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‚

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

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

muscle tissue: skeletal‚ smooth‚ and cardiac. Skeletal muscle was investigated in this lab. Skeletal muscle is composed of two filaments called actin and myosin‚ which run parallel to each other. Actin has a protein that run along it called tropomyosin‚ that prevents actin from binding to it‚ unless calcium is bound to a part of the tropomyosin called troponin. Sets of actin and myosin filaments are divided into individual units called sarcomeres. Sarcomeres are what gives skeletal muscle tissue its

If so‚ list what they are and what precautions should be taken. Handle the microscope and the slides with care; when taking the chicken bone out of the oven use caution because the bone is extremely hot. Exercise 1: The Chemical Components of Bone Questions A.
