Cardiac muscle

The muscle has amazing cells structures in the body. Because every part of our body acts as a working machine all organs of the body are equally significant. The skeletal muscle in the body is a very important portion of the body. When people think of muscles, they usually think first of voluntary movement, but that is only part of the story. Muscles are literally everywhere in the body. Throughout the body, there are muscles in the eye, heart, limbs, tongue, throat,…

work. Some muscles are autonomous, or work by themselves, while others are controlled by the nervous system. Four tissues/organs of the muscular system are cardiac muscle, skeletal muscle, smooth muscle and the heart. Cardiac muscle is they type of muscle that makes up the heart and is autonomous. The heart is a muscle that is crucial to survival. Smooth muscle lines the inner digestive tract. It contracts to allow food to proceed down the digestive tract. This type of muscle is also…

are predominate for cardiac metabolic energy production meaning that these two substrates are the main energy providers when it comes to a healthy functioning heart. When a heart is healthy these two substrates are well balanced and are utilized to the fullest, but when this balance is thrown off it results in different cardiac diseases. These chronic cardiac diseases usually have one or the other substrate being utilized more. If glucose is utilized more it can lead to cardiac hypertrophy or…

system of the body that contains smooth, skeletal, and cardiac muscle tissue. This system contains a variety of functions including movement of the body and of materials throughout the body, maintenance of posture, and heat production. Muscles are the only tissue in the body that have the ability to contract and therefore move the other parts of the body. The muscular system is important because without it, life would completely stop. Muscles produce not only voluntary movements but involuntary…

Dogs to Humans Humans and dogs are similar in many different ways, one way is that they have similar muscular systems. We humans have some similar muscles as dogs like, gluteal muscle, biceps, latissimus dorsi, trapezius, deltoid, and the external oblique. The different muscles are used by dogs and humans in pretty much the same sense so they can run, walk, and jump. The dog’s muscular system is one of the biggest systems in their body. There are two important functions of the muscular system…

how different individuals respond to exercise, specifically how long they can work and how efficiently they work. We predicted that females who exercise will have a higher relative-VO2, higher a-vO2-difference, higher stroke volume(SV) and higher cardiac output(CO) at their peak work rate; than individuals who do not exercise. In addition, we predict that females who exercise their heart rate(HR) will be lower before and after exercise than in females who do not exercise. These subjects…

Duchene Muscular Dystrophy is an inherited neuromuscular disorder of childhood which primarily affects boys characterized by progressive muscle weakness and wasting due to a mutation in the dystrophin gene of X chromosome. Degeneration of muscles usually begins to appear in the lower half of the body then spreading into upper limbs and eventually leading to death. Between 1830 and 1850 scientists reported on an illness where boys grew gradually weaker, lost the ability to walk and died at an…

types of muscle. In regards to muscle, there are three main types. These include voluntary (skeletal) muscle, involuntary (smooth) muscle and cardiac muscle. Each have particular functions within the body. One of the main functions which skeletal muscle is responsible for is allowing movement including both fine and gross motor skills to be carried out. Another function which skeletal muscle is required for is protecting an individual’s organs. An important function which cardiac muscle is…

Questions: 1. In terms of muscle fibres, what long-term changes might occur due to the treadmill exercise? After 20 weeks of training, as treadmill exercises are generally aerobic and endurance related. During aerobic exercise the muscle is extracting oxygen from the blood supply to feed the muscles with sufficient energy, over a 20 week period the capacity of capillaries may have adapted and increased so that…

) . PENETRATING CARDIAC TRAUMA Penetrating trauma is the most common cause of significant cardiac injury seen in the hospital setting, with the predominant injury being from guns and knives. Penetrating cardiac trauma is secondary to stab wounds in 35 to 96 percent of patients…
