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

Physical During late adulthood‚ physicality becomes harder to attain. As adults get older they will eventually have hearing loss‚ restful sleep‚ weaker immune system‚ physical appearance and mobility‚ and touch sensitivity for some adults. “Physical declines become more apparent in late adulthood‚ as more organs and systems of the body are affected.” My grandmother experienced a few of these symptoms. Due to hearing loss‚ there were times people had to constantly repeat themselves while standing

1. Describe the main muscle groups of the body and their function There are three main categories that the muscles in the human body fall into: • Skeletal Muscle Skeletal muscle is the foremost area of concern for a sports masseuse. The main functions of this muscle group is to move the body in a voluntary manner‚ for example‚ if you want to kick a ball you will voluntarily have to send a signal through your brain to inform the muscles in your legs to contract/flex/extend and execute the skill

An activity that primarily utilizes type I muscle fibers is long distance running. Type I fibers are generally slow-twitch fibers‚ meaning they contract slowly and have a high capacity for aerobic glycolysis. Ectomorphs usually perform long distance running. In order to train slow twitch muscles (training slow twitch muscle fibers is for endurance purposes and other aerobic activities)‚ one must increase the time under tension (TUT). Specifically‚ one must focus on doing higher reps (12-15) and low

Introduction The aim of this paper seeks to examine the concept of total rewards in the process of increasing prominence in organisations. Total Rewards is best described as a business strategy that “includes financial and non-financial complementary elements designed to recruit‚ develop‚ retain and motivate employees”(OSP 2003). “Employees working for a total rewards employer tend to be more motivated‚ productive‚ and happy”. (eHow 1999) As a result is “the business thrives”(eHow 1999) and prominence

agreement to get the players back on the court playing the game they love. As Porter’s “Five Forces” model describes how certain areas of the industry could be affected or affecting the entire game‚ and people throughout the basketball world. The way that I look at this situation and in regards to the N.B.A. and the players‚ because of a strong competitive force in the industry‚ and according to Porter‚ these forces can be a threat on the entire involvement in basketball. The lockout brings forward a

Muscle Cell at rest: As the muscle cell is at rest it has a resting potential of -90mV. The K+ is all located inside the cell‚ the Na+ is located outside of the cell and the Ca2+ is located inside the sarcoplasmic reticulum. All leak channels and pumps are closed at this point. Muscle Cell stimulated by Acetylcholine: A motor neuron releases Acetylcholine which diffuses toward the muscle cell across the neuromuscular junction. As the Acetylcholine binds to a receptor on the muscle

The two articles‚ “What Happens To Your Body When You Freeze To Death” by Katherine Ripley and “Hypothermia- Cold Weather Health Risks” both identify the effects and stages of hypothermia. The videos‚ “What Hypothermia Does to Your Body and Brain” and “The Effects of Hypothermia” provide even more information about what your body experiences during hypothermia.

Print out the graph(s) that you see on the oscilloscope screen by clicking Tools at the top of the screen and then selecting Print Graph. What is the threshold voltage? ____0.8____ V How does the graph generated at the threshold voltage differ from the graphs generated at voltages below the threshold? There is no movement below the threshold. However‚ there is a tiny increase between 10 and 50 of the force line. A C T I

Prior to injecting the neurotoxin‚ Tubocurare‚ inside the gastrocnemius muscle‚ a control was established. The baseline was maintained approximately at 20 grams. The control used the maximum voltage of 0.75 volts for the stimulus input. As a result‚ the tension produced 68.13 grams of force. The moment Tubocurare was infused into the gastrocnemius muscle‚ the muscle tension dropped to 47.7 grams of force. Data was recorded for 10 minutes‚ and as predicted prior to the experiment‚ the tension trend
