Common carotid artery Essays

minutes before finally being killed. The autopsy report for Nicole Brown states that “The incised wound of the neck is gaping and exposes the larynx and cervical vertebral column” and “On the left side the left common carotid artery is transected with hemorrhage in the surrounding carotid sheath and the left internal jugular vein is subtotally transected with only a thin strand of tissue remaining posteriorly with surrounding soft tissue hemorrhage”(Nicole) show that Nicole was not murdered in a

allow for a litter of 8 to 10 pigs. In fetal pigs, “the brachiocephalic artery splits into the right subclavian artery and the bicarotid trunk which then splits into the right and left common carotid arteries” (“Human/ Pig Comparisons”). Nonetheless, humans do not have a “bicarotid trunk and instead the left common carotid artery branches directly from the aorta” (“Human/ Pig Comparisons”). Fetal pigs also do not have iliac arteries that humans have. Additionally, because of the fact that pigs are quadrupedal

Aortic arches are also called as pharyngeal arteries. They are vascular structures that emerge from the ventricle of the heart. There are 6 pairs of these arches in embryonic stages which give rise to several major arteries later. They arise from the aortic sac and are present on the ventral and dorsal aorta. As discussed earlier that there are 6 pairs of aortic arches present in embryonic stages giving rise to several arteries are as follows: Arch 1st and 2nd: The first and second arches

modality is the most accurate in vertebral artery dissection diagnosis? Pei Wen Tammy Kwa, Sarah Moore, Paul Ryan, Kate Somers Introduction An arterial dissection is said to occur when the structural integrity of an arterial wall is compromised, permitting blood to collect between layers of the vessel wall to form an intramural haematoma. Arterial dissection is a common cause of stroke in the young, although it may occur at any age. Vertebral artery dissection (VAD) most often occurs in the cervical

presented with hoarseness due to vocal cord paralysis secondary to cardiovascular pathology is an extremely rare entity, better known as cardiovocal syndrome or Ortner's syndrome. The common underlying pathology was described as an enlargement of the left atrium or recurrent laryngeal nerve compression by the pulmonary artery. We report a case of undiagnosed congenital heart disease in a young lady presented to the ear, nose and throat(ENT) clinic for hoarseness and the management of the patient. Even

The human heart pumps blood through the arteries, which connect to smaller arterioles and then smaller capillaries. In this assignment, we will discuss the arterial blood pressure from several aspects, include definition, normal values for blood pressure, the most important factors affecting it, the mechanism involved in arterial blood pressure regulation, and the relevance between the pressure and the eye.  Definition of blood pressure, it’s Normal value, and the factors that determine arterial

the heart is artery; vein is towards the heart). If they connect arteries and veins then they are called capillaries and if an organ is receiving or returning the blood then the organ’s name is a part of the blood vessel’s name. Circle of Willis is a looped network (anastomosis) of arteries at the base of the brain. Branches of the internal carotid arteries form the front of the circle and branches of the posterior cerebral arteries form the back of the circle, with smaller arteries, collectively

1. INTRODUCTION Cardiovascular disease is the leading cause of death in renal failure patients. The morbidity and mortality in patients with chronic kidney disease is high and the presence of chronic kidney disease worsens outcomes of cardiovascular disease. Cardiovascular disease often begins before end-stage renal disease and patients with reduced kidney function are more likely to die of cardiovascular disease than to develop end-stage renal disease. 40-50% of all deaths in the end-stage renal

2.4.4. Vascular disease (multi-infarct or post-stroke dementia) Vascular disease is the term which describes blood vessel disease. Three types of blood vessels: arteries, veins and lymphatics circulate the blood in the body but when the circulation of blood becomes disturbances in the brain function. This is second most common cause (10-20 %) of dementia (Jones & Román, 2004). Mainly, language problem, persons memory, other intellectual disabilities, impaired judgment, memory loss are the signs

