CHAPTER 3: THE MUSCULAR SYSTEM Three Types of Muscle * Muscle tissue is a collection of cells that shorten during contraction which create tension that results in movement * Tendons are touch bands of connective tissue that join muscle with bones Skeletal muscles * Muscles that are attached to bone (by tendons and other tissue) * Comprise 30 to 40% of human body weight * Humans have conscious control (conscious muscle) over these muscles (the brain can tell them what to do)

ions during contraction of a skeletal muscle? Calcium is an important element for live. Calcium is found in the bones of animals and humans. In muscle contraction is produce as a result of Calcium ions ‚ Ca2+‚ It comes from rapid release from the cisternae of the sarcoplasmic reticulum which cause a chemical reaction between ATP and the myofilaments. Another important function of Calcium ions occurs during the state of resting muscle. During the state of resting muscle‚ calcium Ion is “maintaining

Exercise Electrocardiogram Lab Purpose The purpose of this lab is to understand the concepts of an electrocardiogram of a normal person as well as understand what a normal ECG and an exercise ECG look like when performing a Bruce protocol treadmill test. Methods Materials- Test subject‚ ECG-12lead‚ 10 electrodes‚ treadmill The subject must have the electrodes properly connected before starting the treadmill test. Remove any hair from the subject before placing the electrodes on. The

After running 2.5 kilometres and swimming 250 meters the average person would be quite tired/exhausted‚ but with the correct fitness exercises to work on cardiovascular endurance it would get easier and easier to run such an event. The reason your cardio performance can be improved is because the heart is a muscle‚ and like all other muscles in the body if you keep working it it will adapt to the workload given. This allows us to have direct control of how healthy one of the most important

Cardiovascular Physiology and Blood Pressure July 27‚ 2009 BY 409L - LW Blake Perry Lab Partners: Jennifer Rastegar and John Riopka Abstract This experiment was designed to observe a baseline heart rate and blood pressure and to examine various modifications of the two. This experiment utilized both the BiopacPro and PhysioEx computer programs. The PhysioEx program was used to simulate a heart rate and modifications to it. The BiopacPro program was used to monitor a volunteer’s blood pressure;
