Hint: acetylcholine

Answer 1

1) A action protein is going to move down the action of the motor neuron
2) which moves through the telondendria transmitting information between the vesicles and motor end plate. the sarcolemma where a electrical charge occurs
3) releasing a chemical that transmit a message from the receptors acetylcholine binding the cell within the synaptic cleft
4) acetylcholineterase (ACHE) pulls out The acetylcholine and places it back into the muscle cell to use it (recycle)
5) and molecules are attached to the sea lions, boundaries of the Sack of mirrors, shortens the sacraments according to the sliding filament theory
