Muscle Contraction 101 Action Potential (AP) in the (ORGAN) conducts from motor neurons to skeletal musde. Once the Impulse reaches the muscle, (ALSO FOUND IN MILK) is released from the storage area 12 WORDS). Transported by T- tubules, calcium binds to (REGULATORY PROTEIN) resulting in myosin sites on actin becoming available. The globular heads on (CONTRACTILE PROTEIN) bind to actin with the energy of (CURRENCY IN CELL). This connection is called a (GOLDEN GATE IS ONE). When the myosin heads “disconnect” from actin and the distance from 2-line to Z-line decreases, it is called the (FORCEXDISTANCE/TIME + STROKE). The act of how the muscle contracts is known as the (“THEORY”), 3 conditions that must be present for muscle contraction to occur
