AS 351 - female microanatomy

what are the types of epithelial tissue?

columnar, cuboidal, squamous

columnar epithelium

height of cell exceeds the width and depth

cuboidal epithelium

width, depth, and height are approximately the same

squamous epithelium

width and depth of the cell is greater than the height

what cells are found in the ovary?

simple cuboidal epithelium

what cells are found in the oviduct?

- simple columnar ciliated epithelium

oviduct: infundibulum

- all ciliated cells

- thin muscle layer

- simple columnar

oviduct: ampulla

- some ciliated cells, some are not

- thicker muscle layer

- simple columnar

oviduct: isthmus

- non ciliated cells

- thickest

- closest to uterus

- simple columnar

what cells are found in the uterus?

- simple columnar epithelium

- some ciliated, some are not (secretory)

uterus: endometrium

simple columnar epithelium

uterus: perimetrium

simple squamous epithelium

uterus: myometrium

- circular, longitudinal

uterus: endometrial glands

simple tubular glands lined by columnar epithelium

what cells are found in the cervix?

simple columnar epithelium

cervix: mucosa

simple columnar epithelium, some are ciliated and nonsecretory

the cervix has _______________ cells

goblet secretory

what cells are found in the caudal vagina?

stratified squamous epithelium

what cells are found in the cranial vagina?

simple columnar epithelium (ciliated and non ciliated)

what cells are found in the fornix vagina?

simple columnar epithelium

what cells are found in the primordial stage of the follicle?

simple squamous epithelium

what cells are found in the primary stage of the follice?

simple cuboidal epithelium

what follicle is this and where does it come from?

primordial and primary follicles; comes from the ovary

what follicle is this and where does it come from?

secondary follicles; comes from ovary

what follicle is this and where does it come from?

tertiary/antral/graafian follicle; comes from ovary

what are granulosa cells?

endocrine cells that are receptors for FSH and produce estrogens and inhibin

what is the basal lamina (basement membrane)?

separates theca cells from granulosa cells

what are theca interna cells?

endocrine cells that are receptors for LH and produce androgens

what are theca externa cells?

cells and connective tissue layer that supports the follicle

what does the image represent?

the corpus luteum (CL) in the ovary

where are small and large luteal cells located?

in the corpus luteum

what structure is this? and where is it located?

infundibulum; located in the oviduct

what is the cumulus oophorus?

a cluster of cells that surround the oocyte both in the ovarian follicle and after ovulation; surrounds ovum to aid in pick up by fimbria

what structure does this represent? where is it located?

ampulla; located in the oviduct

what cells are in the ampulla?

• simple columnar epithelium; ciliated and non ciliated

• intercalary (peg) cells

what structure is this?

isthmus

what cells are in the isthmus?
