Cardiac muscle

exercising is because they may have limited mobility. Because of their age seniors need approach everything differently in life and exercising is no different. After the age of 30 muscle mass will start to decrease. As for seniors, the body fat can double from when they were younger. If a senior citizen wants the put-on muscle mass than they need to take similar steps that a young…

explaining how she was able to increase her oxygen consumption levels by increasing her cardiac output, and increasing her arterio-venous difference or in other words is the difference in oxygen saturation of the blood going to the tissues and of the blood returning to the heart. First, your maximum VO2 is the greatest amount of oxygen you can utilize, and is a value that can be influenced…

how to administer the possibly life saving measure. All high schools should require a cpr course to be taking in order to graduate because Cpr saves lives, most cardiac arrest situations occur at home, and so they should be able to tell the difference between cardiac arrest and a heart attack. About 900 americans die everyday due to cardiac arrest According to the new york times. when you know how to perform Cpr you might be saving a relative's life, loved ones, or even a stranger. One of the…

that increasing stimulus strength will increase the force generated by the gastrocnemius muscle and visa versa till 0.2V, where the force germinated starts to decrease. As shown in Table 2 and Figure 2, the strength of the stimulus started from 0.00 V to 1.00V with 0.05 V and 0.10V intervals. At 0.10V the force generated by the muscle increases rapidly from 0mN to 288.33mN. The force generated by the muscle continues to increase to 699.99mN at 0.15V until the stimulus strength reaches 0.2V.…

Muscles (Grip strength) In this week’s lab, we was doing an experiment on forearm, and its muscle fiber with nerves. The forearm is a part that between the primates’ elbow and wrist. Forearms contain connective tissue, nerve tissue and muscle tissue. In which, connective tissue is just radius and ulnar bones. However, there are a great deal of muscles and nerves in the forearm. When a nerve impulse transmission to synaptosomes induced depolarization, allows calcium ions to enter the cell…

undesirable plane, another purpose they serve is that they limit the range or extent of normal movement (Wallace 2013). Unlike ligaments where the bone might be attached to another, tendons are fibrous tissue connecting the bones to the surrounding muscle. With this in mind, there are three types of joints that are classified by how much movement they allow. The first type is known as immovable joints, this involves two or more bones being fused together (Wallace 2013). A…

within the body so that any small forces can be used to help the bigger forces which are needed. The muscle and bones come together to make a lever, this helps to turn a pivot joint also known as mechanic advantage. There are 4 areas of a lever such as the bone on our bones turn to lever arms, the joints turn to pivots, the muscles stimulate effort to move the force or load and the body parts give muscles strength to move what needs lifted. 1st class levers are very uncommon within the human…

Muscle contraction is a process leading to the shortening and or development of tension in muscle tissue. Tension is developed in muscle tissue when muscles contract. That tension may or may not lead to movement. To contract means to shorten; however, this is not always the case in a muscle contraction. The tension may cause muscle to remain the same, elongate, or condense. When muscles decrease in length (e.x. lifting weights) it is called a concentric contraction. When muscles increase in…

extensively used to identify and observe the muscle disease. It is present in higher concentration in serum in reply to muscle insult and is the most delicate sign of muscle injury, which gives a precise estimate of progression of muscle injury (Bohlmeyer TJ et al.1994).It is found mainly in the myofibrils, mitochondrial membrane and the muscle cytoplasm (Bessman SP and Carpenter CL, 1985). CK is a dimer molecule, and composed of two subunits, CK-M (muscle type) and CK-B (brain type) and has…

Exercise is physical movement accomplished through the contraction of skeletal muscles. These contractions require significant amounts of energy and constitute a major physiological function. The energy for contractions is provided by ATP which can be synthesized from many different substrates.K The metabolic demands of skeletal muscle incurred through brief and acute exercise and be fulfilled through hydrolysis of creatine phosphate which provides energy to synthesize ATP from ADP. For longer…
