NEET Question

|
Option (b) because the process of oogenesis in human female starts at the foetal stage not from puberty.
|
|
The process of formation of a mature female gamete is called oogenesis. Unlike sperm formation that starts at pubarty egg formation begins before birth. Primordial germ cells complete the proilferative stage or oogenesis in the early embryonal stage when million of gamete mother cells (oogonia) are formed within each faetal ovary, no more oogonia are formed and added after birth.
|
|
Wrong statement is b
because during ovulation immature ovum is released
it become secondary oocyte (mature ovum after entry of sperm )
because during ovulation immature ovum is released
it become secondary oocyte (mature ovum after entry of sperm )
|
|
This process starts in human male oogenesis is start from foetal stage not from at puberty.
|
|
Secondary oocyte is released during MC that is imature or non-functional . after entry of sperm mature ova formed that is fictional ova
|
|
Correct answer is option.b. Oogonial cells start to proliferate and give rise to functional ova in regular cycle puberty onwards
|
|
During menstural cycle at 14th day estrogen level is high trigger ovum to release ova.
|
|
My insta id razeen_abdulrahim and option is b.....oogenedis start from embro stage..not from puberty stage
|
|
Wrong statement is option 'B'.It is because immature ovum is released in secondary oocyte stage.
|
|
B is right choice. because Germ cells after 1 time mitosis grown into oogonia and oogonia after 2 times meiosis( I and II) converted into a function ovum cell and degenerative polar body and .these all change occur at foetal stage not at puberty
|
|
Option B because oogonial cells proliferate through mitosis during 9 to 22nd week of embryonic development but not in puberty
|
|
Option B : Oogonial cells start to proliferate and give rise to functional ova in regular cycle puberty onwards.
|
|
|
Answer is b bcz primordial germ cell complete proliferative stage or oogenesis during embryonal
stage not on puberty
stage not on puberty
|
|
Oogonial cells do not proliferate. they are suspended in meiotic-2 state. They only form 1 primary oocyte. option B would be the answer.
|
|
Functional ova is released only after the fertilization not in regular menstrual cycle
|
|
The process of formation of mature female gamete is called oogenesis unlyk sperm formation that starts at puberty of egg formation begins before birth. Primordial germ cells complete the proliferative stage or oogenesis in the embryonal state when million of gamete mother cells r formed within each featal ovary no more oogonia r formed and added after birth. That's y correct option is (B)
|
|
Because M-2 is not completed until or unless sperm doo not enter the ovum cytoplasm
|
|
Because puberty ke aane ke pahle hi oogonial cells ka proliferation start ho jata h.. even meiosis 1st tak pahuch jata h.
|
|
Wrong statement is (b) because during ovulation immature ova is released and it become mature after the entry of sperm
|
|
Oogonial cells start to proliferate during feotal stage....that part is incorrect....but ova is produced at time of puberty only...so bcoz half part is incorrect that option is worg
|
|
The process of formation of a mature female gamete is called oogenesis. unlike sperm formation that starts at puberty. egg formation begins before but promote the real germ cells complete the proliferate stage or oogenesis. in the early embryonic stage when billion of of gamut who gonio are formed within each faetal ovary. no more oogonia are formed and added after birth.
|
|
In case of female the process of ogenesis means ,formation of ovum, in its birth time is constant. ovum contenuesly releases but mature ovum releases at puberty
|
|
Option b is the wrong statement because at 14th day estrogen triggers the ovum to release ova.
|
|
Oogonial cells start to proliferate and give rise to functional ova during embryonic stage
|
|
The process of ooge esis start during the embryonic development when million of oogonia formed within each foetal ovary no more oogonia is added after birth so option b
|
|
The process proliferation of oogonial cells starts in the female during its embryonic stage onwards and the maturation of spermatocytes in males takes place after puberty...don't get confused
|
|
Answer -B is wrong statement because ovulation is female egg mature stage and pubility is reproductive stage
|
|
Oogonial cells are primordial cells in human females which divide and form primary oocyte(2n) which further divide into secondary oocyte (n) which is divided by meiosis.
|
|
Sec. Oocyte comes in the form of MC
if sec. oocyte is fertiliz to sprem then ova is ready
if sec. oocyte is fertiliz to sprem then ova is ready
|
|
|
'B'- Oogenesis is initiated during the embryonic development stage when a couple of million gamete mother cells(Oogonia) are formed within each foetal ovary (about 3rd month of foetal ovary), no more Oogonia are formed and added after birth.
|
|
There are many ova in female baby since from birth. It only mature at time of puberty
|
|
(B) option is bcz ova is functional when sperm is come in contact with sperm
|
|
Oogonial cells start to proliferate and give rise to functional ova in regular cycle puberty onwards
|
|
B,, bcoz Oogonial cells start to proliferate during intra Embryonic life of a female baby
|
|
B is the wrong statement
The gamete formation starts in female when the female is just an embryo, not from puberty onwards.No more oogonia are formed and added after birth.
ovulatory phase is followed by luteal phase where graffian follicle is transformed into corpus luteum which secretes progesterone.
sperms released from seminiferous tubules is poorly motile/non-motile.It only get vigourous motile power when it is temporarily stored in epididymis.
only fully matured ovum get released from ovary. ovum released from ovary in the form of secondary oocyte.ovam getvits maturity only when follicular development occurs around primary oocyte.The process of release of secondary oiche from ovary is termed as ovulation.so high levrl of estrogen trigger the ovulatory surge.

|
Post-ovulatory phase is also known as the luteal phase. During this period, the follicle proper folds inward on itself and transform into the corpus luteum which is a steroidogenic cluster of cells that produces estrogen and progesterone. The action of progesterone increases the basal body temperature.Â
So, the correct answer is "Progesterone level is high during the post-ovulatory phase of the menstrual cycle."
So, the correct answer is "Progesterone level is high during the post-ovulatory phase of the menstrual cycle."
|
|
This is not possible because at the menstrual cycle each oogonial cells get ruptured according to their turnover until it's fertilized
|
|
Unlike sperm formation, that starts at puberty ,egg formation begins before birth.Primordial germ cells complete the proliferative stage or oogenesis in the early embryonal stage when million of gamete mother cells (oogonia) are formed within each fetal ovary ,no more oogonia are formed or added after birth..
|
|
Oogenesis is initiated during the embryonic development stage when a couple of million gamete mother cells (oogonia) are formed within each fetal ovary (about third month of foetal ovary), no more oogonia are formed and added after birth.
|
|
Option b is correct because in human female every month ova is released .if it is not fertilized it may degenerates .at the foetal stage ova is not released in female .
|
|
Answer is b because ogonial cells have formed the oocytes much before puberty
|
|
B is the correct option as oogenesis starts at foetal stage of the human being
