180
What is the role of the neurotransmitter in muscular movement?

181
What happens during action potential?
ACH diffuses across the synaptic cleft attaching to receptors in the post synaptic cell
Cell membrane permeability changes and a signal called action potential is generated.
NA+ ions leave the external fluid compartment and the internal fluid compartment. K+ ions leave the ICF and enter the ECF
182
How does calcium influence action potential?
Ca+ ions ensure contraction and relaxation of a muscle cell.
183
What returns the muscle cell to its resting state?
When ca+ decreases, tripping returns to its normal structure. Tropomyosin blocks the sliding action and movement is stopped - muscle relaxes
