b.During egg production, oogonia are produced throughout the lifetime of the female. T/F

c. The sperm in the middle of the seminiferous tubules are more mature than sperm in the outer layers. T/F

f. The increased amounts of estrogen secreted by a mature follicle trigger a burst of LH that triggers ovulation in the female reproductive system. T/F

Explanation / Answer

Answer:

a). False

Not all spermatogonia divide to produce spermatocytes; otherwise, the supply would run out. Instead, certain types of spermatogonia divide to produce copies of themselves, thereby ensuring a constant supply of gametogonia to fuel spermatogenesis.

b). False

Oogonia are not produced throughout the lifetime of the female. When a women gets menopause, she will not produce oogonia.

c). True

Mature spermatids are nearest the center of the seminiferous tubule, with their tailsextending into its lumen.

d). True

e).True

f). True

Estrogen provides negative feedback for FSH secretion and positive feedback for LH release by the anterior pitutary. The increasing amount of LH and decreasing FSH results in ovulation about midway through the cycle.
