Which of the following drugs is Neurotransmitter?
A. Largactil
B. Tramadol
C. Dopamine
D. Lithium
Correct Ans: (C). Dopamine
Explanation: Examples of excitatory neurotransmitters include glutamate, epinephrine and norepinephrine. Inhibitory- Inhibitory neurotransmitters block or prevent the chemical message from being passed along any farther. Gamma-aminobutyric acid (GABA), glycine and serotonin are examples of inhibitory neurotransmitters.
The questions asked by most people are given below (FAQ)
Q. Which of the following is a neurotransmitter?
Ans: The best known neuromodulators are also neurotransmitters, such as dopamine, serotonin, acetylcholine, histamine, and norepinephrine. Other associated chemical substances include neurohormones. They are synthesized in neurons and secreted into the bloodstream which carries them to distant tissues.
Q. What are the names of neuro drugs?
Ans: Anticonvulsants such as levetiracetam (Keppra), topiramate (Topamax), lamotrigine (Lamictal), oxcarbazepine (Trileptal), and divalproex sodium (Depakote) are some of the most commonly prescribed neurological medications.
Q. What are the 4 major types of neurotransmitters?
Ans: Neurotransmitters are chemical messengers that help nerve cells communicate with each other. They include serotonin, dopamine, glutamate, and acetylcholine. Neurotransmitters serve several functions, such as regulating appetite, the sleep-wake cycle, and mood.
Q. Which of the following are hormones and neurotransmitters?
Ans: The two hormones that are also neurotransmitters are adrenaline (epinephrine) and dopamine.
Q. What is the most common neurotransmitter?
Ans: The most common neurotransmitter is acetylcholine, which often is the messenger between axons and muscles as well. Other common neurotransmitters are octopamine, serotonin, and dopamine; they usually function in the central nervous system. All of these neurotransmitters are found in both vertebrates and invertebrates.
Q. Where are neurotransmitters used?
Ans: Neurotransmitters are chemical messengers that your body can’t function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland.
Q. What are neurotransmitters used for?
Ans: Neurotransmitters are often referred to as the body’s chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles. Communication between two neurons happens in the synaptic cleft (the small gap between the synapses of neurons).
Q. Where are neurotransmitters accepted?
Ans: Chemicals, called neurotransmitters, are released from one neuron at the presynaptic nerve terminal. Neurotransmitters then cross the synapse where they may be accepted by the next neuron at a specialized site called a receptor.
Q.What is the main function of a neurotransmitter using an example?
Ans:Neurotransmitters relay their messages by traveling between cells and attaching to specific receptors on target cells. Each neurotransmitter attaches to a different receptor. For example, dopamine molecules attach to dopamine receptors. When they attach, it triggers an action in the target cells.
Q. How are neurotransmitters used in everyday life?
Ans:These messages are vital for your daily functions, including the movement of your limbs, the ability to feel sensations, and your response to information from internal body parts and your environment. In addition, the messages passed along by neurotransmitters help to keep your heart beating.
Q. What neurotransmitters are most important?
Ans: From our point of view the most important neurotransmitters are, in alphabetical order, acetylcholine (associated with Alzheimer’s disease and myasthenia gravis), dopamine (Parkinson’s disease), glutamate and GABA (epilepsy and seizures), and serotonin (major depression.
