Webmyasthenia gravis. A condition in which most the cholinergic receptors are destroyed at the motor end plate is known as ____. motor neuron action potential, neurotransmitter release, … WebThe actin and myosin filaments remain in a static position, with the myosin heads attached to actin but not moving. During eccentric contractions, the actin and myosin filaments are sliding past each other, but the tension generated by the cross-bridge cycle is not enough to overcome the external load.
