by a T wave; in Atrial Fibrillation, the Sinoatrial node fires irregularly causing there to be no clear P wave and an irregular QRS complex (Ignatavicius & Workman, 2013). Basically, it means that the atria, the upper chambers of the heart, are contracting too quickly and no clear P wave is identified because of this ‘fibrillation’ (Ignatavicius & Workman, 2013). Clinical Manifestations and Pathophysiology A normal heart rhythm begins at the sinoatrial node and follows the hearts conduction pathway
References and resources used: Date reviewed: Sinus Tachycardia Sinus tachycardia is a kind of fast heartbeat. In sinus tachycardia, the heart beats more than 100 times a minute. Sinus tachycardia starts in a part of the heart called the sinus node. Sinus tachycardia may be harmless, or it may be a sign of a serious condition. CAUSES This condition may be caused by: • Exercise or exertion. • A fever. • Pain. • An injury. •
Commotio cordis occurs after a blunt, non-penetrating blow to the precordial area of the chest wall that results in the induction of an often fatal ventricular fibrillation in a heart that does not have a preexisting structural or electrophysiological cardiovascular disease (Yabek, 2011). The blow is often perceived to be irrelevant, yet can cause a debilitating injury or even death. Death may be sudden or after a brief period of lucidity with purposeful movement prior to collapse (Yabek, 2011).
Uterine cancer is an important women health problem developing rapidly, killing over 200,000 women each year. No one has discovered the actual cause, but there is a leading factor that has great suspicions to what is causing this cancer to grow rapidly. The history of endometrial cancer is very vague, but there are a lot of factors and facts from previous patients that need to be concerned. From the sources that I have research, there was not a definite name that individuals could say discovered
Although there is little news of it today, Diphtheria was one of the most common diseases found in the Eastern Region especially in Europe. Known as the “Strangling angel of children” it caused the death of many children by suffocation in Europe during the 17th century. Although today it is very rare to find this disease in the United States, this disease is commonly found in places where there is low hygiene or an unclean environment. Due to the modern understanding of the transmission and composition
the lymph nodes or vessels causing improper drainage of lymph fluid. Primary lymphedema is inherited as an autosomal dominant trait that is a very rare condition. It is caused by deformity or immaturity of multiple lymphatic vessels. This condition is further divided into three disorders depending on the age of onset; congenital lymphedema, which begins at infancy, causes abnormally
problem is an bigger issue in sensor field. Each and every sensor nodes are needed to transmit the node, then only the data’s are reached to base station, so each and every sensor node within a group need an keys to transmit the data. While attacker entered and also get the full access of sensor node, and ready to hack data, but they need to wait. Because the node are none of the keys at the time, transmitting time only the nodes get access of keys from the cluster head. A cluster having a variety

arising from the lymph nodes or other sites of lymphoid tissue are broadly termed lymphomas. This group of diseases is divided into Hodgkin’s disease and non-Hodgkin’s lymphoma. In both conditions, there is a replacement of normal lymphatic tissue by collections of abnormal lymphoma cells. The lymphatic system are a complex network of specialised cells and organs that defend the body against infection. Lymphatic organs include the bone marrow, spleen, thymus gland, lymph nodes, tonsils, adenoids,
Definition Malignant melanoma is a type of cancer arising from the melanocyte cells of the skin. The melanocytes are cells in the skin that produce the pigment melanin. Malignant melanoma develops when the melanocytes no longer respond to normal control mechanisms of cellular growth and are capable of invasion locally or spread to other organs in the body (metastasis), where again they invade and compromise the function of that organ. Description Melanocytes, embryologically derived from
Background Agricultural methodology and process has been improved and benefitted with new technologies. Precision Agriculture (PA) definition is evolving with technology development. Most precise definition may be “The application of technologies and agronomic principles to manage spatial and temporal variability associated with all aspects of agricultural production for the purpose of improving crop performance and environmental quality”[1]. PA is conceptualized by a system approach to re-organize
doesn’t cause your Dendritic cell (DC) to have a loss in function, however, it will initiate in your immune system. When you are infected the HPS it induces your DC to maturation then uses the DC to serve as a vehicle to migrate to the regional lymph nodes once the infected DC reach this area the immune response will be to release virus-specific antibodies and T cells according to Kruger D., Schonrich G., Klempa B.
Lymphatic System Overview A well-functioning lymphatic system is essential to maintaining good health. The lymphatic system consists of a network of lymph vessels, lymph nodes, lymph ducts, and organs that can be likened to a drainage system in the body. Lymph Drainage Function The lymphatic system’s main task is transporting lymph consisting of…. Lymph helps cleanse the body of waste, toxins, and other foreign particles, such as infectious microorganisms. Lymph is formed from interstitial fluid
throughout the lymph nodes in the body. The cause of Hodgkin’s lymphoma is unknown, and it is sometimes found by chance. This disease is typically treated with chemotherapy and radiation and, if found in the early stages, the patient has a good chance of being fully cured. According to Taber’s Cyclopedic Medical Dictionary (2013), Hodgkin’s lymphoma is “a malignant lymphoma whose pathological hallmark is the Reed-Sternberg (RS) cell. This lymphoma typically begins in a single lymph node (esp. in the neck
Lymphadenopathy is the term for swelling of the lymph nodes. These are the bean-shaped organs found in the underarm, groin, neck, chest, and abdomen. They act as filters for the lymph fluid as it circulates through the body. The most common site of lymphadenopathy are the cervical lymph nodes found in the neck. The lymphatic system is part of the immune system and functions to fight infections and disease. As infection-fighting cells and fluid build up, the lymph nodes enlarge to many times their normal size.
without recognizable malignant cells. It shows as isolated masses of lymphoid tissue and lymph node hyperplasia, usually in the abdominal or mediastinal area. There are two types of the disorder, the first one is the hyaline vascular Unicentric Castleman’s disease type that is a localized form affecting only a single gland (lymph node) in the lymphatic system (asymptomatic) or may
Lymphoma is described as the cancer of one or more lymph nodes. There are multiple types of lymphoma, with multicentric lymphoma being the most common. There are several stages of this condition that all affect how the animal will be treated. There are multiple breeds that are predisposed, such as boxers and basset hounds being the most common. Cats who have been exposed to FeLV, or FIP are most at risk for lymphoma. Animals of either species who have been exposed to cigarette smoke are at risk
The Lymphatic System The Lymphatic System consists of tissues and organs such as the tonsils, thymus, lymph nodes, lymph glands, lymphatic vessels, spleen, Peyer’s Patches (found in the small intestine), appendix, bone marrow and lymph. These are the states of the lymphatic system when it is in a healthy state. The lymphatic system works with the immune system in providing the body protection from harmful diseases and infections. The lymphatic system regulates interstitial fluid protein. Its function
What is Lymphedema? Lymphedema is an abnormal collection of lymphatic fluid and swelling caused by several removal, obstruction, and damage to the lymph nodes which is part of the cancer. The Majority of the swelling happen in the arm or legs may occur in any other body parts. Lymphedema disease can be developed when a lymph vessel is damaged or clogged. Usually the lymph liquid is carried out the body system by a lymph vessel. Although the protein rich fluid is collects in certain areas, they
ones to look at with the lymphatic system is epithelial tissue. The epithelial tissues have many functions but the ones that affects the lymphatic system are diffusion and cleaning. Organ The organs that make up the lymphatic system are the lymph nodes – small, oval or bean shaped and mainly found in the inguinal (groin), axillary (armpit) and mammary gland areas, the thymus – a bilobed organ located in the upper chest region between the lungs, posterior to the sternum and the spleen – which measures
