Male Reproductive #2 Flashcards
what are the two things that tubuli recti have to move sperm
microvilli
single flagellum
what is the epithelium of rete testis
simple cuboidal
what do the tubuli recti and the rete testis have in common
they both have flagellum
what is the collection of 10-20 tubules leading from the rete testis to the ductus epididymis
ductuli efferentes
what is the lining of the ductuli efferentes
simple
what has alternating clusters of non ciliates cuboidal and ciliated columnar cells
ductuli efferentes
what are the 3 important things about the cuboidal cells in the ductuli efferetns
- microvilli
- lysosomal granules
- reabsorb fluid from semen
what cells in the ductuli efferents aid in transporting the non motile spermatozoa toward the epididymis
ciliated columnar cells
what underlies the basil lamina surrounding the efferent ductules epithelium
a thin circular layer of smooth muscle
what are the 2 excretory genital ducts
- ductus epididymis
2. Ductus Deference
END part of the ampulla will be close to what
prostate
is ejaculatory duct inside or outside of the prostate
inside
what is the narrow highly coiled tubule that is 4-6 meters long
ductus epididymis
what surrounds ductus epididymis
CT with blood vessels
what is the lumen of the ductus epididymis lined with
pseudostratified columnar epithelium
what are the parts of the ductus epididymis
head
body
tail
what are the cells in the epithelium of the ductus epididymis
basal and principal cells
what are round and appear ot be undifferentiated and serve as precursors for columnar principal cells
basal cells
what is a name for lone irregular branching microvili
stereocilia
what has stereocilia on its luminal surface
principal cells
what specifically has pinocytic and coated vesicles in their apical portion supposedly for fluid resportion
principal cells
what secretes glycerophosphocholine a substance that can inhibit capacitation
principal cells
where does capacitation begin
epididymis
when is capacitation completed
when it reaches the oviduct
what is the process called when the sperm can fertilize an ovum
capacitation
the smooth muscle in circular layers under the basil lamina in the ductus epididymis does what
it undergoes peristaltic contraction that move the sperm toward vas deference
what is a straight tube with a thick muscular wall that goes from the ductus epididymis
vas deference
what is the epithelium of the ductus defernce
pseudostratified columnar ( stereocilia)
