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