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

Compassion fatigue‚ also known as secondary traumatic stress (STS)‚ is a condition of gradual lessening of compassion over time (Sabo‚ 2011). It is common among individuals who work directly with victims of trauma like nurses‚ psychologists‚ physicians‚ cancer-care providers‚ emergency room personnel‚ chaplains‚ and other healthcare professionals. Nurses intend to provide compassionate and empathetic care to patients but become victims of continuous stress while meeting the needs of the clients and
