barrier via the L-type amino acid carrier. Excessive levels of Phe in the blood saturates these transporters and subsequently cause a decrease in transportation of other large neutral amino acids into the brain which is required for protein and neurotransmitter synthesis (Blau et al., 2010). Neurological…

Science assignment A lot of young teens or adults experiment with heroin thinking, “I’ll try it once or twice. I can always stop.” But those who start down that road find it nearly impossible to turn back. Heroin is a drug that slows down the messages travelling between your brain and body which can also be classified as a depressant drug a depressant drug, or central depressant drug, is a very commonly used drug for pain relief or endogenous compound that lowers neurotransmission levels, which…

you want your learner to achieve: Example: Anyone who completes this case study should demonstrate knowledge in the area of major depression. Anyone who completes this study should demonstrate the ability to link the function of the imbalance neurotransmitters to the symptoms. Part I: Provide a short description of the “story” you will present and the types of questions you will ask. I have heard of a lot of people who do not believe that psychiatric disorders exist. I want to focus my case…

Neurotransmitters are chemicals responsible for sending information to other cells in the body, and are produced by neurons, nervous system cells, which function is to conduct nerve impulses in the body. The three neurotransmitters related to depression are norepinephrine, serotonin and dopamine (3). Norepinephrine is synthesized from dopamine, and it is related to…

They also cause the release of other neurotransmitters and hormones that affect your mood, appetite, memory, and more. Nicotine exerts its biological effects through nicotinic acetylcholine receptors. When nicotine gets into the brain, it attaches to acetylcholine receptors and mimics the actions…

brain. Certain neurotransmitters are decreased and antidepressants allow the synapses to contain the correct amount of neurotransmitters. There are two main drugs classes—monoamine oxidase inhibitors and tricyclic antidepressants. Monoamine oxidase is an enzyme that breaks down monoamine neurotransmitters and the inhibitors increase serotonin and norepinephrine. Tricyclic antidepressants block the reuptake of serotonin and norepinephrine which allows the levels of these neurotransmitters to…

1. Discuss what a neuron is and the functions of its basic parts (dendrites, soma, axon, myelin sheath). A neuron is a nerve cell. There are about 10,000 specific types of neurons, but there are three most common neurons: sensory, motor, and interneurons. A sensory neuron sends signals to help your brain understand what is going on around you in your environment. Sensory neurons are what make up your senses, (smell, touch, see, taste, and hear.)…

Xanax; the 9th best selling drug in the US as well as the cause of 60,000 hospital admissions each year. I chose to research and talk about the effects of Xanax, also known as Alprazolam. It’s a type of anti-anxiety and sedative drug belonging to the group benzodiazepines. Xanax helps anxiety disorders, panic disorders and anxiety induced by depression. The first benzodiazepine, Librium, was created in 1956 by Leo Sternbach as an alternative to tranquilizing drugs that offered a safer and…

decisions, feelings of guilt, worthlessness, hopelessness and pessimism, helplessness, irritability, loss of interest in activities once pleasurable such as sex and appetite. Serotonin, a neurotransmitter involved in the transmission of nerve impulses, is believed to be related to depression. Since this neurotransmitter has a wide distribution of cells throughout the body, it causes an impact on many psychological…

target areas of research in recent decades. How exactly the brain goes about creating attention is still largely unknown. What is known, however, is that levels of neurotransmitters in certain areas of the brain are responsible for creating a brain environment more favorable to long attention spans. Primarily, the catecholamine neurotransmitters norepinephrine and dopamine have been targeted as being responsible and manipulating the levels of…
