In order to fully understand the mechanism of muscle contraction, we need to consider the structure of muscle fibres and how the proteins are arranged within them.
There are three parts in this video: 1.) Muscle fibre arrangement; 2.) Sacromere structure; 3.) Structures of actin and myosin.
Each part ends with a quick mini-summary, then a final summary of everything near the end of the video.

for everyone asking, yes it is sarco ( Greek for flesh ) not sacro. SARCO is the correct term, the notes are very good though

Love the video! Very helpful. But isn't it a saRComere/ saRCoplasm etc & not a saCRomere?

Isn’t it sarcolemma and sarcomere? That’s what it says in my A-Level Biology textbook.

Yes you're right! I made a really stupid mistake there... Might remake this whole thing at some point!

wait why is it called a sacromere, in my book it's called a sarcomere?

Yes my bad, somehow in my head sacromere spells better, but then I know it should be sarcomere... Sorry about that and well spotted! :D Thanks for watching!
