Question

1.What role do the hormones FSH and LH play in male sexual development

2.Describe how a primordial follicle develops into a Graffian follicle and ovulates, and then what happens to the follicle?

3.Explain how high blood pressure can damage your kidneys

Answer 1

ANSWER -

FSH and LH are the two reproductive hormones which are secreted from the anterior pituatary when the gonadotrophin hormone is released by the hypothalamus and they helps in the formation of the reproductive content.

FSH called as follicle stimulating hormone is general helps in the formation and maturation of the follicle and LH is called as leutizing hormone which helps in or causes the ovulation.

THESE hormones also have role in male sexual development and this is:

LH use to stimulate the production of the testesterone from the leydig cells also called as interstitial cells of the testis.

FSH use to stimulate the testicular growth and also increases the production of the androzen binding site and this site is very important for the spermatogenesis and also helps sertoli cells to work efficiently and so these both hormones also play a major role in sexual development.

ANSWER 2

The process of the formation of the reproductive cells starts from the birth , at birth primordial cells are multiplied during the fetal development .

During the stage of the birth apporximately 4 lakhs primordial follicles are developed which do carry primary oocyte,

And till the age of sexual maturity these primary oocytes do not divide and at the age of sexual maturty two hormobes FSH and LH are released and in each ovarian cycle about 20 primodial are activated and they started to mature.

and in which one matures and rest goes like this only.

when these are activateed then some these follicles are developed and matured by the FSH and then first meotic divison occurs and in this primary follicle is converted into the secondary follicle and then after second meotic division occurs called as the grafian follicle which do also have a secondary follicle,'

And the follicle remains in this stage only till fertization occurs ,

Now due to the effects of the LH leutinizing hormone called LH makes the process of ovulation in the mid of the cycle then the ovum gets released from the grafian folllicle starts converting in the corpus letum.

Corpus leuteum is the remannat of the grafian folilce and they plays a major role in pregnancy if the fertilization occurs , it secretes the progesterone and hormones to be secreted fast and also in maintainence of the endometrium for the new conception.

If the fertilization doesnt ocurs into the content and it is converted into a small whitish substance called corpus albicans is seen and they it to regenerate.

THIS IS THE WHOLE CYCLE OF THE OOGENESIS , THE FORMATION OF THE OVUM AND THE STAGES OF FOLLICLE AND CORPUS LEUTEUM.

Answer (3)

High blood pressure directly affect the kidney or cause blood pressure because the kidney and heart are related

through each other by renin angiotensin system which maintaisn the blood pressure in body.

And the reason is the nephrons of the kidney take there nutrient in the form of blood through the small capillaries or vessels present near the nephrons , when for long time blood pressure remains high then these arteries starts getting weak and hardened too , so when these arteries found to cause problem and dont able to provide the oxygen for the kidney and so kidneys get damaged,
