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)

[@wasimluiz916]

osm ty for being with us .

[@AnginaFalengi]

Sperm is not equal to spermatozoa :)
Spermatozoa is the male gamete cell itself, while the sperm is cells + secretory products by accessory sex glands.
Good job though!

[@brendawang6784]

you are talking about semen

[@AnginaFalengi]

True. My mistake :)

[@MustafaKhan-jo1nq]

hm

[@its_aeious5277]

wow
really?why they say that it is equal to spermatozoa?how do they differ to eachother,kindly answer i'm confused

[@ahmedansari7982]

but in meiosis 1 cell divides into 4 cells. then how come it is divided into 2

[@gump155]

Congratulations for the video. There is a little mistake on 3:57, the primary spermatocyte already is undergoing meiosis.

[@safuraayman2618]

Spermatogonia multiply first by mitosis to increase in number and some of them differentiate into primary Spermatocytes that undergo meiosis

[@raidantarctica7551]

What's the chemical formula for it?

[@latishatisha1486]

Thank you so much!!

[@wrkin90044]

[@tylercrays7021]

I love the video, helping me in A&P

Hey can you please tell me at ehat age you reach puberty? I know it sounds a lil goofy but yeah if anybody knows

[@rithu4438]

its different for people but generally around your teens. Like 11-15. It also depends on the sex of the person. Males hit puberty at around 11 and females at around 12. I hope this helped xx
