Theca interna

A

Layer that forms around a developing oocyte. Contains blood vessels, smooth ER (steroid hormones), lipid droplets, and mitochondria. Appears in a secondary follicle.

Q

Corona radiata

A

Tightly packed layer of granulosa cells that surround an oocyte. Appears within a Graafian follicle and is present upon release of the secondary oocyte into the oviduct

Q

Atretic follicle

A

Follicle in the process of dying. These follicles will not be used for fertilization. It contains apoptotic oocytes.

Q

Corpus luteum

A

Formed after the oocyte is released into the oviduct. Maintains high levels of progesterone until the placenta fully forms

16
Q

Ectopic pregnancy

A

Occurs occasionally when the egg is implanted into a wall in the oviduct. The egg doesn’t get enough nutrients so it starts to break down.

17
Q

Layers of the oviduct

A

Mucosa -> Muscularis -> Serosa

18
Q

Epithelial cells of the oviduct

A

Secretory and ciliated cells

19
Q

Corpus

A

Site of implantation in the uterus

20
Q

Cervix

A

Opening of the uterus into the vagina

21
Q

Layers of the uterus

A

Endometrium -> Myometrium -> Perimetrium

22
Q

Basalis

A

Small layer of the endometrium that remains beyond menstruation

23
Q

Uterine glands (proliferative phase)

A

Located in the endometrium. Simple tubular in the first half of the cycle and coiled in the second half.

24
Q

Cervix

A

Opening of the uterus into the vagina. Contains 2 different layers of epithelium. Simple columnar cells on the inside that secretes fluid for protection from bacteria. Stratified squamous non-keratinized layer around the outside.

25
Q

Progesterone

A

Released by the corpus luteum to Inhibit ovulation. Reduces ciliary motion and increases cervical viscosity

26
Q

Human chorionic gonadotropin (hCG)

A

Enters the maternal circulation upon implantation. It “rescues” the corpus luteum and prevents it from breaking down.

27
Q

Placenta

A

When fully formed, it takes over the production of maternal hormones needed to maintain pregnancy

28
Q

Layers of the vagina

A

Vaginal mucosa -> muscularis -> serosa

29
Q

Vaginal mucosa

A

Stratified, squamous non-keratinized epithelium and underlying lamina propria that undergoes cyclic changes with menstrual cycle

30
Q

Vaginal muscularis

A

smooth muscle layer beneath the lamina propria. Muscle loosely arranged in circular and longitudinal muscle layers

31
Q

Vaginal serosa

A

Outer layer of vagina that consists of dense connective tissue and elastic fibers

32
Q

Skene glands

A

Secrete lubricating fluid within the vagina

33
Q

Bartholin’s gland

A

Secretes mucous for lubrication within the vagina

34
Q

Labia majora

A

abundance of sebaceous and sweat glands, stratified squamous keratinized tissue

35
Q

Labia minora

A

Doesn’t have as many glands as the majora, stratified squamous keratinized tissue

36
Q

Primordial follicle

A

Oocyte surrounded by a layer of follicular cells within the ovary

37
Q

Corpus albicans

A

Formed from the corpus luteum if fertilization does not occur. Filled with fibrous tissue

38
Q

Urethra

A

Pseudostratified columnar
