How Nerves Communicate Flashcards
The neuron sending the signal is known as the _ neuron
Pre-synaptic
Neuron receiving signal called the _ neuron
Post-synaptic
Gap means _ cannot flow directly from one neuron to the next
Electrical nerve impulse
When nerve impulse reaches the synaptic terminals, sudden change of voltage causes _ to flow into pre-synaptic terminals
Calcium
Vesicles are small, membrane-bound sacs containing _
Chemical messengers called neurotransmitters
Calcium ions cause vesicles to move towards and dock with _
Pre-synaptic cell membrane
Vesicles then release contents into _
Synaptic gap
Neurotransmitters molecules diffuse across post-synaptic cell and activate _ located within its membrane
Receptor proteins
Neurotransmitter molecules can either excite or inhibit post-synaptic cell, depending on neurotransmitters and its associated _
Receptor
