- AP
- An AP opens the Ca2+ channels on the membrane of the neuron's synaptic terminal
- Ca2+
- Ca2+ Channel
- Ca2+ from the synaptic terminal diffuses into the neuron
- Synaptic Terminal
- Ca2+
- Neuron
- ACh is released from the synaptic vesicles
- ACh
- Synaptic Vesicle
- A robber (AP) busts a thief (Ca2+) out of his cell (Ca2+ channel) within jail (synaptic terminal).
- ACh binds to Na+ channels on the sarcolemma
- ACh
- Na+ Channel
- The thief (Ca2+) runs from jail (synaptic terminal) into the city (neuron)
- An AP is generated and moves down the sarcolemma into the t-tubules
- APs Spreading
- The ringleader (ACh), senses that time is right, and breaks out of Alcatraz (synaptic vesicles), where he was being held
- The AP allows Ca2+ channels to open and release Ca2+
- Ca2+ Channel
- Ca2+
- Ca2+
- The ringleader (ACh) then opens up other jails (Na+ channels) around the city (sarcolemma)
- As a result, a massive wave of crime (AP) blankets the city (Sarcolemma t-tubules)
- This wave of crime (AP) empowers other thieves (Ca2+) to break out of their cells (Ca2+ channels) in the city jail (TC SR)
