Muscles, we all have them in our bodies. We use them voluntarily and involuntarily. Some people choose to emphasize their muscles’ appearance more than others but this doesn’t mean their purpose has changed. We have three different types of muscles: Cardiac Muscles, Smooth Muscles, and Skeletal Muscles. All these types of muscles perform different tasks in different locations, but are guaranteed to make our daily lives easier. Why muscles? Because as an athlete you learn how important our muscles
You can only imagine how many people buy apple cider vinegar to use in recipes and on their salad while never realizing the variety of possible health benefits they might be receiving. The reality is that apple cider vinegar or ACV has been used for thousands of years as a home grown remedy for a variety of health issues. The possible health benefits range from weight loss to improving a person's circulatory or digestive system functioning. Given that improvement with the circulatory system us frequently
Skeletal muscles are tightly bound together compared to cardiac muscles , whereas cardiac muscles are shorter than those of a skeletal muscle. Endomysium and mitochondria within cardiac muscles is denser than in skeletal muscles, the skeletal tissue experiences fatigue if they have to contract for a long time yet the cardiac muscle never does. The skeletal muscles contain two types of fibres and the type of fibre present is dependant upon what kind of exercise you do, red fibres contain mitochondria
Cardiac VS Skeletal Muscle Where are they found in the body? Cardiac muscle is found only in the heart and skeletal muscle is attached to bones which forms the skeleton to be used for movement. What is the structure? Cardiac and skeletal muscle is both striated (striped). Skeletal muscle tissue is composed of individual muscle cells known as muscle fibres or myocytes, within each myocyte there is myofibrils which help in muscle contraction. Skeletal muscle is made up is long and cylindrical in shape
allow the blood to be successfully pumped to all of the cells, organs and tissues. This is called systolic and diastolic pressure. Systolic is the heart contracting and diastolic is the heart at rest. The heart pumps by electrical impulses from cardiac muscle fibers. There are four sources for the heartbeat, they include the Sinoatrial node also known as the pacemaker, the Atrioventricular Node, bundle of His, and purkinje fibers. The impulses start at the SA node then spreads through the heart repeatedly
Skeletal muscle proliferation and differentiation are closely coordinated and highly regulated processes. It is marked by quite an impressive change in gene expression in terms of amplitude of the expression and the number of the genes being regulated simultaneously. For instance, hundreds of cell cycle effector genes go from highly expressed to permanently silenced as myoblasts differentiate into myotubes [12]. Cell cycle progression (proliferation), arrest/withdrawal and differentiation are three
In this study, three volunteered subjects with the same age (19) and different in body weight (43, 50, and 85 kg) were challenged to obtain the skeletal muscle biomechanics data by measuring moment force from maximum weight that the subject can hold on certain angles (20o, 45o, 60o, 90o, and 120o), moment arm, and resistance arm during muscle contraction. The result shows that the average maximum of weight that each subject can hold for certain angles varies. The weight was increased from 20o to
There are 6 important Systems in the human body,this contains of the digestive,musculoskeletal,respiratory, nervous and circulatory system.They help us with our everyday life without them we would not be able to survive. The digestive system helps us digest our food and provides us with energy and nutrients.Musculoskeletal helps us with our movement without it we wouldn’t be able to stand,run,walk or sit. The respiratory system brings oxygen for us so that we can breathe out CO2. The Nervous system
heart should get change.This study was performed in order to look at the effect posture has on heart rate and blood pressure. Hypotenuse: I predict that the change in body posture will affect the heart rate. I believe that the position where your muscle are working the most will increase the heart rate and the position where the heart must pump against the force of gravity will put the heart in the toughest situation. For these reason I predict that it will be position 1 that will get the highest
The specialised cardiac tissue works with nerve tissue and blood tissue to make up the organ, the heart. The cardiac tissue is specialised to contract by initiating impulses making the heart beat, the nervous tissue found in heart receives messages from the brain telling the heart to beat faster or slower and the blood tissue is specialised to carry blood from the heart to the rest of the body. The heart organ makes up the cardiovascular system. The cardiovascular system works together with other
