What is cardiac muscle?
During rigor mortis, _____________ floods the muscle fibers but a lack of _______________ prevents it from detaching.
What are Calcium and ATP?
Amount of ATP used in each myosin/actin cross-bridge cycle.
What is 1?
The other myofilament essential to muscle contraction besides myosin.
What is actin?
When myosin heads make a cross bridge and bend pulling the actin myofilament towards the sarcomere, it is called the ________________.
