What drug blocks blocks the release of the neurotransmitter?
An example of a drug that blocks release of a neurotransmitter is botulinum toxin (Ach) and atropine.
What are two neurological drugs?
Nicotine is one of the most common drugs that acts on the nervous system. It binds to the same receptors that acetylcholine binds to, creating a similar excitatory effect. This is why nicotine is a stimulant. Nicotine also facilitates the release of dopamine in the brain, giving smokers that relaxed, more alert feeling. Another drug that affects the nervous system is alcohol. In low doses, it acts as a stimulate, partially because it acts on glutamate receptors (glutamate is the most common excitatory neurotransmitter in the brain). However, in high doses, alcohol is a depressant, acting on GABA receptors (GABA is a major inhibitory neurotransmitter). Alcohol causes motor, cognitive, verbal, and perceptual impairments. However, nicotine is one of the most addictive substances in the United States, and both drugs have serious side effects on other areas of the body.
Cholinergic synapses release what neurotransmitter?
acetylcholine (ACh)
Into what does the neuron release its neurotransmitter at the neuromuscular junction?
cytoplam
Cocaine cause the sudden release the brain of a neurotransmitter called?
True. Cocaine causes the sudden release in the brain of a neurotransmitter called dopamine. Source. Prentice Hall
What are the release dates for In the Nicotine - 1961?
In the Nicotine - 1961 was released on: USA: June 1961
Why is it important for the neurotransmitter substance to be deactivated soon after its release?
It is important for the neurotransmitter to be deactivated soon after its release so that actional potential generation can be stopped when the organism doesn't need it any more.
How can nicotine effect the brain?
Your brain is made up of billions of nerve cells. They communicate by releasing chemical messengers called neurotransmitters. Each neurotransmitter is like a key that fits into a special "lock," called a receptor, located on the surface of nerve cells. When a neurotransmitter finds its receptor, it activates the receptor's nerve cell. The nicotine molecule is shaped like a neurotransmitter called acetylcholine. Acetylcholine and its receptors are involved in many functions, including muscle movement, breathing, heart rate, learning, and memory. They also cause the release of other neurotransmitters and hormones that affect your mood, appetite, memory, and more. When nicotine gets into the brain, it attaches to acetylcholine receptors and mimics the actions of acetylcholine. Nicotine also activates areas of the brain that are involved in producing feelings of pleasure and reward. Recently, scientists discovered that nicotine raises the levels of a neurotransmitter called dopamine in the parts of the brain that produce feelings of pleasure and reward. Dopamine, which is sometimes called the pleasure molecule, is the same neurotransmitter that is involved in addictions to other drugs such as cocaine and heroin. Researchers now believe that this change in dopamine may play a key role in all addictions. This may help explain why it is so hard for people to stop smoking.

The ion needed to initiate the release of a neurotransmitter into the synaptic cleft is?
Ca2+
What ion triggers the release of a neurotransmitter at the presynaptic membrane?
Calcium triggers synaptic vesicles to discharge the neurotransmitter into the synaptic cleft.
Is calcium a neurotransmitter?
No, calcium itself is not a neurotransmitter BUT it is highly important in the process of the action potential. The action potential triggers the influx of calcium at the end of the terminal bouton, causing the influx of Ca2+ into the cell and this triggers for the release of the neurotransmitter. :)
