How do Muscles Contract? Sliding Filament Theory | Corporis

Your muscles contract thanks to something called the sliding filament model, sometimes called the sliding filament theory. It involves a bunch of tiny proteins, actin and myosin, sliding past each other in an orchestrated little dance that every anatomy and physiology student has to learn.

Hi, I’m Patrick. I’m a freelance science writer based in the San Francisco Bay Area. I hold a bachelor’s degree in Athletic Training and a master’s in clinical exercise physiology. I used to work in the clinical setting as a certified athletic trainer, physical therapy aide, and a certified strength and conditioning specialist. After working in the clinical setting, I went back to school and became a teacher. The goal of my content is to help normal people, not just pre-med students, learn about the human body. That might mean explaining a topic from an anatomy class or exploring a topic from medical history.

The first thing that got me interested in biology was ATP Synthase...followed immediately by the whole process of muscle contraction. Realizing how much of biology is little machines has just blown my mind. I do wish I would have had your video when I first started learning, it was very "clean" I guess I would say. It was a good overview without too much of the nitty gritty.

Hello and thank you for your amazing videos. I wondered what happens in the sarcomere during an eccentric contraction. So..are the myosin and actin still pulling the Z lines closer together but the titin is stretching to allow the muscle to lengthen? Or is there a gradual sort of slippage between the action and the myosin as myosin is ripped off the action? And what actually causes the muscle 'damage' associated with eccentric contractions? Thank you again.

I have a question. At 5:46, you mention the phenomenon of rigor mortis. But: if a sarcomere at rest is RELAXED and NOT contracted, and ATP makes the muscle contract and stiffen/firm up, then by that logic, shouldn't the total lack of ATP lead to total limpness instead of stiffness? Also, if during contraction, the I band shorten and the Z discs get closer together by moving towards the opposite Z disc in and center of every sarcomere, what happens in adjacent sarcomeres? Is there a 'center' that all Z discs in the entire muscle, slide towards? Cause there's no way you can move all of them closer while keeping the lengths of the A band and I band the same length.
