Excitatory neurotransmitter usually is acetylcholine. To get inhibitory responses in a nerve cell, the arrangement of receptors is different. The study of nervous system in detail will provide you exact answer to your question.

What effect do neurotransmitters from one neuron have on the next neuron?

Neurotransmitters released from one neuron can either excite or inhibit the next neuron. Excitatory neurotransmitters make the receiving neuron more likely to fire an action potential, while inhibitory neurotransmitters make it less likely. This process allows for communication and coordination between neurons in the nervous system.


How do psychoactive drugs affect the brain?

Psychoactive drugs can affect the brain by altering neurotransmitter levels, specifically dopamine, serotonin, and norepinephrine. They can also impact neural pathways and structures, leading to changes in mood, perception, cognition, and behavior. Chronic use of these drugs can disrupt normal brain functioning and lead to addiction or other long-term consequences.


How do neurotransmitters transmit signals across the synapse?

after impulse conductionby postsynaptic neurons is initiated, neurotransmitters activity is rapidly terminated. Either one or both of two mechanisms cause this. Some neurotransmitters molecules difuseout of the synaptic cleft back into synaptic knobs


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.


How a neuron sends internal messages?

Neurons send internal messages through the use of action potentials, which are generated through the summation of inputs from the dendrites on the other part of the neuron. These inputs are summed either temporally (over a period of time) or at the same time (instantaneous), and if they push the voltage in the zone of the axon hillock to above threshold, it results in the generation of an action potential. The action potential travels through the axon, and once it reaches the terminal bouton of the axon, it triggers calcium influx into the cell, which causes neurotransmitter release. Neurotransmitter release may either be excitatory or inhibitory depending on the neurotransmitter released; for example, in the CNS, glutamate is the major excitatory neurotransmitter, whereas GABA is the major inhibitory neurotransmitter. They bind to the post-synaptic cell, which triggers the post-synaptic cell response. Note that this is just a general overview for neural transmission; some neurons may have different mechanisms of action.

A neuron has hundreds of axonknobs impinging on it and most of the axonal knobs are firing but why does the neuron not transmit an impulse?

Probably because some portion of those synapses are inhibitory as opposed to excitatory.


What are neuro transmitters?

The nervous system is composed of many cells called neurons, these are essentially the functional units of the nervous system. ?Neurotrnasmitters are chemical messengers that are sent from one neuron to another neuron. ?So basically they are messangers communicating from one neuron to the next. ?Some neurotransmitters are excitatory which act to help activate a neuron, some neurotransmitters are inhibitory and act to reduce excitement of a neuron. ?Many many neurotransmitters will act on a neuron at a given time and the sum total will result in either an excitation or inhibition of that neuron. ?Examples of neurotransmitters include GABA, glutamate, serotonin, dopamine, acetylcholine, histamine, ?glycine, epinephrine, norepinephrine, melatonin, substance P, and many more!

What are the excitatory neurotranmitters?

Glutamic acid (glutamate) is probably the most abundant excitatory transmitter. Others can be excitatory, such as acetylcholine, and some peptides. Aspartate is also excitatory. Finally, serotonin is often found to be exctitatory.

How does the end plate potential differ from a EPSP on a post synaptic cell?

End plate potential is the change in potential from neurotransmitters. It can be excitatory or inhibitory. If the action potential wants to continue, it will be excitatory and vice versa. It can be additive, if more action potentials are fired it will increase the end plate potential. An action potential is an all or none response. It will either proceed or it will not proceed depending on the terms of the threshold. It cannot be additive, because there is an absolute refractory period where no additional action potentials can be fired.

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 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.
