Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

that it either be destroyed or ruled carefully by a resident prince. Machiavellis insistence on the practicality of his political advice is most evident in his consideration of the personality‚ character‚ and hereditary principalities‚ which are inherited by the ruler. No matter what idealistic notions are adopted as principles of private morality‚ he argued‚ there is no guarantee that other people will follow them‚ and that puts the honorable or virtuous individual at a distinct disadvantage

Which country would you rather be ill in and why? Health systems have played a part in the dramatic rise in life expectancy that occurred during the 20th century. They have contributed enormously to better health and influenced the lives and well-being of billions of people around the world. Their role has become increasingly important. The National Health Service was set up in the 1940s‚ post-war Britain‚ based on the principle of universal healthcare free at the point of use‚ financed entirely

Reyes November 08‚ 2011 Dr. Dunaway Neuronal signaling in muscle contraction is triggered when an action potential reaches the neuromuscular junction. At this junction‚ acetylcholine (ACh) is the main neurotransmitter. Packaged in vesicles‚ ACh fuses with the neuron’s membrane and is released into the synaptic cleft. ACh diffuses toward the motor end plate and bind to the neurotransmitter receptor on it. The muscle fiber is then triggered to produce an action potential of its own that

Muscle spasms are involuntary contractions of muscles that are often very painful. Muscle spasms are also called cramps or referred to as a “Charley horse”. These contractions are most frequent on the leg muscles but can also occur in the hands‚ arms and abdomen. (www.webmd.com) Typically the muscles become very hard and tight. There are many causes of muscle spasms. The most common cause is overuse during athletic activities such as sports or general exercise. Other causes include not

The purpose of this study is to utilize the banana sap as an alternative ingredient which very abundant source of quality ink. In addition‚ it maximizes the use of banana which grows abundantly in any rural areas and that it minimize the problem on waste disposal. The researcher also considers the challenge of doing this project being the first to do this study. The excitement as

order for a muscle to contract requires a nerve impulse to arrive at the neurotransmitter junction. This then causes a release of acetylcholine (ACh) from the presynaptic terminal. By binding with its receptors on the membrane of the muscle fiber‚ which opens sodium channels generating an action potential that spreads through the length of the fiber‚ stimulating release of calcium from the sarcoplasmic reticulum. Calcium is what activates the contractile mechanism‚ causing the muscle fiber to shorten
