Describe the events at the axon terminal that cause one neuron to release a neurotransmitter onto another. - The action potential travels down the axon and gets to the axon terminal, which causes calcium to enter the axon terinal, which causes the release of the neurotransmitter by exocytosis into the synaptic cleft. The post synaptic neuron, dendrite opens voltage gated channels and allow Na+ in and K+ out. A hypothyroid individual shows no increase in metabolic rate when injected with TSH...
