The word synaptic is an adjective which means, pertaining to the synapses. So, I could describe dopamine as a chemical that has a synaptic function, as a neurotransmitter.
synaptic potential
synaptic vesicles
If it's a synaptic gap then the answer would be neurotransmitter.
synaptic cleft (also known as "synaptic gap")
The nerve signal arrives at a synaptic knob and causes calcium channels to open. This allows the calcium ions to enter the synaptic knob. Calcium ions entry into the synaptic knob triggers exocytosis of synaptic vesicles, which release acetylcholine into the synaptic cleft.
Yes
Synaptic gaps are the spaces between neurons.
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.
What is the role of synaptic potentials in the perception of pain? What kind of reaction might you expect if synaptic potentials were removed?
Calcium ions enter the presynaptic neuron resulting in the release of neurotransmitter from the per-synaptic membrane. The neurotransmitter diffuses across the synaptic cleft, fusing with the receptors of the post-synaptic membrane. This changes the sodium channels to open and sodium ions will to flow into the post-synaptic neuron, depolarizing the post-synaptic membrane. This initiates an action potential. After the post-synaptic neuron has been affected, the neurotransmitter is removed by a type of enzyme called cholinesterase. The inactivated neurotransmitter then returns to the pre-synaptic neuron.
