What is third class lever?
The contractile unit of muscles
What is the sarcomere?
Similar to lifting a wheelbarrow.
What is second class lever?
Binds to actin to make room for myosin.
What is the role of calcium?
The load and the effort are close together.
What is mechanical advantage?
A function of muscle tissue.
What is Movement (skeletal muscle), Protection (over organs), Posture (bipedal motion), Guards entrances and exits (sphincter), Thermoregulation (homeostasis).
The process of muscle contraction.
What is ATP attaches to the myosin head, allowing it to connect to the actin and pull the actin forward.
Lift with your back, not your legs - True or False (and explain why!)
