What would the skeletal system be without muscles to move our bones. Muscles are an essential part of what makes us humans and in this lecture, I talk about the three types of muscle, and more importantly, how they work. How does muscle contraction happen at the cellular level? Why does the heart beat on its own? What is actin and myosin and what happens to our muscles in response to exercise? These are a few of the questions I answer in this lecture.
This is section 34.3 in the textbook Biology: The Dynamics of Life and is part of the chapter on Protection, Locomotion and Support. There are a few audio “glitches” in this video, but not too much to compromise your understanding of the material. Enjoy!

I am really pleased to find someone who speaks clearly and annotates well. I have actually used these lessons to teach me for my exams as my tutor is a little ajar from the group when she is teaching.
I cannot believe I am learning like this…..bring on reproductive system and nervous system.

Wow… you are a great teacher!!! I love this. Great way to review. Thank you ^_^
Your my NEW KHAN Academy!!!!! for BIOL!!!!! Thankssssss
im so cool..
I now understand much more thank you very much. Do you present Locomotion ( Muscles ) and Support ( Bone structure ) in two different topics or wasn’t the video long enough for both? thanks 🙂
I WILL PASS 1ST YEAR BIOL WITH THIS GUY
Yo yo… Awesome clip.
My dad had been a fatty. He enhanced his body from 284 lbs of pure fat into 214lbs of purely natural muscle mass. We thought it was extraordinary! I just registered personally as I’m going to boost my body shape. He made use of the Muscle Building Bible (Google it)…
