes
* make up mammary, consisting of 15-20 of these | * one lobe contains multiple glands
46
Lactiferous duct
* each lobe containing own duct | * each opens independently
47
Lactiferous sinus
* just under surface of nipple | * lactiferous ducts enlarge to form sinus, where milk accumulates
48
Lobules
Subdivisions of lobes | •into smaller ducts
49
Alveoli
Secratory sacs created by expanding ducts | •surrounded by myoepithelial cells
50
Myoepithelial cells
Mesh like network surrounding alveoli that contract to expel milk •have contractual properties
51
Areolar glands
Rudimentary mammary glands | •secretions from glands prevent chafing
52
What kind if tissue makes up a breast?
Adipose tissue
53
What makes up the cervical canal and what is it useful for?
* columnar epithelial line the cervical canal producing mucous * acts as a barrier to keep things from passing through the vagina
54
Menses
Mild hemorrhage causing the shedding of the epithelium/functional layer •in response to low progesterone levels •sloughs off due to lack of blood
55
Menstruation
Clinical changes in sexually mature non-pregnant females, that cumulate in menses
56
What is the time between menses and ovulation called?
The proliferative (follicular) phase
57
What is the time after ovulation and before menses called?
Secretory (luteal) phase | Bc. Of existence of corpus luteum
58
What is an ovarian cycle?
The process that occurs in ovaries of mature non-pregnant women during the menstural cycle
59
FSH
* Stimulates the anterior pituitary gland * initiates the development of follicles * increases estrogen during the uterine proliferative follicular phase
60
LH
* estrogen causes LH secretions to react * aids in maturity of follicles and ovulation * as well as corpus luteum development
61
What keeps the corpus luteum from degenerating if oocyte is fertilized? Resulting in the maintained levels of estrogen and progesterone, leading to NO menses?
Human chronic gandotropin (hCG)
62
hCG
Is secreted by the trophoblast which is transported in the blood to the ovary, causing corpus luteum to remain functioning •happens after implantation of trophoblast
