Synaptic transmission

Cards (6)

What are the 2 effects Neurotransmitters can have on a neuron?
Excitatory or inhibitory
What are Neurotransmitters?
Chemicals that diffuse across the synapse to the next neuron in the chain
each NT has its own specific molecular structure that fits perfectly into a post-synaptic receptor site.
Neurotransmitters also have specialist functions
What happens when electrical impulses reach the end of the neuron (the presynaptic neuron)?
It triggers the release of neurotransmitters from tiny sacs called synaptic vesicles
How are signals transmitted between neurons?
Chemically
How are signals transmitted within neurons?
Electrically
How do neurons communicate with each other?
Within groups known as neural networks
