External carotid artery

Hello everyone, In this thread, I would like to discuss about stroke and Tizanidine, a pharmacological agent is to manage spasticity. Stroke transitioned from being the third to the fourth leading cause of death in the United States (Goodman & Fuller, 2015). Although the decline in mortality, it remains as the leading cause of long term disability (CDC, n.d.). Stroke is a focal vascular-induced injury of the brain. Disruption of blood supply may be caused either by an obstruction (called an…

the leucocytes fight the pathogens. The lymphatic vessels contain subclavian veins that are located on the sides of the neck allowing the lymph fluid to enter the circulatory system. Lymph is made when the interstitial fluid is collected. When an artery reaches the tissues it branches into arterioles and then into a capillary network. These link up with venules to carry blood back to the veins. At the arterial end of the capillary the blood is under high hydrostatic pressure which will push the…

To help diagnose macular degeneration, an ophthalmologist or optometrist will perform a comprehensive eye examination that may include the following tests. First and foremost, the doctor will use a special instrument to examine the back of your eye byputting drops in your eyes to dilate them. He or she will look for a mottled appearance consistsyellow deposits that caused by drusenthat form under the retina. People with macular degeneration often have many drusen which are made up of lipids, a…

Rheumatic heart disease is when the heart is damaged. It’s often damage to the valves of the heart. Rheumatic heart disease is a result of having rheumatic fever. It’s commonly seen in children in many developing countries around the world. To begin with, Rheumatic fever causes a person to have rheumatic heart disease. Rheumatic fever affects the connective tissues of the body, mostly the connective tissues of the heart, brain and the joints of the body. Rheumatic fever is associated with having…

may experience unexplained weight gain, swelling in the ankles, feet, legs, and difficulty breathing due to fluid build-up into the body’s tissues (Funk & Wagnalls, 2016). Risk factors The most common risk factors of heart failure include narrowed arteries (atherosclerosis) high blood pressure, heart disease, infection of the heart, and congenital heart defects (Funk & Wagnalls, 2016). Patients at high risk for heart failure may take risks to reduce the risk. Also, patients with diabetes and…

vein or the long saphenous vein. This vein runs from the inside of your ankle, up along the inside of your knee, and up to your groin. It returns blood from your leg to your heart. This vein is used to make a detour (bypass) around a blocked heart artery. EVH is done as part of heart surgery. Endoscopic surgery is surgery done using a thin telescope (endoscope) with a camera. The endoscope is inserted through a small incision. LET YOUR HEALTH CARE PROVIDER KNOW ABOUT: • Any allergies you…

which fibrinous plaques, called atheromas, develop within the walls of the arteries, impairing the flow of blood. High levels of low-density lipoprotein (LDL), a component of cholesterol, are a major contributor to the formation of atheromas. A myocardial infarction occurs when a plaque completely occludes a coronary artery, or when an emboli travels to the coronary artery. (VanMeter & Hubert, 2014). When a coronary artery becomes occluded, oxygenated blood cannot reach the surrounding cardiac…

Congestive Heart Failure (CHF) CDC says that it is lead cause of death for ages 65 years and up. It depends on how well your physical health is, when you do the basics of taking care of yourself as far as. The use of medications and how often you exercise can help with your health and risk for heart disease. When your ancestors are involved into genetics of heart disease as far as CHF is can also be very difficult from not getting it passed onto you. Congestive Heart Failure can be very…

Case Study 5 – AB As discussed in case 3, septic shock results from widespread inflammation and vasodilation in response to an infection. Norepinephrine is useful in septic shock because it increases afterload to maintain adequate tissue perfusion (De Becker et al., 2012). Dobutamine is an inotropic drug used in septic shock as it stimulates myocardial beta-adrenergic receptors thus increasing cardiac output by increasing contractility and heart rate (Dellinger et al., 2013; Enrico et al.,…

The renal artery supplies blood to the kidney. The human kidneys receive approximately 25% of the blood pumped. Blood enters the capillaries of the nephron through the afferent arteriole. It then flows through the glomerulus and into the efferent arteriole. The varying sizes of these arterioles help to create the hydrostatic pressure and to maintain consistency of glomerular capillary pressure and renal blood flow within the glomerulus Before returning to the renal vein, blood from the…
