10. Explain the contraction of skeletal muscle.
Include: sarcolemma, sarcoplasmic reticulum, Ca2+, actin binding sites, cross bridges, myosin heads, ATP.
Action potential (AP) reaches terminal end of motor
neuron. ACh is released into synapse. Action potential
is initiated in the muscle cell membrane.
Sarcoplasmic reticulum…
