During a Muscle Contraction The muscle fiber is in a resting state. The resting state is slightly negative inside and slightly positive outside. It has to be in this state in order to receive a message. First the brain sends a message to the muscle using a neuron then reaches the axon terminal of the neuron. Calcium gates then open on the axon terminal allowing calcium to rush in. Ach release from axon terminals‚ diffuses across the synaptic clef and binds to (receptors) on motor end plate. Then
