Acrosomeis found in which part of spermatozoa

[@houriak848]

Sir u mentioned that the acrosome is placed in front of the nucleus but in so many books it's mentioned that it covers ant half of the nucleus I'm so confused pls correct if I'm wrong

[@MedicoVisual]

Please share the reference of book (Book name, edition and page number). I will have to take a look. Also please mention timestamp of the video for the context.

[@houriak848]

10.21 / book langmans 12th edition page 26

[@MedicoVisual]

In literature, I have found discrepancy related with this concept. Many of the books like Atlas of Histology with Functional and Clinical Correlations by Dongmei Cui (p.351) and Di Fiore's Atlas of Histology (11th ed., p.24) mentions that acrosome covers anterior tip/pole (not the complete one third, tip only) of the nucleus of spermatid.
On the other hand, you are correct, many textbooks clearly mention that anterior 2/3rd of nucleus is covered by acrosome.
Interestingly, in illustrations you will find all types of configuration. Some spermatids being shown in such way that whole of the nucleus is covered by acrosome. Other illustrations shows only anterior tip being covered by acrosome. And some show anterior 2/3rd of nucelus being covered by acrosome.
In my opinion, all types of configuration may exist in reality.

@@MedicoVisual thx for ur response it's really interesting

[@binalgangadia9094]

Sir i am confused between chorion leave and chorion can you explain this please?

[@MedicoVisual]

Please watch the lecture series on placenta. I have discussed the chorionic lavae in those lectures. If you are still confused after watching those lectures, feel free to reply back. I will try my best to explain.

[@binalgangadia9094]

@@MedicoVisual i had already watched that video but still I'm not able to understand that concept

[@MedicoVisual]

@@binalgangadia9094 Can you please elaborate that what point exactly you are confused about ?

[@binalgangadia9094]

@@MedicoVisual chorion is the most outer layer of embryo but after formation of placenta chorion leave is formed so chorion and chorion leave are same or not how it different from each other?

[@MedicoVisual]

@@binalgangadia9094 Think of it like this. Chorion is of two types:
1. The one with finger like projections has rough surface and is called chorionic frondosum
2. The other one without finger like projections has smooth surface is called chorionic lavae
Initially, the chorion (which is basically made up of extraembryonic somatic mesoderm and cytotrophoblastic layer) has finger like projections (also known as villi) on all the sides. At this stage, since only this type of chorion is present, so it is simply called chorion, but technically it is chorionic frondosum.
Later, at one side (luminal side), the villi are lost, perhaps due to decreased blood supply, so it becomes smooth and called chorionic lavae and the remaining part of chorion with those villi is called chorionic frondosum.
