What is contractility?
Where a motor neuron and a muscle fiber come together
What is Neuromuscular junction?
Connective tissue sheath that surrounds the entire muscle

Make up Sarcomere and have the names Actin & Myosin
What are Myofilaments?
The boundary between sarcomeres
What is the Z Line?
For Excitability what happens when your motor neurons deliver on impulse to a muscle ?
