HW: “Fatigue” Summary In Jane Brody’s essay “Fatigue” in Text and Context‚ she reveals that more and more people today commonly complain to doctors‚ friends‚ and relatives about their fatigue. But Brody points out that fatigue is diverse and only “rarely” relates to excessive physical exertion. With that said‚ what other ailments can lead to ones fatigue other than activity? Brody continues her essay with the answer‚ “there are three main categories of fatigue”‚ these are physical fatigue‚ pathological

The two main processes involved in muscle contraction are cross-bridge cycling and the length-tension relationship‚ which normally function to maximize contraction in the muscle. Beginning with the activation of a motor unit‚ the ions flow from the motor unit towards the muscle fibers that it innervates by the motor neuron in the same way as a normal muscle would. However since the tissue is damaged‚ the force that is generated by these muscle fibers will not be as great‚ leaving the fibers less

Muscular System: Muscle Metabolism 1. List the three roles of ATP in muscle contraction: 1. _energizing the power stroke of the myosin cross bridge________________________ 2. _disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke_________________ 3. _energizing the calcium ion pump; transporting calcium___________________ 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called _hydrolysis________________________

Fatigue is a subjective feeling of tiredness which is distinct from weakness. Unlike weakness‚ fatigue can be alleviated by periods of rest. Fatigue can have physical or mental causes. Physical fatigue is the transient inability of a muscle to maintain optimal physical performance. Muscle fatigue is mainly caused by the limitations of a nerve’s ability to generate a continued signal and the reduced ability of the muscle fiber to contract. Many muscle properties change during fatigue including the

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 can contract when an electrical stimulus
