Following the end plate potential there is a wave of depolarization that causes voltage gated sodium channels to open resulting in more sodium entering the cell Acetylcholine ACh binding to its receptors causes voltage gated sodium channels to open producing an end plate potential Sodium entering in to the cell causes depolarization and potassium exiting from the cell causes repolarization Acetylcholine ACh released by the motor neuron diffused across the synaptic cleft and binds to its receptors on the muscle fiber s sarcolemma Question 14 2 points 4 Listen Select ALL of the following that are true regarding the microscopic anatomy of skeletal muscles Dystrophin helps bind sarcomeres together and helps maintain the alignment of sarcomeres Elastic filaments which are composed of the protein elastin helps the myofibril recoil after stretching and helps resist excessive stretching Thick filaments consists of many myosin molecules each of which has two heads and a tail region
