thanks a lot
Thank you
Thanks ❤❤❤🎉🎉🎉🎉
This explanation is probably the best I've seen on youtube and I've seen a lot ahah. It has been of extreme help. Thank you so much.
Now I can totally say I have an enormous problem with adductor muscles, both of the hallucis and plantar ossei, in my feet, because I cannot adduct anything in my toes... This is probably the cause of my foot support problems.
May I ask you what is an effective way to retrain muscles in these condition (a sort of total disconnection from the brain)?
Other than exercise, may be elettrostimoulous therapy useful? Or there are other kind of things?
Thank you in advance for your time.
Hi Marco!
It's hard to recommend anything without knowing the root cause of the problem. (Whether the problem is localized nerves or muscles, or whether its central origin). You'll need to be examined by a medical doctor. In medicine it's always recommended to try exercising (through a physiotherapists recommendations), and in some cases an electrostimulation can help toning the muscle to avoid atrophy. I see it's been 2 months since you've commented this: I hope you've found a solution for it from the time you wrote the comment =) All the best!
PS! Love your videos, you've got talent in playing pianos!
2:16 I’m confused. It’s an adduction, but it moves the toe more laterally from the body??? Is the foot itself the central point then?
Heya! The 2nd toe is considered central point =) So adduction is towards that centre toe, and abduction would be away from the centre toe. It's because if you look at your own foot while abducting the toes, you'll see that the 2nd toe is the only one not moving. So it's naturally considered the centre toe! Same with the hand and the 3rd digit.
@@TaimTalksMed Ah I see, thanks for the explanation!
How about peroneus tertius?
It's included in the anterior compartment of the leg

Pls I want physiology classes also😢 pls help me😢sir
@GUDGIRLfacts Hi! I've covered cardiac physiology with quizzes. They'll be released over a periode of time, but channel members can access all of them early (plus get access to quizzes) I'm also working on notes and quizzes for all the anatomy videos aswell😊
