Introduction: In this lab‚ I will study how muscles contract‚ what makes muscles contract‚ different types of muscle contraction‚ and learn about how resistance affects muscle contraction. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Recruitment (or Multiple

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

Frog Skeletal Muscle The aim of this experiment is to explore the basic physiological principles of skeletal muscle using the isolated frog (Rana pipiens or Xenopus laevis) gastrocnemius muscle. Students will dissect a double-pithed frog. Then‚ they will connect the muscle to the Force Transducer to measure twitch recruitment‚ effect of stretch‚ muscle summation‚ muscle tetanus‚ and muscle fatigue. Written by staff of ADInstruments.

Chapter 10 Muscle The muscular system helps in providing the movement for bones and in doing so allows the body to make complex movements. Muscle is one of the four types of primary tissue. The three kind of muscle tissue that make up the human body are: skeletal muscle‚ smooth muscle‚ and cardiac muscle. Skeletal muscle is voluntary and are usually found attached to bones where they help to produce movement of the skeleton. Smooth muscle is involuntary and are usually found in the walls of the

of three different muscle types cardiac‚ smooth‚ and skeletal muscle. For this particular experiment the primary focus was skeletal muscle‚ which accounts for about 36% to 45% of total body weight and involves the integration of more than 600 different muscles (WordPress‚ 2006). Skeletal muscle contains many unique properties such as; elasticity and extensibility which allows a muscle to be stretched and return to its original state when not in use. Additionally skeletal muscles also contain a property

REVIEW SHEET EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to
