Synaptic Transmission (IB Biology)

Which of the following events corresponds to number 1 on the diagram?

• Neurotransmitter binds to receptors on the post-synaptic neuron's membrane

• Nerve impulse arrives in the pre-synaptic nerve ending

• calcium channels in the plasma membrane open (calcium ions enter the pre-synaptic neuron)

• Sodium ion channels open in the pots-synaptic neuron

Which of the following events corresponds to number 2 on the diagram?

• Sodium ions flood into post-synaptic neuron, depolarize the resting potential and nerve impulse is created.

• Vesicles of neurotransmitter fuse with the membrane of the pre-synaptic axon ending

• Calcium channels in the plasma membrane open (calcium ions enter the pre-synaptic neuron)

• Sodium ion channels open in the pots-synaptic neuron
