Front (Question)

Name the structure within the testes which produces the male gamete

Back (Answer)

Seminiferous tubules

Front (Question)

Name the structure within the testes which produces testosterone

Back (Answer)

Interstitial cells

Front (Question)

Describe the function of the prostate gland and seminal vesicles

Back (Answer)

Secrete fluids that maintain the mobility and viability of the sperm

Front (Question)

Name the part of the brain which secretes a releaser hormone

Back (Answer)

Hypothalamus

Front (Question)

Describe the role of the releaser hormone

Back (Answer)

Stimulates pituitary gland to produce hormones that trigger puberty

Front (Question)

Name the part of the brain which secretes FSH, ICSH and LH

Back (Answer)

Pituitary gland

Front (Question)

Describe the effect of FSH and ICSH on the testes

Back (Answer)

FSH acts on semeinferous tuboulues, it promotes sperm production, and ICSH acts on interstitial cells, its stimulates testosterone production.

Front (Question)

Describe the effects of testosterone

Back (Answer)

Stimulates sperm production and activates prostate gland and seminal vesicles.

Front (Question)

Name the hormones which are inhibited by high levels of testosterone

Back (Answer)

FSH and ICSH.

#10

Front (Question)

Explain how levels of testosterone are controlled by negative feedback

Back (Answer)

As testosterone levels increase it inhibits secretion of FSH and ICSH This causes the levels of FSH and ICSH to decrease reducing the volume of testosterone production. As testosterone levels decrease, inhibitory effect is switched off and levels of FSH and ICSH increase This causes an increase in testosterone level

#11

Front (Question)

Name the structure where ova mature

Back (Answer)

Follicle

#12

Front (Question)

Describe the role of the follicle

Back (Answer)

Protectsthe developing ovum and secretes hormones (oestrogen)

#13

#16

Front (Question)

Name the first phase of the menstrual cycle

Back (Answer)

Follicular Phase

#17

Front (Question)

Describe the effect of FSH on the ovary

Back (Answer)

Stimulates follicle development and oestrogen production.

#18

Front (Question)

Name the hormone produced by the follicle

Back (Answer)

Oestrogen.

#19

Front (Question)

Describe the effects of oestrogen

Back (Answer)

stimulates proliferation of the endometruim , preparing it for implantation. it also affects the consistency of cervial mucus, becoming thin and watery

#20

Front (Question)

Explain why the consistency of cervical mucus changes during the follicular phase

Back (Answer)

to make it easily penetrable by sperm.

#21

Front (Question)

Describe what happens to the LH levels following peak levels of oestrogen

Back (Answer)

There is a surge in LH.causing ovulation

#22

Front (Question)

Name the event which occurs following a surge in LH

Back (Answer)

Ovulation

#23

Front (Question)

Describe the process of ovulation

Back (Answer)

Release of matureovum from a follicle, usually occurs in mid-point of the cycle.

#24
