Question 1

what is the process of synaptic transmission?

Answer 1

• nerve impulse travels down the axon
• then reaches synaptic terminal at presynaptic membrane and triggers release of neurotransmitters
• fired into the synaptic gap
• the neurotransmitters bind with receptors on the dendrite of the post synaptic neuron
• post synaptic receptors are activated by the neurotransmitter and either increase or decrease likelihood that the post synaptic neuron will fire an action potential
• eventually neurotransmitter molecules are cleared from synaptic gap via reuptake or via enzymes breaking down the transmitter
