HD1 Histology Review (Male) Flashcards
what are the sertoli cells function? [2]
where are they located? [1]
what are nuclei like? [2]
what are the sertoli cells function? [1]
- *- form blood-testis barrier:** act as a bridge between interbular space and lume of tubule
- nourishment of spermatogenic cells
where are they located? [1]
- seminiferous tubules: span from the basement membrane to the lumen.
what are nuclei like? [2]
ovoid or triangular
label A & B of seminiferous tubule
A: sertoli cell
B: leydig cell
what is difference of nuclei between early spermatids and late spermatids? [1]
early: less condense
late: condensed nuclei - becomes elongated
where do you find leydig cells? [1]
what key feature do leydig cells normall have? [1]
where do you find leydig cells? [1]
outside of seminiferous tubules

at the end of each seminfierous tubule there is a transition to straight tubules (aka WHAT)? [1] tubuli recti
what is the histological change that occurs here?
changes to simple cuboidal epi
what do the tubules empty into? [1]
rete testis
what type of cells does the genital ducts become when it gets to the efferent ductules? [1]
what type of cells does the genital ducts become when it gets to the efferent ductules? [1]
pseudostratified columnar epi
looks saw toothed !
what type of cell is A? [1]
how can you tell? [1]
what is the function of A? [1]
what type of cell is A? [1]
leydig
how can you tell? [1]
clear cytoplasm
what is the function of A? [1]
The Leydig cells make and secrete testosterone, in response to lutenising hormone from the pituitary.
