Reproductive Tract Histology Flashcards
Where in the fallopian tube does fertilisation occur?
In the ampulla
At what stage of the menstrual cycle are the breast at their largest?
During the luteul phase
What is the surface layer of the ovary?
Simple stratified or cuboidal epithelium
How does the endometrium change in preparation for implantation?
Glands increase in size and start secreting mucoid with glycogen
Epithelial, stromal and vascular cells proliferate
What do the follicular cells of the primordial oocytes become in the primary oocytes?
Granulosa cells of the stratum granulosum
What is contained in the prostatic secretion?
Acid phosphatase, fibrolysin and coagulating factors
What is in the inner medulla of the ovaries?
Loose connective tissue
Blood vessels
What are TDLUs?
Terminal duct lobular units - made up of interlobular collecting ducts and terminal ductules or acini
In which part of the penis does the urethra run?
Corpus spongiosum
What is the epitheliun of the ectocervix?
Stratified squamous epithelium
Non-glandular
How is the vagina lubricated?
By cervical glands
Or glands in the vestibule
Why are Leydig active for the first 5 months of fetal life?
To produce testosterone required for sex determination
Describe the histological structure of the clitorus
Bilateral cavernous tissue surrounded by tunica albuginea
At what follicular stage does the antrum arise?
The secondary follicle
Where does the tunica albuginea lie in the ovaries?
Between the epithelium and stromal connective tissue
What is the name of the structure that connects the seminiferous tubules to the epididymis?
Rete testis
Which layer of the endometrium is sloughed off during menses?
The functional layer
What cells line the lumen of the efferent ductules and epididymis?
Pseudostratified columnar epithelium
What is the function of the prostatic secretion?
Causes the ejaculate to clot (immobilising it) then fibrolysin dissolves the clot and frees the sperm
What can occur if a oocyte is fertilised outside of the fallopian tube?
Ectopic pregnancy
What happens to sperm and semen in the epididymis?
They mature
They are decapacitated to prevent them damaging the wall
Fluid and debris is absorbed
What is cortical stroma made up of?
Highly cellular connective tissue
Scattered smooth muscle cells
What lines the internal layer of the fallopian tube?
A serosa that is mesothelium plus a thin layer of connective tissue
What prostatic zone surrounds the prostatic urethra?
The transitional zone
