Sensory Receptors: Detect environmental changes and trigger nerve impulses that travel on sensory pathways into the central nervous system for processing and interpretation. 2. Somatic Senses: Touch‚ pressure‚ temperature‚ and pain 3. Special Senses: Smell‚ taste‚ hearing‚ equilibrium‚ and vision 4. 5 groups of sensory receptors: Chemoreceptors‚ Pain receptors‚ thermoreceptors‚ mechanoreceptors‚ and photoreceptors. 5. The process

shown that formoterol has more than 200-fold greater agonist activity at beta2-receptors than at beta1- receptors. Although beta2-receptors are the predominant adrenergic receptors in bronchial smooth muscle and beta1-receptors are the predominant receptors in the heart‚ there are also beta2-receptors in the human heart comprising 10%-50% of the total beta-adrenergic receptors. The precise function of these receptors has not been established‚ but they raise the possibility that even highly selective

When it comes to burning fat in the body‚ we are not talking about a partial reduction. The attack on the stubborn stored fat is not the same thing as partial reduction! Partial reduction is associated with the practice‚ while burning body fat refers to proper nutrition‚ proper training and quality supplementation! The release of the fat in the body is certainly possible‚ only if you know what to do‚ when and how. So‚ when we say "stubborn fat" mean the subcutaneous fat. They are much more difficult

The Physiology and Pathophysiology of the Skin Abstract The 5-HT3 receptor is a ligand-gated cation channel located in the central and peripheral nervous system; it has also been detected on a variety of other cells. In the periphery‚ it is found on autonomic neurons and on neurons of the sensory and enteric nervous system. In the CNS‚ the 5-HT3 receptor has been localized in the area postrema‚ nucleus tractus solitarii‚ nucleus vaudatus‚ nucleus accumbens‚ amygdala‚ hippocampus‚ entorhinal‚

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

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.

In an attempt to further diverse treatment options for patients currently suffering from Alzheimer’s‚ novel protein receptors in the brain are being examined.

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
