Skeletal muscle contraction Flashcards
1
Q
What is the result of muscle contraction?
A
shortening of sarcomeres- pulling of the muscle against its attachment
2
Q
What is the pulling force exerted by?
A
The binding of myosin molecules to actin molecules
3
Q
What does the shortening of a muscle fibre results from?
A
An increase in the overlap between actin and myosin filaments- as they slide past each other
4
Q
What does shortening of muscle fibre result in?
A
Shortening of the entire muscle, which then pulls on the attached body part to cause movement
