what leads into the rete testis

A

tubuli recti

sertoli cells

42
Q

what refers to the division of the spermatogonia to provide and continuous supply of cells that will eventually become primary spermatocyte

A

spermatocytogenesis

43
Q

what are the 2 divisions that reduce the chromosome number from diploid to haploid and makes spermatids?

A

meiosis

44
Q

what is it called when there is a transformation of spermatids to form spermatozoa

A

spermiogenesis

45
Q

wat is the nucleus of the sertoli cell like

A

pale, oval, and has indentations ( large nucleoulus)

46
Q

what junctions do sertoli cells form with each other

A

occluding junctions

47
Q

the occluding junctions of the sertoli cells forms what in the seminiferous tubule

A

divides its lumen into basal and adluminal compartment

48
Q

in side of the seminiferous tubule the spermatids are closer to the lumen or the basal layer?

A

the lumen

49
Q

where are spermatogonium located in the seminiferous tubule

A

at the basal layer,

they are the ones actually becoming the sperm

50
Q

what is the shape of a sertoli cell?

A

columnar

51
Q

what is actually pointing into the lumen of the seminiferous tubule?

A

the tails of the sperm

52
Q

what are the cells that are the outer layer of the seminiferous tubules and they are the next cells close to the interstitial cells

A

myoid cells

53
Q

what is the order of sperm cells from the bottom of the seminiferous tubules to the lumen?

A
  • spermatogonium
  • primary spermatocyte
  • secondary spermatocyte
