Neurotransmitter

Cell-Cell Communication in Taste Buds: Activation of Type II cells by taste stimuli causes the release of ATP through pannexin hemichannels and/or CALMH1 channels. The released ATP or sour stimuli can activate Type III cells and causes release of different hormones such as 5-HT and NE via Ca2+-dependent exocytosis. In some instances NE is co-released with 5-HT (Dvoryanchikov et al., 2007; Huang et al., 2008a). The ATP released by Type II taste cells acts as a paracrine as well as an autocrine…

Pharmacology- Practical based exercise Introduction/ aims Acetylcholine (ACH) is a neurotransmitter which operate in the brain, ACH are known as cholinergic because they are released from both the parasympathetic and sympathetic systems, (Colovic, 2013). There are drugs which look to copy these effects or inhibit them, they are known as cholinergic drugs. ACH has two types of receptors, nicotinic and muscarinic receptors. Nicotine acts as antagonists for nicotinic receptors, by blocking these…

we increase the concentration of Fernaldia in the group of neurons, we can find a decrease in the concentration of neurotransmitters in the vesicles and a decrease and an increase in the concentration of degraded neurotransmitter components in the cytosol. This supports the statement that there are fewer neurotransmitters in the synaptic cleft since there are fewer neurotransmitters in the synaptic vesicles. Alternative hypothesis: However, the predicted results could also support an…

The neurotransmitter that I chose to research is serotonin. It is created by a biochemical conversion process that combines tryptophan, a part of proteins, with tryptophan hydroxylase, a chemical reactor. Together, they form 5-hydroxyltryptamine (5-HT). Serotonin is manufactured in the brain and the intestines. The majority of the body's serotonin, between 80% to 90%, can be found in the gastrointestinal (GI) tract. It can also be found in the blood platelets and the central nervous system.…

Is there a biological predisposition to crime? In my personal experience I have had friends who fit this theory and ones that have busted this theory. One of my friends from high school who is currently in prison now for stabbing someone would be a perfect example of the biological theory. Practically all of his cousins and himself had been in some sort of detention center for narcotics or fighting. It will be interesting to see if his son ends up the same way as he did. On the other hand I had…

This study analyzed the differences and the relationships of the isolated sciatic nerve in regards to the compound action potential and the neuromuscular junction stimulations of the Rana pipens gastrocnemius. A total of five exercises were used to identify the effects on the stimulation of the sciatic nerve and the gastrocnemius. A dissection for both labs were performed to isolate the nerve and to isolate the gastrocnemius. Both experiments used LabChart to perform various stimulations on the…

History Parkinson disease was coined by James Parkinson, an English apothecary surgeon, political an activist, paleontologist and geologist in 1817. He described the disease as a shaking palsy that involves resting tremor, diminished muscles strength, paralysis, unusual posture and gait, and how it progresses overtime. Sixty years later, Jean Martin Charcot, a French neurologist and professor of anatomical pathology, also the founder of modern neurology. He clearly defined the disease as a slow…

1. Do all plants contain gluten? Make a list of plants that contain gluten. (1 pt) Not all plants contain gluten, but some plants like wheat, rye, and barley are packed with the protein, gluten. Gluten is one of the “most heavily consumed proteins on earth, and is created when two molecules, glutenin and gliadin, come into contact and form a bond” (Specter). Plants that contain gluten include: ➢ Wheat ➢ Rye ➢ Barley ➢ Bulgur ➢ Seitan ➢ Triticale ➢ Mir 2. What are some known health issues…

ALS is a multi-factorial neurodegenerative disease that affects the upper and lower motor neurons of the spinal cord. It is found in both familial and sporadic forms. Familial ALS is recognized by mutant SOD1 which fails to convert reactive oxygen species to hydrogen peroxide and/or water; however, studies have shown the presence of SOD1 aggregates in sporadic forms as well (Redler and Dokholyan, 2012). This is due to the ability of wild-type SOD1 to become toxic due to oxidative stresses in the…

At the spinal level, the PNS and CNS are bilaterally symmetrical. And studies have shown that the two sides of the spinal cord are not independent due to the findings that unilateral peripheral nociception results in contralateral responses (Koltzeburg, 1999). The contralateral pain was perceived at a lesser magnitude and has a delayed response. This contralateral pain phenomenon can be attributed to a similar pathway as central sensitization leading to secondary hyperalgesia. Primary…