Coronary Artery Disease is a condition that is caused by a thickening of the inside walls of the coronary arteries. It is disease is also known as CAD, Arteriosclerotic or Coronary Heart Disease. Coronary heart disease is one of the most common heart diseases in the United States. The risk of this disease increases with increased age. The coronary arteries are major blood vessels that supply our hearts with blood oxygen, and the nutrients we need to survive. An artery has a smooth inner lining

Question: What are the effects of temperature on heart rate and strength of contraction? The effects of temperature can either increase the heart rate or decrease the heart rate. The temperature can also effect the strength of contraction either by making the contraction stronger or weaker. Background: Explain on the cellular level how dropping warm Ringers solution on the frog’s heart would affect the cells of the SA node. Dropping warm Ringers solution on the frog’s heart would increase the heart

Pulmonary artery- transports deoxygenated blood away from the right side of the heart to the lungs (viii) Pulmonary vein- this is where oxygenated blood leaves the lungs and returns to the heart (ix) Aorta- passes blood from the left ventricle to the whole body The blood

Introduction Syringe Pump is another type of infusion pump which is small used to deliver small quantities of intravenous medications and fluids. It is also called as syringe driver. Most of the times this is used to infuse things and sometimes use to withdraw things.Actually we use syringe pumps applications where we need to deliver specific volume of fluid. We can use constant delivering rate or programmed flow rate. Most important part is exact deliver finite amount precisely because here we

dorsal and ventral components, for the dorsal and ventral musculatures. The sciatic nerve is formed when the large dorsal component of the sacral plexus(common peroneal nerve) and the ventral component (tibial nerve) move downward close together[2]. Hence, based on their previously mentioned developmental formation, it is possible that the common peroneal and the tibial divisions of the sciatic nerve separate from each other at different levels from their origins: within pelvis, in the gluteal region

Introduction: BLOOD PRESSURE (BP) is defined as the "pushing force exerted by the blood against the vessel walls". This pressure is highest in the arteries and lowest in the veins. As a result, the blood moves from the arteries through the organs into the veins and back into the heart to begin the cycle over again. The heart acts as a pump to create the high arterial pressures that keep the blood flowing. Because it is the "driving pressure" that pushes the blood through the organs, the ARTERIAL

The Human Body System AC 2.1. Explain the structure and function of at least 3 to 4 systems 1) The Circulatory System; This system transports blood, full of oxygen and nutrients to and from the heart, and all around the rest of the human body. At the same time it transports out carbon dioxide and other unwanted material such as harmful minerals, waste material resulting from cellular breakdown, nitrogenous waste in liquid form, and food additives.These are then taken to the liver where they get

' hernia abdominal is the leakage of a viscus - or a part of it - from the abdominal cavity where it is normally contained. The herniation makes its way through a preformed orifice or an area of weakness in the cladding wall. Abdominal herniaAbdominal hernia is therefore the expression of a progressive weakening of the muscular and fascial walls, which under physiological conditions should keep the bowels in its proper place . abdominal hernias are called external because the viscera, slipping between

containing cholesterol and lipids on the inner most layer of the walls of large and medium –sized arteries. (Herbert, 2014) Atherosclerosis is the buildup of a waxy plaque on the inside of artery, the arteries are blood vessels that carry blood from the heart through the body, and they are lined by a thin layer of cells called the endothelium. The endothelium works to keep the inside of arteries toned and smooth, which blood keeps flowing. (Zarbock, et al, 2008) There are two major types

Beta Blockers That are Used in Managing Heart Failure Heart failure occurs when the heart is not able to pump or fill with blood to reach the body needs, leading to decrease in pumping action and cardiac output. The body will sense the hypo-perfusion of vital organs then activate the compensatory mechanisms. First compensatory mechanism is cardiac compensation by increasing the heart rate, contractility, or myocardial hypertrophy and remodeling. Additionally, systemic compensation by increasing

intestine and reduces intestinal and pancreatic secretions. Due to these actions morphine present frequent and relevant gastro-intestinal side effects including constipation, ileus, and occasionally abdominal pain. Moreover, nausea and vomiting are also common side effects of morphine. The vomit mechanism is not well and completely understood; however, the interaction with μ receptors in the chemoreceptor trigger zone and the vomiting center in
