W32/L5 Flashcards
What’s the name of the CT surrounding the testes?
Tunica albuginea
What is the internal organisation of the testes?
Septa that divide the testes into ~250 incomplete compartments.
What are the names of the tubes inside the testes?
Semniferous tubules
What is the order of structures that sperm pass through to get to the vas deferens?
- > Rete testes
- > Efferent ductules
- > Epididymis
What type of cells are in the tunica propria of the seminiferous tubules? (2)
Leydig cells
Myoid cells
Which cells are the support cells for spermatogenesis?
Sertoli cells
What’s the function of the myoid cells of the seminiferous tubules? (2)
Produce CT
Gentle, peristaltic contractions that sweep away the developed sperm
What’s the straight portion of the seminiferous tubules called?
Tubuli recti
What cells are in the tubuli recti?
Sertoli cells only
And then just simple cuboidal epithelium
Why are the rete testes interconnected?
For mixing
From which embryonic structure are the epididymis and vas deferens derived?
The mesonephric (Wolffian) duct
What cells line the rete testes?
Ciliated cuboidal
What cells line the epididymis?
Pseudostratified columnar epithelium with stereocilia
Where in the body do we find pseudostratified columnar epithelium?
Respiratory (cilliated)
Vas deferens (non-ciliated)
Epididymis (stereocilliated)
