Female Reproductive System- Histo Flashcards
Ovaries produce what?
Germ cells
T/F the ovaries have only endocrine functions?
False- both endocrine and exocrine
What two molecules are associated with endocrine function?
Estrogen
Progestogens
What is the job of estrogen?
promote growth and maturation of internal and external sex organs
Promote cyclic changes in uterine mucosa
Development of secondary sex characteristics
What do progestogens do?
prepare internal sex organs for pregnancy and (uterus) and prepare mammary glands for lactation
What is the exocrine function?
The ovaries produce and ovulate a secondary oocyte
T/F ovaries and testes have the same embryological origin?
True
Ovarian follicles are found within the ____ of the ovaries.
cortex
What is an ovarian follicle?
It is an oocyte surrounded by one or more layers of epithelial cells.
The size of the oocyte indicates what?
The developmental state of the oocyte
What are the three types of ovarian follicles?
- Primary follicles
- Growing follicles
- Mature or Graffian follicles
What is the process of the development of a germ cell to an oocyte?
Primordial germ cells–Oogonia–Primary oocyte
There are like 5 million ovarian follicles in the fetus. By puberty you only have like 300k but only about 400 are ovulated
okay
What are the cells called that surround the developing follicle?
Theca folliculi
Theca folliculi are made from which cells?
Stromal cells
Theca folliculi are what type of tissue?
Connective tissue
What are the two parts of the theca folliculi? What are their jobs?
Theca interna- in response to androgens, these secrete androgens (precursors to estrogen)
Theca externa- fibrous outer portion
What are the two cells of the corpus luteum?
Granulosa lutein cells
Theca lutein cells
Granulosa lutein cells produce what?
progesterone
Theca lutein cells continue to produce what?
estrogens
Where does fertilization take place?
In the fallopian tubes
What type of cells are found in the uterine tubes?
ciliated cells (help move oocyte towards uterus secretory cells (produces nutritive fluid covering epithelium)
T/F the fallopian tubes are muscular tubes?
truth
What are the three layers of the uterus?
Perimetrium- outer connective tissue
Myometrium- middle/thicketslayer, smooth muscle here
Endometrium- basal and functional layers- functional layer changes thickness
The vaginal canal has what type of epithelium?
non keratinized stratified squamous epithelium
The mammary glands are what?
tubuloalveolar apocrine sweat glands
