Motor Unit & Action Potential

123456789
Across
  1. 2. made up of a motor neuron and the skeletal muscle fibers innervated by that motor neuron axonal terminals
  2. 4. Connects the motor neuron cell body with the muscle fibers included in the motor unit
  3. 7. a neurotransmitter that stimulates muscle
  4. 8. the flood of positive ions into fiber generates an electrical charges
  5. 9. a link between each axon terminal and muscle fiber
Down
  1. 1. a chemical that discharges and diffuses across the synaptic cleft to attach to receptor on the muscle fiber sarcolemma
  2. 3. a nerve that stimulates skeletal muscle (voluntary)
  3. 5. branches out to individual muscle fibers
  4. 6. a separation for the axon terminal and fibers which is filled with interstitial fluid
