What are areas in the uterine tube considered prox/distal to?
The uterus, not the ovary
What is the funnel-shaped, distal end of the uterine tube?
The Infundibulum
What are the fingerlike projections that extend from the infundibulum?
What is the distal 2/3 of the oviduct?
The Ampulla
What type of epithelium lines the lumen of the ampulla?
Ciliated and nonciliated Simple Columnar cells
What is the proximal 1/3 of the oviduct?
The isthmus
What is the segment that passes through the uterine wall?
The Intramural part
Where are mucosal folds in the oviduct most abundant?
In the infundibulum and ampulla
What hormone promotes ciliogenesis and mitosis of the simple columnar epithelium lining the oviduct?
What hormone stimulates secretory activity and smooth muscle contraction in the oviduct?
What regulates contraction of the smooth muscle in the muscularis of the oviduct?
Progesterone and estrogen
What are the layers of smooth muscle that surround the oviduct?
-Inner circular
-Outer longitudinal
What is the layer that covers the entire uterus?
Perimetrium - a serosa
What is the name for the serosa?
Broad ligament
What is the myometrium?
The thick longitudinal and circular layers of SM that lie just under the serosa of the uterus
What is the smooth muscle cell length dependent on?
Estrogen - it gros 10X thicker during pregnancy
What hormones quiet uterine smooth muscle?
What hormone stimulates uterine smooth muscle?
What layer of the uterine wall is just under the muscle layer?
The endometrium consists of what 2 zones? How much is each?
-Functional zone - outer 2/3
-Basal zone - inner 1/3
Which zone undergoes menstruation?
Functional zone
What type of blood supplies are in the Functional zone? Basal?
Functional: spiral only
Basal: spiral and straight
What type of arteries are sensitive to changes in estrogen?
What happens to the spiral arteries during menstruation?
They constrict and cause blanching of the endometrial lining as it is sloughed off.
What type of epithelium lines the exocervix?
Stratified squamous non-cornified
What does the stratified squamous epithelium change to at the cervical canal?
Simple columnar
What is the zone of the cervix that contains simple columnar epithelium?
What is the region connecting the exocervix and endocervix called?
The transitional region
What is the clinical significance of the transitional region?
It is where cervical cancer most frequently develops
What type of epithelium lines the wide branched cervical glands?
Simple columnar
What is the lumenal surface of the uterine epithelium in the functional region like during the menstrual phase?
What is the lumenal surface of the uterine epithelium in the functional region like during the proliferative and secretory phases?
What are the glands of the functional zone in the uterus like during the proliferative phase?
What days does the Proliferative phase consist of?
What type of epithelium lines the glands in the uterus?
Simple columnar
What surface specializations can be seen on the glandular epithelial cells?
Cilia and microvilli
What shape are the endometrial glands during the:
-Proliferative phase
-Secretory phase
Prolif: circular
Secretory: sawtooth
What days does the Secretory phase consist of?
What shape are the uterine glands during the secretory phase?
What key event is occurring within the ovarian cycle as the uterus is entering the secretory phase?
What is the secretory phase intended to do?
Prepare the uterus for implantation
How does the uterus prepare for implantation?
By becoming edematous and full of carbohydrate and glycogen
If implantation does not occur what happens at the end of the secretory phase?
The spiral arteries constrict and the ischemic lining is sloughed off.
What is the endometrium controlled by during the late secretory phase?
Estrogen and progesterone
What would you expect to see in the pregnant uterus?
More smooth muscle in the myometrium.
What type of intercellular specializations would you expect smooth muscle cells to possess?
Gap junctions
Which pituitary hormone are the smooth muscle cells in the pregnant uterus a target for?
Is the cervical mucosa sloughed during menstruation?
What type of epithelium lines the exocervix again?
Stratified squamous nonkeratinized (wet) epithelium
What is the wall of the exocervix like?
Mainly CT, more than SM
What do the cervical glands produce?
What is the consistincy of cervical mucus under estrogen dominance? Why?
Watery and abundant - because Estrogen dominates just before ovulation, and it aids in sperm transport
What is the consistency of cervical mucus under progesterone dominance? Why?
Thick and sparse - because Progesterone dominates during when implantation would occur, and you DON'T want more than one sperm.
What type of epithelium lines the vagina?
Stratified squamous nonkeratinized
What is the epithelium of the vagina like during estrogen dominance?
Thick, keratinized and cells are full of glycogen
What is the vaginal epithelium like during progesterone dominance?
Thin and nonkeratinized
What are the 4 main parts to the external genitalia?
1. Clitoris
2. Labia minora
3. Labia majora
4. Vestibule
What part contains hair?
Only the external surface of the labia majora
Which part contains fat?
The labia majora
What glands are in the vestibule?
Bartholin's glands
