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

Hope Muscular & Flexibility Project The Busy Traveler Class My class is focused on ’the busy traveler’‚ consisting of a group of older adults who work and travel often‚ spending a lot of time on airplanes or in hotels. They don’t stay in the same place long enough for a gym membership or big permanent‚ non-moveable equipment to be worth the money. Their strengths include things taken from working and traveling-- time management and recognition of the importance of getting in shape. Their weaknesses

Muscular Dystrophy‚ also referred to as “MD”‚ is a group of diseases that cause progressive weakness and loss of muscle mass (Mayo). In MD‚ abnormal genes interfere with the production of proteins needed to form the muscle’s health (Mayo). There are many long-term effects to this terrifying disease. The primary one‚ that being unable to walk. Muscular Dystrophy is a life-threatening disease that many pose questions and desire to learn more about. Muscular Dystrophy occurs in various forms. While

P5. Homeostasis is the process by which a constant internal environment is maintained by our body. For instance‚ this means that in our body‚ temperature‚ blood sugar levels‚ etc must be kept within a narrow range even when we are in a freezing climate‚ or while doing vigorous exercise etc. All homeostatic control mechanisms have at least three interdependent components which are: The receptor responds to changes in the environment‚ for example‚ detects temperature change. Then‚ after the receptor

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

Introduction “Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal equilibrium when dealing with external changes” (2). “Homeostasis keeps the body’s environment under control and keeps the conditions right for cells to live and function. Without the right body conditions‚ certain processes (e.g. osmosis) and proteins (e.g. enzymes) will not function properly” (1). Thermoregulation is the process that allows the cyclists

Homeostasis Lab Analysis Assigned Challenge: Doorframe Look at the data for your assigned challenge. Why did the “guinea pig’s” body react the way it did during the challenge? What was happening inside of the body that you couldn’t necessarily measure or see? The “guinea pig’s” body had the reaction of soreness and weakness as time increased because the body was using more and more energy as time passed with little rest. The form of pushing that every guinea pig was excelling on the doorframe
