What is a presynaptic knob?
The transmitting cell at the synapse
What is the post synaptic knob?
The receiving cell at the synapse
What are neurotransmitters?
Chemical messages that pass information from the transmitting neuron to the receiving neuron
What to receptor sites do?
Bind with neurotransmitters
How to neurotransmitters pass across the post synaptic knob?
They diffuse across because of the concentration gradient
What carries neurotransmitters through the presynaptic knob?
Vesicles
What clears out neurotransmitters that aren’t used
Enzymes
Where do the neurotransmitters that aren’t used go?
Recycled back into the vesicles
What are the two types of synapses?
Excitatory synapse
Inhibitory synapse
What is an excitatory synapse?
Neurotransmitters that are sent to attempt to get the post synaptic neuron to fire
What is an inhibitory synapse?
Neurotransmitters that are sent to attempt to prevent the post synaptic neuron to fire
Where does a synapse occur?
Between two neurons
