STUDY QUESTIONS FOR TEST 3 (Major concepts)—CHAPTERS 5‚ 6‚ 7 This study guide does not include everything you need to know for the exam. It an overview of main topics that I thought were important in lecture—make sure you’ve studied your book‚ completed the questions at the end of each chapter‚ answered all of the study guide questions‚ and taken the practice exam a few times! I would recommend either writing out the answers or‚ if you’re studying with someone else‚ talk through these questions.

the blood vessel wall and platelets by binding to platelet sur- face receptors and collagen. In addition‚ other platelet surface receptors can bind directly to collagen. 2. After platelets adhere to collagen‚ they become activated; in the platelet release reaction‚ adenosine diphosphate (ADP)‚ thromboxanes‚ and other chemicals are extruded from the platelets by exocytosis. The ADP and thromboxane bind to their respective receptors on the surfaces of other platelets‚ activating them. These activated

cognitive deficits associated with Alzheimer’s while failing to halt the progression of the disease and its neurodegenerative effects. In an attempt to further diverse treatment options for patients currently suffering from Alzheimer’s‚ novel protein receptors in the brain are being examined. Additionally‚ by identifying the structural motifs that define the pharmacophores of molecules which appear to aid in Alzheimer’s

Sannu’s Story A. In Sannu’s case why is there both sensory loss and muscle weakness? Leprosy is a disease that has been known since biblical times. It causes skin sores‚ nerve damage‚ and muscle weakness that gets worse over time. Leprosy is caused by the bacterium Mycobacterium leprae. It is not very contagious and it has a long incubation period (time before symptoms appear)‚ which makes it hard to know where or when someone caught the disease. Children are more likely than adults to get the

with adenosine receptors in the brains makes an individual more alert. A moderate intake of caffeine results in small healthy risks while high doses could be a catalyst to negative effects like anxiety‚ insomnia‚ and tachycardia. Research has shown that caffeine is widely abused. Clinical data available suggest that withdrawal should be considered as a diagnostic manual in the United States (Reissig et al.‚ 2009). The role adenosine contributes

Tactile receptor During anesthesia‚ a complete disruption in sensory perceptions is desired. Which of the following events is NOT associated with the sensory pathway? Action potential generation in a motor neuron Propagation of a signal Depolarization of a receptor All of the listed events are associated with the sensory pathway When you touch a hot stove‚ along which

The primary intervention in the management of dysmetabolic syndrome consists of lifestyle modifications such as cessation of smoking‚ healthy eating of calories restricted diet and increase in physical activity (Falentin‚ 2010). In dysmetabolic syndrome‚ the main emphasis is on reducing the individual risk factors especially in patients identified as high risk of cardiovascular disease and T2DM. Riediger and Clara (2011)‚ state the importance of doctors using a screening tool for other risk factors

blocking the majority of these receptors‚ especially the extrapyramidal syndrome (EPS) which is most bothersome to both patients and doctors putting often an end to treatment. This inconvenience is explained by the following fact: their antagonizing activity is not directed to the mesolimbic receptors specifically‚ and ends up acting on all D2 receptors in the brain causing side effects. When they block D2R in the striatal pathway‚ we have extrapyramidal symptoms resembling those of Parkinson’s disease
