Myosin

and humans .They make up our muscles which support our body integrity and can contract and relax depending on the movements that our body is making .They are composed by muscle fibers and many microfilaments which are made of two proteins called myosin and actin which make possible the contraction of muscles .Therefore the muscle tissue have striations which allows the muscle tissue to enlarge and shrink while we are making movements . Their nuclei instead are located on the edge and…

difference between the muscle and nervous tissues related to the organelle present and its function is that the proteins which are in the nucleus of the tissues are different and have different functions. In the muscle tissue the proteins, actin and myosin are required for muscle contraction. However in the nervous tissue to maintain the ‘resting potential’ carrier proteins are needed. The difference between the function and location of the muscle and nervous tissues is that the function of the…

(Martini & Nath,2014 p.689-692). Each cardiac muscle fiber is made up of a single nucleus that has the appearance of striated or striped. The appearance is light and dark bands. Dark bands are made up of thick protein filaments that are produced by myosin proteins. These bands do not let light pass through. The light bands are between the dark bands, they are made up of actin protein and let light pass through them (Martini & Nath,2014…

20 people out of every 100,000 people worldwide have Myasthenia Gravis (Myasthenia Gravis, 2012). Myasthenia Gravis is a disorder that causes skeletal muscle weakness. People experience the worst weakness during periods of activity and the weakness improves under periods of rest. The most common weakness is located in the muscles around the eyes. This causes blurred or double vision in the eyes. It also effects the muscles used in facial expression and chewing. These conditions can cause…

the cytokinesis processes occurs through cleavage. Firstly, in the old metaphase plate position, a cleavage furrow is formed. On each sides of the furrow, a contractile ring formed of actin microfilaments. These actin microfilaments interact with myosin protein, which causes the contraction of the ring. This contraction is acting on pulling the rings so the furrow goes deeply until separating the cell into two cells. In plants, cytokinesis…

RESULTS Lipid Extraction The prediction made was that adipose tissue most likely had the highest lipid content and skeletal muscle had the lowest lipid content when comparing liver, muscle, and adipose tissue. The percent lipid was found to be 30% in liver tissue, 70% in muscle tissue, and 90% in adipose tissue in the samples collected. Protein Extraction and Quantification The absorbance vs concentration curve prepared from the Bradford Protein Assay standards was found to have a linear…

Muscular System The human body is composed of 640 to 850 muscles each having a different function in helping the muscular system operate. The main function of the muscular system is movement. Muscles help provide strength, endurance, and help to keep the body warm. Muscles help keep the body warm by continuously pumping blood out of the heart and by body movement. There are three main categories of muscles in the human body: skeletal, cardiac, and smooth (non-striated) muscles. One…

Bernhardt (2004) states that speed endurance is the ability to maintain a very high speed for long periods of time. Masters Athlete (2015) agrees with this and adds that recovery between sprints isn’t long enough to recover all required energy for high levels of speed endurance. Bernhardt (2004) stated that as intensity increases and duration continues, it becomes increasingly difficult for the body to provide enough oxygen so the anaerobic lactic system begins to contribute more energy to fuel…

Hypertrophic cardiomyopathy (HCM) is the most common form of feline cardiomyopathies. This disease affects the cardiovascular system. The heart has many important anatomical features. One of these being the ventricle of the heart. The ventricle of the heart is the main heart muscle that pumps blood. When HCM occurs the left ventricle within the heart thickens. When the thickening of the ventricle occurs there will be a decreased ventricular chamber volume, and abnormal ventricular relaxation.…

1. Why is the cell theory significant (don’t just state the tenets, explain what it means and why it is a theory)? The cell theory is significant because of it’s three basic ideals or principles. The first is that all organisms are made from cells. This means that cells are the building blocks of life and technically, all of life is connected and related to each other by this tenet. In addition, by researching and examine one type of cell, the results can be assumed for all similar types of…
