P5 – Physical and psychological theories of ageing Physical changes Hormones and Menopause: When it comes to hormones and menopause Alicia may have had a decrease in the hormone oestrogen which is known to be connected with the osteoporosis. This would have caused Alicia to be at some kind of risk of osteoporosis than others if she had genetically inherited it. However‚ to prevent osteoporosis Alicia could had exercise sessions or any different type of fitness which would have helped her strengthen

Homeostasis Homeostasis Is a technical term for the process of maintain a constant internal environment despite external changes. The internal environment‚ compromises; blood‚ tissue fluid‚ body cell contents and all the metabolic processes taking place. Constant in this instance is not absolute or fixed it is much more flexible and dynamic as it refers to the physical and chemical composition being kept within a limited range or variables for maximum efficiency‚ well-being of the whole body and

Retarding compounds prevent blood clotting. *Thromboses - Coagulate blood and foster clot formation throughout the circulatory system. *Haemolysis - Destroy red blood cells. *Cytolysins - Destroy white blood cells. *Neurotoxins - Block the transmission of nerve impulses to muscles‚ especially those associated with the diaphragm and breathing. Every snake has a different amount of the aforementioned agents its venom‚ hence the differing levels of toxicity. Throughout this report‚ the examination

Running Head: SYNAPTIC TRANSMISSION Synaptic Transmission Grand Canyon University PCN 310 Synaptic Transmission They can proceed in several ways‚ both presynaptically and postsynaptically. They can influence how vesicles issue neurotransmitters‚ how neurotransmitters are cleaved/reuptake‚ they can hinder receptors‚ destroy receptors‚ and agonistically join to receptors which mimic the neurotransmitter. These are a few. Synapses are vital to the function of the nervous system. The most

The Mechanics of Water The Science of Nutrition Perhaps you have heard the phrase “water is life”. When it comes to the human body‚ nothing could be more accurate. The system of fluids in the body that water affects controls everything from nerve impulse to movement; it is even part of the very structure of our bodies. The following will discuss the vital connection between different systems in the body and how they use water to maintain proper health and function. We will discuss what happens

The action of ANS-related drugs on smooth muscle Introduction In the following experiment‚ the key objective is to compare the mechanical changes in tonic force by longitudinal smooth muscle after the addition of different concentrations of the drugs noradrenaline and acetylcholine. Peristalsis is the wave of muscle contractions that allow circular muscles to constrict the gut and longitudinal muscles to shorten it in an attempt to move the food bolus towards the rectum. A series of dilutions

Also‚ dissolve 0.16 g of hydrated calcium chloride (CaCl2.2H2O) and 0.39 g of hydrated magnesium sulfate (MgSO4.7H2O) in 100 mL of distilled water. Add the 100 mL cautiously to the 800 mL‚ stirring vigorously. Then make the final volume equal to 1 liter by adding more distilled water

Within the body‚ there are billions of cells that are essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured
