Repro!!!

It's hard to believe that you guys are done with all the material for the semester! Good job getting through it all. We hope you have enjoyed the class and learned a lot along the way. Looking through Repro/Urinary, there are just a couple of things I want to make sure you guys know:

-KNOW spermatogenesis and oogenesis (what each cell type looks like. Check out the pics below for help with this.

The manual does a good job explaining all of the cell types except for spermatids. Notice how they can either look like darker secondary spermatocytes OR like spermatazoa without the developed tail?? We wouldn't ever ask you to differentiate between spermatazoa and spermatids on a U-Find because you can't see the tails really... Understanding how each cell type corresponds with meiosis helps too (e.g. why the primary spermatocyte is so big/chromatin is so visible).

-Here is a cool electron micrography with the different spermatogenic cells labeled. Here is a section of an immature teste. See the diff in the epithelium?? No spermatogenesis... Finally, here is a teste slide, can you identify the epididymus, seminiferous tubules, and all of the spermatogenic cell types?

Pretty straightforward. The manual does a good job differentiating the different follicle types. 

Look first for the primary spermatocytes - they're gonna be the largest cells (#3) - now can you see the spermatagonia (#2)?

Immature testis - notice how there are no spermatids or spermatazoa?

Ovaries:

Remember - ANYTHING with more than 1 layer of granulosa cells around it is a secondary follicle

Make sure you know all the parts of a graafian follicle

What is the red arrow pointing to??? (corona radiata)

-Fertilization occurs in the....... OVIDUCT!!! Remember that....

Don't forget to review Urinary - let me know if you have any questions!

Reproductive Review Sheet

Key: Know the anatomical and histological names (including modifications) for the following bolded structures; assume that you will be required to find the structures indicated by * on your own slides.

***This list is not guaranteed to be exhaustive, and only includes terms from this unit. While we will not focus on quiz information from previous weeks, knowledge of previous material may be useful***

Focus on reproductive histology, but keep in mind that this unit integrates information from previous topics. Anything in the lab manual for this unit is fair game.
