Beating Heart

The definition of the term is as follows. General adaptation syndrome (GAS) is the predictable way the body responses to stress as described by Hans Selye (1907-1982). The three phases are Alarm Reaction, Resistance and Exhaustion. 1. Alarm Reaction The first stage of the general adaptation stage, the alarm reaction, is the immediate reaction to a stressor. What is stressor? Any urge, force, or pressure (that is, deleterious force) brought to bear on a person, bodily system, or governmental…

REASON CHIEF COMPLAINT: Heart failure. Coronary artery disease. Atrial flutter. BLANKLINE This patient had an acute MI _____ and underwent three vessel coronary artery bypass grafting at that time. He states he had a cardiac catheterization elsewhere about four years ago and they did not perform any intervention at that time. He has had a transthoracic echocardiography and stress nuclear imaging test that has shown EF of 40%. His last nuclear imaging test showed only mild inferior…

The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The rotator cuff is a group of muscles and their tendons that act to stabilize the shoulder. The four muscles of the rotator cuff are over half of the seven scapulohumeral muscles. The four muscles are the supraspinatus muscle, the infraspinatus muscle, teres minor muscle, and the subscapularis muscle. The…

To estimate time of death, we can first narrow down the window on the timeline by looking at the stages of rigor mortis and lividity. At the autopsy, it was observed that the victim was in full rigor mortis. The human body is typically in full rigor, or stiffness of the muscles, between 8 to 24 hours after death, during which time the muscles become completely stiff and stay stiff before rigor mortis dissipates (Crowe, n.d.). In this case, it may have been affected in that this process might…

Stress can be defined in 3part, which are stressor, stress and stress response. According to psychology glossary “A Stressor is anything (physical or psychological) that produces stress (negative or positive) is considered a stressor. For example, getting a promotion is a positive event, but may also produce a great deal of stress with all the new responsibilities, workload, etc.” (2015) By definition, stress is any uncomfortable "emotional experience accompanied by predictable biochemical,…

The skeletal muscles are connected to the skeletal system. These muscles are controlled voluntarily by a dog when the dog runs, eats, walk, or plays. Just like smooth muscle this is in the humans for the same reason. The cardiac muscle is in the heart and is an involuntary muscle but is striated just like the skeletal muscles. Humans also have the cardiac muscle which, of course, is involuntary. The supraspinatus, infraspinatus, pectoral, trapezius, biceps brachii, brachialis, and triceps…

Muscle tissue is one of the four tissues types that exist in the human body. There are three different muscle tissues, skeletal, cardiac, and smooth. Skeletal muscle tissue cells are long, striated, and have many nuclei. Cardiac muscle tissue, just like the skeletal is also in striations. These cells are short and branched. Unlike, the skeletal muscle tissue these cells die single nucleated. They are connected by intercalated discs. Smooth muscle tissue is not striated. Its Cells are short and…

Hypokalemia Hypokalemia means that the amount of potassium in the blood is lower than normal. Potassium is a chemical that helps regulate the amount of fluid in the body (electrolyte). It also stimulates muscle tightening (contraction) and helps nerves work properly. Normally, most of the body’s potassium is inside of cells, and only a very small amount is in the blood. Because the amount in the blood is so small, minor changes to potassium levels in the blood can be life-threatening. CAUSES…

A tendon is tissue that attaches muscle to over the counter bone. it's miles flexible, hard and fibrous and it can withstand tension. A ligament extends from bone to bone at a joint, whileover the counter a tendon extends from muscle to bone. Tendons and muscle mass work over the counter and exert a pulling force. Tendons and ligaments are tough and fibrous, however over-the-countery may be called tender tissue, due to overover the counter overover the counter smooth compared with bone. If…

Pathologic heart murmurs are the number one birth defect in infants. It affects 36,000 infants in the United States. Many children can die from it, but many children can also survive it. Infants can be born with it, and they can also develop the disease as they grow older, in this essay, we will explain to you the causes of heart murmurs, the treatment of heart murmurs, and the symptoms of heart murmurs. Pay attention, because your son can be born with this. Causes of heart murmurs Pathologic…
