Great work
Thanks a lot, Ur work is very helpful🙏
Just a correction in this video
Orbital part of orbicularis oculi is responsible for forceful closure of eyelids
And
Palpebral part is responsible for gentle closure of eyelids
In the video, it was mentioned that both these parts are responsible for forceful closure which is not correct.
