What is the result of sodium ions moving across the axons membrane during an action potential?
a neural impulse(electrical impulse) is released and it travels down the axon of a neuron to the axon terminals. At the axon terminal there are sacs called synaptic vesicles which contain chemicals called neurotransmitters. When the neural impulse reaches the terminal it causes the sacs to move closer to the membrane of the axon terminal and release the neurotransmitters inside. Then neurotransmitters travel across the synaptic gap and stimulate the dendrites of another neuron and the whole process starts again.
What is a process whereby one neuron communicates with another neuron?
When nerve impulses are triggered near the soma/cell body, an electrical current known as the ACTION POTENTIAL sweeps through the axon and into the axon terminal. When the action potential reaches the tips of the axon terminal, it causes the synaptic vesicles to move towards the membrane of the terminal buttons. The buttons then open up and release the neurotransmitters (drugs.) The neurotransmitter molecules cross over the synaptic gap and attach themselves unto the receptor sites of the other neuron. After accomplishing their work on the receptor sites, some of the neurotransmitter molecules are broken down into other chemicals in a process called Degradation. The rest of the neurotransmitter molecules are taken up by the vesicles for reuse in a process called Reuptake.
Explain the communication process of neurons in the brain?
When transmitting a message, a signal travels through the neuron until the cell ends at the terminal. In order to propagate the signal to the next neuron chemical messengers (neurotransmitters) are released into the inter-neuronal space (synapse). This triggers signal initiation in the second neuron.
What happens to neurotransmitters that fail to attach to a receptor site?
In a process called reuptake, they are reabsorbed by sending the neuron and recycled.
What do the bubbles of chemical crossing the synapse do?
Chemicals called neurotransmitters move across the synaptic gap by diffusion and carry a neural signal across to the receiving neuron. But the 'bubbles' (vesicles) which contained the neurotransmitter chemicals do NOT themselves cross the synaptic gap, they just release the neurotransmitters into the synaptic gap. (The neurotransmitters move across the synapse, the vesicles do not.)The vesicles release their contents of neurotransmitters into the synaptic gap by a process called exocytosis, in which the neural impulse which reaches the terminal button of the presynaptic neuron causes voltage-gated calcium ion pores to open, allowing an influx of calcium ions, which leads to the fusing of the vesicles to the cell membrane, which amounts to the vesicles 'turning themselves inside out' as the membrane of the vesicle merges with the cell membrane, which expels the neurotransmitters into the synaptic gap.The neurotransmitters flow across the synapse to bind with the postsynaptic neuron, potentially triggering neuron excitation (firing) or inhibition (preventing firing).
What is the process by which neurotransmitters reenter terminal buttons and are repackaged for future use in the terminal buttons?
Reuptake
What are retrograde neurotransmitters?
Retrograde neurotransmitters are released from dendrites and alter the activity of neighbouring cells. This process is the opposite of typical neurotransmitters, which are released from the axon terminal (of a post synaptic neuron) and act on dendrites. Two examples are the gaseous neurotransmitters Carbon Monoxide and Nitric Oxide.

reuptake.
What is A terminal that cannot process information?
A "dumb terminal"
What is biopsychology process?
Biopsychology is a branch of psychology which examines how the brain and neurotransmitters affect our thoughts, emotions, and behavior. The bio-psychological process looks at how an impulse, or chemical release from the brain and travelling through the neurotransmitters elicit psychological responses.
What is the process of a neurotransmitter being absorbed into the axon terminal?
The process is called Teuptake
What is a background process?
A background process is a process in computing which is not currently able to receive input from its controlling terminal.

In order to propagate the signal to the next neuron chemical messengers (neurotransmitters) are released into the inter-neuronal space (synapse). This triggers signal initiation in the second neuron.
How does a signal travels down a neuron?
Best Answer: They make chemicals that are gas-like. Neurotransmitters.
