"Testosterone is secreted by the seminiferous tubules"
found on p.265 in EK Biology Content Review Book
Is this right? I know spermatogenesis, production of sperm, occurs in the seminiferous tubules.
I know testosterone is synthesized in the testes and also in the adrenal cortex... right? (so within the testes maybe it is made in the seminiferous tubules, I am not sure exactly where tho)
EK Lec 5 Exam, Q107 on p.213
The follicle in its earliest stages is called a primordial follicle.
The primordial follicle most likely contains a:
B. diploid, primary oocyte
I know oocytes are arrested at birth in prophase I of meiosis I.
Females are born with primary oocytes (2n).
Just before ovulation, this primary oocyte completes meiosis I to become a haploid secondary oocyte .
So when this question says "primordial follicle" that means the follicle in its earliest stages before or at birth, so the answer is primary oocyte/diploid?
When does the "primordial follicle" develop?
A fully mature follicle would develop after ovulation.
I wasn't sure when primordial was, thought it was post-ovulation, so I picked haploid, secondary oocyte (C).
