Action potentials trigger the release of chemicals in the terminal buttons called?
neurotransmitters. These neurotransmitters are released into the synaptic cleft to relay signals to the next neuron in the communication pathway.
Why would a psychologist pay attention to neurotransmitters?

Explain how neurotransmitters affect behavior?
Neurotransmitters are chemical messengers that transmit signals between neurons in the brain. They play a crucial role in regulating mood, emotions, and behavior. Imbalances in neurotransmitter levels can lead to various mental health disorders, such as depression, anxiety, and schizophrenia, impacting behavior and cognitive functions. By influencing communication among brain cells, neurotransmitters can modulate behavior by affecting processes like reward, motivation, and stress response.
Do dendrites release neurotransmitters?
Not really, but sort of, eventually. Initially they receive neurotransmitters which are originally released by axon terminals into the synaptic cleft; then, after they have done their job of opening ligand-gated ion pores to allow sodium ions into the dendrite, which initiates a graded potential in the dendrite, they are then released so they can be re-absorbed and re-used by the axon terminals as new impulses reach the axon terminals.But functionally it is the axon which releases neurotransmitters, when an action potential causes it, so that dendrites can receive them. The dendrites only "release" them after their job is done, so they can be re-used.
What role do neurotransmitters play in human behavior?
Humans (as well as many other mammals and other lifeforms) transmit information across their bodies through the use of neurons. At the axon ends of these neurons are tiny sacs called synaptic vesicles that contain special chemicals called neurotransmitters. Since neurons aren't physically connected to one another, they have to releases these neurotransmitters and then have them received by receptors on another neuron. Thus, in order for any behavior to actually present itself in a physical form, a series of messages must be sent from the brain to another part of the body along these neurons through the use of neurotransmitters. Since these neurotransmitters are just freely floating in the body, its easy for them to be modified by external forces. If for example your body wanted to dilute some pain, it could release chemicals that would stop neurotransmitters that would otherwise tell your brain that you're in pain.
Can you give me the names of all the neurotransmitters?
Here's a beginning. the related question below list the essential neurotransmitters.
What are the names of some common neurotransmitters?
Acetylcholine or aka ACH is the neurotransmitter that is released from the axon terminal to through the neuromuscular junction across the synaptic cleft which binds to the ACH receptors on the end motor plate of the Sarcolema.
What do neurotransmitters open?
Neurotransmitters act on synapses.
What susbstance is found in synaptic vesicles of axon terminal?
Neurotransmitters are the substances found in synaptic vesicles of axon terminals. These neurotransmitters are released into the synapse, where they transmit signals from one neuron to another. Some common neurotransmitters include dopamine, serotonin, and acetylcholine.
What neurotransmitters are amino acids?
define amino acids in neurotransmitters
Which structure in the body releases neurotransmitters?
Neurons release neurotransmitters.
How many different kinds of neurotransmitters do you release into your synapses?
There are over 100 different types of neurotransmitters that can be released into synapses, each with specific functions and effects on neuronal communication. Some of the most well-known neurotransmitters include serotonin, dopamine, and glutamate.
What does an axon release when an impulse reaches the end of it?
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
What are considered not true neurotransmitters?
Not all molecules that act as neurotransmitters in the brain are considered "true" neurotransmitters. Some molecules, like gases (e.g., nitric oxide), lipids (e.g., endocannabinoids), and peptides (e.g., endorphins), can also act as neurotransmitters but are not classified as traditional neurotransmitters like dopamine or serotonin due to their unique chemical properties and modes of action. These non-traditional neurotransmitters play important roles in modulating neural signaling and can have significant effects on behavior and physiology.
What are some important neurotransmitters?
Acetylcholine, adrenaline, noradrenaline, serine GABA. dopamine etc.
What releases neurotransmitters into the synapse?
Neurotransmitters are released into the synapse by the presynaptic neuron.
Are neurotransmitters that depress the resting potential called excitatory?
No, neurotransmitters that depress the resting potential are called inhibitory neurotransmitters. Excitatory neurotransmitters have the opposite effect, causing depolarization and increasing the likelihood of an action potential.
