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