Cardiac muscle

Some of the physical signs of this state include a higher heart rate and increased muscular tension (Insel and Roth 2013). Another factor that lead to the conception of this hypothesis, is the fact that oxygen is carried to the muscles via the blood stream and the muscles need more oxygen when they are being used for exercise, this is what causes faster breathing during aerobic exercise. Before this experiment was conducted, there was a chance that the initial hypothesis was incorrect and…

Contrast baths are offered to athletes and use the method of alternating vasoconstriction and vasodilation in an attempt to relieve symptoms after strenuous exercise (Bieuzen, Bleakley, & Costello, 2013). The therapeutic goal of using contrast baths is to increase blood flow and bring more nutrients to the site of the injury. By alternating cold and hot water immersion a pumping mechanism is created and this promotes soft tissue healing (Shih, Lee, Lee, Huang, & Wu, 2012). Summary In this…

this gene in myocardial tissue is SERCA2a, and it is responsible for removing around 75% of the Ca2+ ions from the cytosol of muscle cells in the heart. SERCA2a acts like a pump that sits on the edge of the sarcoplasmic reticulum and protrudes out into the cytoplasm of the cell (Hajjar & Njeim, 2010). The sarcoplasmic reticulum (SR) is an organelle that is unique to muscle cells. Its primary purpose is the storage, release, and reuptake of Ca2+ ions from the cell’s cytosol, and this in turn…

that can change depending on how the kettlebell is held and moved. The overall purpose of the free weight is to offer a dynamic training of the body to improve overall strength, increase mobility, and cardio endurance while integrating all areas of muscle. The two major components of the kettlebell are the handle and the…

right atrium that sends rhythmic electrical impulses to relax and contract the muscles.” (Lerner and Lerner, 2014). If the does not work and you have a irregular heartbeat you may need a pacemaker. This will help control the irregular heartbeats with low energy shocks to the SA node or…

sarcoidosis is cardiac involvement that ranges from asymptomatic conduction abnormalities to fatal ventricular arrhythmias, with clinical manifestation of the disease being present in only 2% to 7% of all diagnoses [2, 3]. Though conduction abnormalities are the most common…

when called upon. This system is used in anything lasting from over ten seconds, all the way up to one minute, and produces a by product called lactic acid. Lactic acid is the feeling you get in your muscles like a “burning” sensation, and can lessen ones ability to exercise or do work with that muscle. Glycolysis is a system that would be used when running longer sprints such as the 400 meter, when the runner must pace themselves and be as efficient and quick as possible. Finally, the third…

Fibromyalgia disease is found in the muscle system and was once thought to be a mental disorder. In the early 1800s it was first described by doctors, the symptoms were stiffness, aches, pains, tiredness, and difficulty sleeping. In the early 1820s a Scotland doctor described the tender points if fibromyalgia. In 1976, the name was changed to fibromyalgia because the swelling wasn’t causing the pain in the body. Duchenne muscular dystrophy is another disease found in the muscle system. In the…

Changes in Tissue Homeostasis of the Elderly That Result in Altered Cognitive; Motor Abilities. As we age, homeostasis is harder to achieve within all of our cells. The cardiac muscle tissue and the walls of the blood vessels thicken, decreasing the amount of oxygen and nutrients that is pumped out to the entire body. The thickness of the blood vessels makes it hard for nutrients to enter the other tissues body, and for wastes to leave these tissues. Water is also harder to retain…

This single critical condition has claimed the lives of 287,000 people each year everywhere from the age of an infant to the age of your current peers to the age of the elderly (Heart Failure Statistics, 2016) . There are about 5.1 million people in the United States alone that suffer from this serious, possibly fatal, condition and die within five years of diagnosis (Heart Failure Fact Sheet, 2015). Not to mention, 1.4 million people under the age of 60 years old have this condition, and as a…
