Hey, sir your videos are very helpful have you made video on ogenesis?

[@MedicoVisual]

Yes. ruclips.net/video/UYdh5gmirBo/видео.html

[@hawkdevil1712]

sir i have question does sperm proxiaml centriole helps secondary oocyte in their metaphse 2 as secondary oocyte are arrested in metaphase 2 and after the fusion of sperm with secondary oocyte it completes it's metaphase . so does sperm centriole helps in this .

[@MedicoVisual]

I have never heard of any role of centriole of sperm in resumption of metaphase of oocyte. If you have any reference that says so, please share. I will have a look.

[@fuseboxmusic4544]

Sir how 9+0 arrangement of microtubules becomes 9+2, centriole do not have any microtubules in central part?

[@MedicoVisual]

Yes, that's correct. Centrioles don't have central microtubules.

[@fuseboxmusic4544]

In microtubule originating complexes if the centriole is a "9+0" structure, then how does it give rise to cilia or flagella having a "9+2" structure?

[@MedicoVisual]

@@fuseboxmusic4544 Some tubilin proteins arrange in the center to create the two central microtubules. I don't know the detailed mechanism though. I will dive deeper into it when I will create a lecture specifically on cilia and flagellum.

[@MedicoVisual]

Great questions by the way.
