They act at the end of a synapse. These are where in the nervous system (relay arc) a relay neurone meets a motor neurone.
There is a gap called a synapse between these two neurones and so the only way to transmit the electrical impulse is through neurotransmitters which 'jump' across the gap whilist 'holding' on to the impulse.

What do neurotransmitters open?
Neurotransmitters act on synapses.
What OPEN do?
Neurotransmitters act on synapses.
Have amino acid neurotransmitters not been found yet although a variety of molecules act as neurotransmitters?
False
Inhibitory neurotransmitters of the CNS act by opening gates?
K+ or Cl-
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.
What hormones act as hormones and neurotransmitters?
Epinephrine & Norepinephrine (NE)
What are the biological roles of amino acids?
1. They are the building blocks of proteins. They create polypeptide chains which create DNA (a protein). 2. They can be metabolized to produce energy. 3. They can act as starting material for bio-synthesis of neurotransmitters, hormones and other biochemical compounds. 4. Some can act as neurotransmitters.
Do betalains act as neurotransmitters?
There is no documentation on it. I am also working on betalains but till date I have not come across neurotransmitting activity of betalains.
What are the examples of neurtransmitters?
Examples of neurotransmitters are: acetylcholine, dopamine, norepinephrine, and epinephrine. They also act as hormones but basically they are neurotransmitters that helps send nerve impulses to the brain through axons so that a certain action can be done by a muscle or gland.
How can manipulation of neurotransmitters influence learning and emotions?
Manipulation of neurotransmitters can impact learning and emotions by affecting the communication between neurons in the brain. For example, increasing levels of dopamine can enhance motivation and reward processing, improving learning. Conversely, imbalances in neurotransmitters like serotonin or norepinephrine can lead to mood disorders such as depression or anxiety, affecting emotions.
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!
How do drugs affect the process of synaptic transmission?
They can act in a number of ways, both presynaptically and postsynaptically. They can affect how vescicles release neurotransmitters, how neurotransmitters are cleaved/reuptake, they can block receptors, destroy receptors, agonistically bind to receptors which mimics the neurotransmitter. These are a few.
