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 known as

INVESTIGATION OF PHYSIOLOGICAL & MECHANICAL PROPERTIES OF SKELETAL MUSCLE USING FROG GASTROCNEMIUS AIM The purpose of this experiment was to demonstrate the physiological as well as mechanical properties of skeletal muscle using the gastrocnemius muscle of a frog by exploring five different investigations namely the single twitch‚ the graded response‚ the relationship between muscle length and tension‚ muscle tetanus‚ and muscle fatigue. These individual experiments aim to explore the way muscles

It is generally regarded that contact sports are beneficial to children. This is due to the fact that the majority of bone density material is developed when the person is young. This is beneficial to people because many bone diseases such as osteoporosis are connected to low bone density and inactivity as a young adult. On the flip-side when competing in high impact sport there is a very high chance of some sort of injury occurring along the way. For example if someone dislocates their shoulder

Osteoporosis‚ Osteoarthritis‚ and Muscular Atrophy Osteoporosis and Osteoarthritis are both diseases of the bone. Osteoporosis actually means “porous bones” and is a problem with bones where there isn’t enough calcium in them to give them strength. This is because the bone cells aren’t being reproduced as fast as the bone is aging or deteriorating which causes the bones to become fragile. This can happen because of loss of calcium in the bone‚ or a problem with the calcium being absorbed correctly

LAB EXERCISE 2 THE PHYSIOLOGY OF SKELETAL MUSCLE (Martini p. 306-316) Work in groups of 4 Objectives: Name and describe the phases of a muscle twitch. Explain why the "all or none" law is reflected in the activity of a single muscle cell but not in an intact skeletal muscle. Understand that the graded response of skeletal muscle is a function of the number of muscle fibers stimulated and the frequency of the stimulus. Define and explain the physiological basis of the following: - subminimal‚
