What is the correct order of a signal being transmitted across a neuromuscular junction?

For the purposes of this discussion, a neuromuscular junction is a synapse between a motor neuron and a skeletal muscle. 
The correct order of a signal being transmitted across a neuromuscular junction is as follows:1. The brain must first send the signal to the muscle that it must move.2. The muscle must then be stimulated by a motor neuron. In other words, the stimulatory impulse must travel from the motor neuron  to the muscle via the synapse. 
If the command or signal is correctly sent and received via the neuromuscular junction, the muscle will move otherwise the muscle will not move as the brain signal indicated. 

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
