Synapes Flashcards
How do neurotransmitters travel down the neuron axon?
Down the Microtubules
What do the vesicles contain at the synaptic knob?
Neurotransmitters
What is the main neurotransmitter?
Acetycholine
What are voltage gated channels?
They are a cell membrane ion channels which is activated by changes in electrical membrane potential near the channel.
What ion come in at the synaptic knob?
Calcium
What are the two different forms of action potential?
Excitatory & Inhibitory
Would it be cation or an anion would enter the cell to cause depolarisation?
Cation
What is a cation and a anion?
Cation is a positively charged ion and anion is a negatively charged ion
What is summation?
The name given when lots of axon terminals meet dendrites of another cell, rather than one terminal on one dendrite
What are the two different types of Summation?
Temporal Summation - where only 1 terminal ending sends a fast and rapid message.
Spatial Summation - where many impulses are sent from all the terminal ends.
What happens to excess neurotransmitter?
Re-uptake or enzyme breaks it down.
