  4. Action potential of muscles

  5. Ions (charge elements) build up until • Na+ (sodium) gathers outside the membrane • K+ (Potassium) gathers inside the membrane • A signal from another nerve opens the channels, and the Na+ rushes in. K+ rushes out. • This repeats jumping down the nerves. • At the end of the nerve, Acetylcholine has been building up. • When the impulse reaches the neuromuscular junction, Acetylcholine channels are open, allowing it to rush out and trigger a muscle contraction.

  6. Reflection: Would you consider working for Youth Outdoors?
