The Impact Arthritis has on Anatomy and Physiology and the Implications this has on Provision of Social Care. There are around 16 million people effected by musculoskeletal conditions in the UK with 10 million of those suffering with arthritis (British Society for Rheumatology 2013). Arthritis is very common condition which mainly effects the joints in the body, causing pain and inflammation (Clough, 2006) however, arthritis can also effect other systems in the body, This assignment seeks to…

Introduction: The heart rate of an animal can be used as an indicator to identify when a stimulus evokes a reaction from the animal. Specifically in the case of humans’, there tends to be the cognitive ability to physically withhold a reaction from a stimulus and mask the involuntary reaction. However, the heart rate reacts immediately after a stimulus, and is not reigned in or controlled cognitively, so could the heart potentially be a true indicator of an individuals reaction to a stimulus?…

Jennifer Datus Anatomy and Physiology II Essay Questions Test 2 Professor Vernet 1. The beginning of the cardiac cycle starts with deoxygenated blood from the systemic circulation entering the heart into the right atrium from the superior and inferior vena cava. A chamber of the heart beats because of the electrical impulses located around areas of the heart that travel across the heart which allows the muscles to contract.The SA node located in the right atrium is also known as the pacemaker…

Epidemiology of RA: Various population-based studies shows that rheumatoid arthritis affects 0•5–1•0% of adults in developed countries. The disease is more frequent in women than men. Prevalence rises with age and is highest in women older than 65 years, suggesting hormonal factors could have a pathogenic role.40 Estimates of the frequency of rheumatoid arthritis vary depending on the methods used to ascertain its presence. Incidence ranges from 5 to 50 per 100 000 adults in developed countries…

1. Point A is considered the S1 area of the graph. At this point in the graph is where the sound “lubb” is heard. At this point is when the AV closes and the semilunar valve closes. 2. Point D is at the S2 area. This is where the “dub” sound is made. This is the beginning of ventricular filling where the AV valves open. 3. At the end of the atrial systole, the ventricles have a maximum amount of blood that each can carry. The quantity of this is known as the end- diastolic volume. 4. In S2 is…

Normal Anatomy and Physiology Blood is one of the components that make up the circulatory system in the human body. Blood functions as a transport system for oxygen and nutrients with other systems dependent on it for oxygen perfusion and removal of waste materials. Blood has different components predominantly red blood cells (RBC also known as erythrocytes, “are the largest portion of blood cells” ranging between “4,200,000 – 6,100,000/mm3” and depended on age and gender in the body of a…

Exercise Physiology It has long been thought that strenuous or prolonged exercise can affect the human’s endocrine system. This is an interesting scenario because endocrine system synthase performs as a negative feedback system. This means that when there is an unusually high level of a hormone in the blood, a signal will be sent back and production of that particular hormone will be stopped. The negative feedback system can easily keep all hormones levels at the optimal level for humans.…

Whether you are sitting at a desk doing a physiology lab report, or playing a sport in the park, you are constantly using muscles to accomplish those tasks. The fingers that are used to type the lab report rely on individual myofibrils to contract and cause movement. However, this mechanism occurs on a microscopic level, and predominantly in the myofibers. When a motor neuron experiences an action potential it releases acetylcholine to the motor-end plate which binds to a receptor on the…

Anatomy & Physiology Anatomy is the study of the structure and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. Aims and Objectives  The composition of bone  The structure of a long bone  Classifying the types of joint found in the body  Description of synovial joint  How joint operates  How two different systems communicate for normal functioning of a joint  Description of a disease involving the musculoskeletal system …

Almost all multicellular organisms contain a nervous system, which allows them to sense changes in their environment or induce muscle contractions through electrical impulses. The majority of nerves cells that make up the nervous system are excitable cells, as they have the ability to produce an electric current to formrom an action potential from using a concentration gradient of ions across their membrane (Sherwood, 2013). The current generated by the flow of sodium (〖Na〗^+) and potassium (…
