Good question! I haven't seen any questions on the bone markings so there's a very low chance that they will be on TEAS. I'd say focus your time on all the bones including their locations and general functions, and skip bone markings. Hope this helps!😊
You are welcome! Glad to hear that the videos are helpful! Are you looking for where to get the ppt slides? The links for the slides are in the description section below each video. Let me know if you have trouble finding the links :-)
hello professor! for question 1, i knew the sternum is on the ventral side of our body but i didn’t know whether it was inferior or superior. can you explain that part to me? thank you!!
Sure, good question. It depends on what you compare sternum to. For instance, if you compare it to the head or the neck, sternum would be inferior because sternum is below the head or the neck. But if you compare it to, say, the abdominal area, pelvic area, coxal area, or any structures of the lower limbs, sternum would be superior because sternum is above all those body parts. Hope this answered your question. Let me know if you have further questions 🙂
Hi professor, for question 3 could you please elaborate on the the synthesis of vitamin D in relation to the skin and the kidney because doesn’t kidney also play a role in vitamin d synthesis and blood production? Thank you.
Sure. Good question. It's funny that you asked it because I recently started taking vitamin D supplement since I have vitamin D deficiency, lol. My husband told me to get more sun exposure but as you know, sunlight can be damaging to the skin and I don't want to look older than I already am, LOL. To make it simple, basically when UV-B hits the skin, 7-dehydrocholesterol (7-DHC) is converted to vitamin D3 (a vitamin D precursor) in the epidermis. Vitamin D3 enters the circulation and is hydroxylated (C-H is changed to C-OH; OH is a functional group called hydroxyl) to the main form of circulating vitamin D (25-hydroxyvitamin D3) by the liver. However, the 25-hydroxyvitamin D3 can be hydroxylated once more to a different but more potent form of vitamin D (1,25-dihydroxyvitamin D3) by an enzyme in the kidney, which is how kindey contributes to the production of vitamin D. I hope this helps. Let me know if you have additional questions!
I found a typo in my previous reply and fixed it yesterday. I also added a brief description of what hydroxylation is to the original reply. Hopefully you see the revised response instead of the first first response. Also I just realized that I did not answer the part about the kideny and blood production. Yes, the kidney is involved in regulating blood product by secreting a hormone called erythropoietin. Erythropoietin stimulates the production of red blood cells in bone marrow (RBCs are produced in the red bone marrow). Say you travel from a costal city (low elevation) to mountains in Colorado (high elevation). In response to the lower oxygen level (thinner air), the kidney will secrete more erythropoietin to ramp up RBC production so that more oxygen can be delivered to meet the body's oxygen demand.
OMG YOU TAUGHT ME AT CPCC
Haha, that's great! Yeah, I taught many sections of A&P and general bio. Glad you found me! ☺️
Should we know all the bones and also the specific parts of each bone? Or just knowing the general bone is enough ? Thank you

Thank you for taking the time to make these videos. I hope more people find these great videos!
Thank you! I appreciate it! I hope these videos can help more people too! Hope your studying is going well!
Thank you for the videos! However, does anyone know if these were we can get these powerpoint!!
Please and thank you!

@@professoryu5571 Hello professor, thank you so much for the explanation it helped me to clear up the questions I had.
@@Fluffy_cloud201 Great! Don't hesitate to let me know if you have any other questions!
