Abstract The purpose of this experiment was to use the muscle tension and the electrical activity in the dominant and non-dominant forearm muscle‚ the flexor digitorum superficialis‚ to analyze the determinants of muscle tension and fatigue‚ and the reasons as to why differences may occur between the dominant and non-dominant arm. The generation of tension in a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject

It is really amazing to see what happened so far in this generation. Today‚ we have everything we ever wanted with the help of science and technology. Science and technology completely changed the way we function everyday. We have different kinds of drugs and medicine that saves a lot of people everyday. We have amazing electronics and devices that can do anything with your control. We also have media technology where we are connected to everyone around the world. When talking about the technology

by the nervous and endocrine systems Skeletal muscle tissue function of most is to move bones of the skeleton (are few that attach to other structures ex--the skin). Muscle tissue is striated b/c alternating light and dark protein bands (striations) are visible when tissue is closer examined. Muscle tissue action is voluntarily/activity can be controlled consciously. Cardiac muscle tissue found only in the heart—forms most of the heart wall. Muscle is striated (like skeletal)‚ and its action is

Mitosis Review 1. So why does cell division occur? Cell division occurs because an organisms such as plants‚ animals and such need to grow on a molecular level in order for them to continue thriving. For example‚ new cells are created with the intention of replacing old cells and tissues‚ with fresh and functioning ones... for most part. In humans and other organisms‚ organ cells‚ muscle cells‚ bone cells and such are constantly replace for growth and prolongation of proper function. Also‚ embryos

Great job once again on answering the question about how muscle action relates to the movement. I think maybe I took it to the extreme‚ I went on about agonist‚ synergist‚ and antagonist muscles. I wasn ’t sure if I should add the levers too. It appears as though you explained every type of muscle movement and gave an example of each. I went into flexion at the elbow and discussed that the agonist is the main muscle mover‚ the antagonist does the opposite‚ and the synergist is the helper. However

"This Side of Paradise‚" a semiautobiographical novel by Fitzgerald chronicle the life of the young Amory Blaine as he entered the World War I. The war devastated the youth of the 1920s and 1930s‚ where many felt that their morality vanished and found themselves losing hope in America. The novel portraits two significant time periods‚ the "Jazz Age" and "The Lost Generation". The Jazz Age took place in America during the 1920’s and considered as a cultural movement from which dance

Why does vandalism occur? Vandalism is everywhere‚ why do it? It is stupid and reckless‚ not to mention illegal! It occurs because of bad choices you as a person make‚ like who you surround yourself around and the friends you choose. Or because of the mood or mindset you are in. There are many reasons why vandalism occurs‚ but not many ways to putting it to a stop. Friends are not always your friends! Friends sometimes get you into sticky situations‚ but friends are not the one’s making your choices

Muscle contractions are due to the sliding-filament model where the filaments slide longitudinally past each other producing an overlap between thin and thick filaments. The sliding filaments rely on the reaction between actin and myosin. Calcium ions bind to the troponin complex on the actin filaments and cause the tropomyosin to change the orientation of the actin filament to expose the myosin head binding sites on the actin filament. Glycolysis and aerobic respiration generate adenosine triphosphate
