| True or false, the neuromuscular juncion is a speicalized elecrtical synapse? |
| False, it is a specialized chemical synapse comprised of an Alpha motor neuron and the muscle fiber it innervates |
| True or false, usually each muscle fiber has only one neuromuscular junction? |
| True or false, a single muscle fiber is controlled by a single motor unit? |
| Where does the junction of nerve endings meet on the muscle fiber? |
| midpoint to allow the action potential to travel in each direction |
| Where is the active zone of the axon terminal located? |
| What is a motor unit consist of? |
| A single motor neuron and all the muscle fibers it innervates |
| True or False, a synapse will always respond to an action potential? |
| False, a synapse may or amy not respond whereas a junction will always respond to an action potential. |
