What is a synapse?
Describe the structure of a synapse
Complete the sentences:
There are different types of synapses, each with a slightly different __________ that relates to their function. A _________ synapse uses the neurotransmitter _________________ (ACh) which binds to cholinergic receptors.
Outline the method of synaptic transmission
Synaptic transmission can be affected by chemicals like...
How do chemicals affect synaptic transmission?
Give an example of a chemical that has the same shape as neurotransmitters (agonists)
Give an example of a chemical that blocks receptors (so they can't be activated by neurotransmitters)
Give an example of a chemical that inhibits the enzyme that breaks down neurotransmitters
Give an example of a chemical that inhibits the release of neurotransmitters from the presynaptic neurone
What is synaptic divergence?
What is synaptic convergence?
What is spatial summation?
Complete the sentences:
In spatial summation, the small amount of ____________________ released from each of these neurones can be enough altogether to reach the __________ in the postsynaptic neurone and trigger an _________ potential. Stimuli might arrive from different sources, but spatial summation allows signals from multiple __________ to be coordinated into a single response.
What is temporal summation?
TRUE OR FALSE:
Temporal summation makes an action potential more likely
Synapses make sure impulses are unidirectional. What does this mean?
How do synapses make sure that nerve impulses are unidirectional?
