1.2.2 Uterus, Vagina, and Fallopian Tube Flashcards
At what stage of development does the embryo implant?
Blastocyst
What are the PC?
Peg cells - non-ciliated, secretory, elongated nuclei
What occurs at day 1?
Identify the two types of epithelium?
What are the two divisions of the endometrium?
Stratum functionale (lost during menstruation)
Stratum basale
Where does fertilization occur?
In the ampulla of the uterine tube, allows time for the gamete develop prior to implantation
Identify the layers
Where is the regeneration zone?
Settled b/t the two layers of the endometrium
Identify the hormone type or cycle type.
Pituitary Hormones
Ovarian Hormones
Ovarian Cycle
Uterine/Menstrual Cycle
Which section of the uterine tube?
Ampulla
What phase?
Top: beginning of the proliferative phase
Bottom: Towards end of proliferative phase
Which section of uterine tube?
Intrauterine (intramural)
What days of the cycle is the proliferative phase?
Day 5-14
What are the two layers of muscle in the uterine tube?
Inner: Circular
Outer: Longitudinal
How does estrogen effect the ratio of ciliated to non-ciliated cells?
Increases the # of ciliated cells to increase the sweep into tube
What stage?
Menstrual stage
Identify the three layers
What this be?
A Vagineener
What is the main hormone of the proliferative phase? The secretory phase?
Proliferative: Estrogen
Secretory: Progesterone
Where are these glands?
Endocervix
When is the secretory phase? What is occuring?
Day 15-28
Which section of the uterine tube?
Isthmus
What is occuring during the proliferative phase?
Identify the four regions of the uterine tube
Compare the different stages of the secretory phase?
Early: highly coiled, basal vacuoles
Late: apical vacuoles contain glycogen-rich secretions
What are the three phases of the uterine cycle?
Menstrual phase, proliferative phase, secretory phase
What type of uterus?
Post-menopause
What layer?
Stratum functionale
Identify the regions of the uterus
Identify the uterine cycle phase?
Proliferative, Secretory, Menstrual
How can you differentiate b/t early and late proliferative?
Early: Straight glands
Late: Coiled glands and mitotic figures
Identify the sections of the uterine tube
Top Left: Intramural
Top Right: Isthmus
Bottom: Ampulla
Identify the three layers of the uterus
What is the name for a cyst found in the endocervix?
Nabothian Cyst
