Unformatted text preview: is activated, a neural impulse is sent down this part of the neuron into the terminal branches the Terminal Branches (AKA terminal boutons): the ends Terminal of the axon that branch out and are responsible for the release of the neurotransmitter that is needed for the communication with other neurons communication Neural Communication Neural The action potential - an all-or-none signal that is The sent along the axon of the neuron sent Starts at the axon hillock Involves an exchange of positively and negatively charged ions It does not fade over time or distance When an action potential When reaches the terminal branches it initiates the release of neurotransmitters into the synapse into Synapse: the space Synapse: between the axon’s terminal button and the dendrite of the subsequent neuron neuron This neurotransmitter This connects to the dendrites of a nearby neuron and either increases or decreases the likelihood of that cell firing likelihood Once a neurotransmitter has been released into Once the synapse, three things can occur to them the Activation: the neurotransmitters can temporarily Activation: cling to the dendrites of another neuron, and influence this neuron based on the type of neurotransmitter that was released neurotransmitter Reuptake: the axon terminal can eventually “suck Reuptake: back” the neurotransmitter that it released (recycling at its best) at Diffusion/Metabolized: the neurotransmitter can be Diffusion/Metabolized: broken...
