Regulatory Behavior Monica Rhodes PSY 340 Biological Foundations of Psychology September 22, 2014 Dr. Teralyn Sell Abstract The nervous system is a vital part of our body. Without the nervous system our body would have no control over it functions and how to perform properly. Each component must work together to achieve each task no matter how big or small the task is. Just think about it for a second, the smallest movement requires the use of muscles, bones, and neurons which pass…

1. Auscultation method provides a closer to true value systolic blood pressure (SBP). Despite the existence of a potential auscultatory gap, where an underestimation of SBP can occur, crosschecking with the palpation method can eliminate this potential error. The palpation method as well is also subjected to many sources of error, such as strength of the pulse, location etc., and it requires the cuff to be more deflated, giving a lower systolic pressure reading, making it only a good estimate.…

Q1: Pt is diagnosed with ST elevation myocardial infarction (STEMI) which normally occurs due to antheroscheloric plaque rupturing and distributing in the blood vessall. Substances that promote platelet aggregation and thrombus formation are then exposed in the blood streams which will eventually cause blockage of blood flow in the coronary artery . Patient’s medical history of hypertension is one of the most important risk factors of acute Myocardial infarction as the constantly high blood…

Smoking has a large effect on all systems of the body. W.R, a 48 year old plumber has a 36- pack year smoking history. One of the major effects of smoking is atherosclerosis. Atherosclerosis is the hardening and narrowing of the blood vessels due to a fat and plaque buildup on the vessels. Some of the major risk factors for atherosclerosis include hypercholesterolemia, increasing age, sex- male being more prevalent than females, high blood cholesterol levels, cigarette smoking, obesity, and…

1. Distinguish between afferent and efferent nerves. Afferent nerves are the sensory nerves. They carry information from the world to the brain and spinal cord. Efferent nerves are the motor nerves they carry information out of the brain and spinal cord to other parts of the body. Afferent nerves take in information and efferent nerves carry out information. 2. Study Figure 2.1. What makes up the Central Nervous System (CNS)? The central nervous system is made up of the brain and…

TAQ 1 Explain the term Homeostasis. The term homeostasis is derived from two Greek words; homios meaning ‘the same’ and stasis meaning ‘steady’. It refers to the processes by which the body and internal cells seek to constantly maintain an internal state of balance and equilibrium even when faced with external environmental changes. This is achieved through either positive or negative feedback loop controls associated mainly with the endocrine and nervous systems. Principal homeostatic…

of the thyroid. This type has a lower cure rate than papillary and follicular and it can be associated with other endocrine tumors. It is more common in females than in males. It spreads to lymph nodes early and distant organs (liver, bone and adrenal medulla) late. Certain genetic syndromes can increase the risk of medullary thyroid…

the parasympathetic nerves. While postganglionic sympathetic nerves are present, they do not transmit norepinephrine directly to the smooth muscle—the norepinephrine that is available is circulating freely among the tissue, secreted from the adrenal medulla…

Jones. Mr. Jones appeared to be in distressed. He is now using his accessory muscles to breathe, crackles are heard on auscultation and there is decreased air entry in the left and right bases. Chest X ray revealed consolidation on the left lower lobe and atelectasis in the right lower lobe. After a series of investigation in the emergency department, Mr. Jones was commenced on Normal Saline at 125 mls/hr and he was given oxygen via non rebreather mask at 10L/min. He was then transferred…
