Conor McGregor's DEAD LEG Leads to Knockout at UFC 257 - Doctor Explains BRUTAL Leg Kicks!

Conor McGregor was knocked out by Dustin Poirier at UFC 257 after a flurry of brutal leg kicks caused McGregor's leg to go dead and weak. Poirier ultimately won by knockout to defeat McGregor, but the leg kicks were really the star of the show to help give Poirier the victory. In this video we'll review the leg kicks and explain the anatomy that makes them so effective in MMA!

EDIT 4:45, these are NOT dermatomes. Dermatomes come from the spinal nerve root levels, these are just the distributions from sensory peripheral nerves.

Will the UFC 257 performances be enough for Khabib to come out of retirement??
EDIT: 4:45, I mispoke in the moment, these are NOT dermatomes. Those are related to nerve root levels and not peripheral sensory nerves, which is what I am actually showing in the video. Just a difference of describing the cutaneous innervation from the sensory nerve (pictured) or the nerve root (L4, L5, etc)

Also, bonus points for those that caught my orange/green background colors

That must be why when you scratch the back of your knee, and then move it in a certain way, you get pins and needles around the top of the calf muscle.
