spermatogonium enter MITOSIS not meosis to become primary spermatocytes
The spermatogonium goes through mitosis when its on the basement membrane once it leaves the basement membrane it will start meiosis. The chromosomes in the spermatogonium replicate to form the Primary Spermatocyte.
@maryam b it's meiosis but meiosis 1
abdul bello no , spermatogonium B enters mitosis then it forms TWO primary spermatocytes , then the FIRST meiotic division occurs and it forms secondary spermatocyte then the SECOND meiotic division to forms four spermatids . One type B spermatogonium gives 8 spermatozoa,, but one primary spermatocyte gives us 4 spermatozoa.
Ya ur write firstly each spermatogonium goes into mitotic divison containing diploid number ...n make primary spermatocyte n now it goes into 1 meiotic division n make 2 equal haploid cell called secondary spermatocyte again tis go into 2 meiotic division to make 4 equal haploid spermatid.
Amazing! Thank you so much!
good video would recommend playing it to my uni students
Ty makes it easy to understand how sperm is made
Thank you so much❤
Don't miss guide. ..
Benfit vidio Thank you 💙
best video
awesome video! 🙊💯
This video is incorrect.
U have taken spermetogenesis but not mentining Y chromosome... all u are telling as like oogenesis (meiosis).. am not getting clarity to my view from this video
Masterpiece, thank you very very much!
Great video.
Wow
Human creation in Quran
وَلَقَدۡ خَلَقۡنَا ٱلۡإِنسَٰنَ مِن سُلَٰلَةٖ مِّن طِينٖ
We have created man from an extract of clay.
(Surah Al-Mu'minun, verse 12)
ثُمَّ جَعَلۡنَٰهُ نُطۡفَةٗ فِي قَرَارٖ مَّكِينٖ
Then We made him a sperm-drop in a firm resting place.
(Surah Al-Mu'minun, verse 13)
ثُمَّ خَلَقۡنَا ٱلنُّطۡفَةَ عَلَقَةٗ فَخَلَقۡنَا ٱلۡعَلَقَةَ مُضۡغَةٗ فَخَلَقۡنَا ٱلۡمُضۡغَةَ عِظَٰمٗا فَكَسَوۡنَا ٱلۡعِظَٰمَ لَحۡمٗا ثُمَّ أَنشَأۡنَٰهُ خَلۡقًا ءَاخَرَۚ فَتَبَارَكَ ٱللَّهُ أَحۡسَنُ ٱلۡخَٰلِقِينَ
Then We turned the sperm-drop into a clot, then We turned the clot into a fetus-lump, then We turned the fetus-lump into bones and We clothed the bones with flesh; thereafter We developed it into another creature. So glorious is Allah, the Best of the creators.
(Surah Al-Mu'minun, verse 14)
Thanks
