medical history who recently suffered a femur head fracture that presented as osteoporosis. By definition‚ osteoporosis is a progressive bone disease that leaves the bones weak and unable to sustain any weight or pressure. Osteoporosis occurs when the body makes too little or not enough bone‚ causing the bones to break or fracture easily with a simple fall. Both the spongy and compact bone is affected when osteoporosis is present. The main difference between these two bones is‚ the spongy bone is

Determining the Latent Period 1. Click Clear Tracings to erase the oscilloscope display. The voltage should be set to 5.0 volts. 2. Drag the 200 msec button to the right edge of the oscilloscope. 3. Click the Stimulate button once‚ and allow the tracing to complete. 4. When you measure the length of the latent period from a printed graph‚ you measure the time between the application of the stimulus and the beginning of the first observable response(increase in force). The computer can’t “look ahead

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
