Document Summary
Nervous system- complex network of interconnected nerve fibers which function to regulate many important bodily functions (response to and recovery from stress). Gives input to brain and spinal cord using sensory receptors. Motor nerve fibers provide output from brain or spinal cord to muscles and other organs which leads to voluntary/involuntary movement. Limbic system: plays important role in stress and emotional responses (border the midline of the brain). Amygdale and hippocampus are involved in detection of threat and in emotionally charged memories. Atherosclerosis : caused by deposits of cholesterol and other substances on arterial walls, form plaque and narrow arteries, reduces blood flow therefore it reduces nutrients which leads to tissue damage. Angina pectoris (chest pain that sometimes occurs because muscle tissue of heart must continue its activity without sufficient air or adequate removal of carbon dioxide/other waste. Myocardial infarction: most likely will happen when clot develops in coronary vessel and blocks blood flow to the heart (heart attack)
