Bones: Structure and Types

[@kittymeowski]

Well Professor Dave, you've gotten me through four chemistry classes and now we're on to anatomy.

You prolly dont give a shit but does someone know of a way to log back into an instagram account..? I stupidly lost my login password. I would appreciate any assistance you can offer me

[@corycade9041]

@Benton Neil thanks so much for your reply. I found the site through google and Im in the hacking process atm. Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.

[@corycade9041]

@Benton Neil it did the trick and I actually got access to my account again. I'm so happy! Thanks so much you saved my ass :D

[@bentonneil7416]

@Cory Cade No problem xD

I started watching your videos just yesterday, and although I have just earned my B.S. degree in Exercise Science, these videos are exactly what I need to stay engaged in my field. Whether you see this or not, thank you, Professor Dave. It is hard for me to enjoy studying materials over because of how boring it is, but I love watching these videos. It feels a lot better knowing that this material is not insanely hard to learn and remember when taught the way that is best for me. You are making a huge difference in peoples' lives including mine.

I think I understand the video but the problem is how I can remember all those details mentioned in this video. Do I have to learn by heart all of them during the study? I am just preparing for my study program in kinesiology so a bit worried about this. Thanks!

[@colinholloway8076]

So much information. I have studied this actually it is hard to take in when you get it all in one big lump like this but useful. Just one thing . You need to look at the science behind tensegrity structures. We are not held together by bone. We are not a compression structure. The muscles and more importantly the fascia is tensioned and in about four dimensions , maybe more to hold the skeleton up. The tension comes from the outside in, not the other way around. Apart from that lots of detailed information that appears accurate to me. Thanks.

Is the rate of formation of bone in the periosteum faster? And does it push all these formed osteons inwards ending up in medullary cavity?

[@Unknown-hw7bd]

Vry nyc video .. explained bone in such a easy way .. thnku ♥️

[@sthakkartaniya]

Thank you so much for this👌👍🙌💛 I still have one doubt and request if you can solve my query. It is written that osteoblast forms new bone but only the osteogenic cells are the only cell that can divide. But if osteoblast can form new bone means it will divide than only it can form new bone so than Y do we say that only osteogenic cells are the only cells that divide?? I would be waiting to hear from you. Sincerely, Taniya

[@worldaround6520]

Thank you for the video, sir. The ends of long bones consist of spongy, or cancellous, bone, which is adapted to absorb shock and prevent damage to the bone's core. The extremities of bones need to be spongy because shockwaves typically come from external forces, not from within the bone. When we cancel something, we often make a cross mark ❌, and similarly, cancellous bone has a crisscross structure of bony material. This structure creates significant empty space, making the bone spongy and allowing it to house red bone marrow. However, I’m uncertain why specifically red marrow, rather than yellow marrow, is found here. If anyone has insights on this, please enlighten me.
