Laboratory – Muscle Physiology A. MUSCLE TONUS Observations‚ Report and Conclusion: A. Define muscle tonus and give its importance * Muscle tonus refers to a state of slight muscular contraction maintained by synchronous impulses of low frequency‚ discharged by the spinal motor neurons. * Reflex in nature. * Muscle tonus is a small amount of tension in the muscle due to weak‚ involuntary contractions of its motor units. Muscle tonus is important in a sense that it governs the

How Energy is used in the Body (M1) We get chemical energy from food we eat and oxygen that we breathe –we need this to get energy into a usable form to be used by the cells Glucose + Oxygen ----------------> Carbon Dioxide + Water (C6H12O6) (O2) Metabolism (CO2) (H2O) (1C6H12O6) (6O2) In Cells (6CO2) (6H20) Metabolism is the process of getting chemical energy from larger molecules in food and breaking them down into smaller

results in the Lab Report. You answered: 426 ml O2/hr 1i. Now that you have calculated the oxygen consumption per hour for this rat‚ you can calculate the metabolic rate per kilogram of body weight with the following equation (note that you need to convert the weight data from grams to kilograms to use this equation). Metabolic rate = (ml O2/hr)/(weight in kg) = ml O2/kg/hr Enter the metabolic rate in the field below and then click Submit Data to display your results in the Lab Report. You answered:
