Moral Muscle can be defined as pushing ourselves to do more than the minimum in our moral life. Moral Muscle is not just having physical strength but metal strength. The phrase Moral Muscle is a metaphor in which shows a type of strength someone obtains mentally. Someone who exercises his or her moral muscles has an mindset to do the right thing. Someone is considered to have moral strength when they restrict themselves from doing bad things and in place of that commit good thing. Moral strength

Lab 6: Amphibian Muscle Contraction Results: For this experiment‚ Isometric contractions of the gastrocnemius muscle of a frog were analyzed and from this data the latent period‚ twitch‚ motor unit summation‚ tetanus‚ fatigue & mechanical summation were measured. The data was used to quantify the effect of passive tension on the twitch force‚ effect of stimulus intensity on the twitch force‚ effect of stimulus frequency on contractile force of xenopus gastrocnemius muscle. The threshold voltage

Skeletal‚ Muscular‚ and Integumentary System The Muscular System Our muscular system provides the main source of force to put our bodies into motion. More than 40% of our body mass is composed of muscle. Types of Muscular Tissue There are three types of muscle tissue: 1. Skeletal Voluntary movement‚ attached to bones. 2. Smooth Involuntary movement‚ found in digestive tract‚ circulatory system‚ etc. 3. Cardiac Involuntary movement‚ found only in heart. Muscle Contraction Skeletal Muscle

Asthma is a condition of the respiratory which is caused by the tightness of the muscles in the airways‚ which therefore causes the individual with this condition to breathe out reduced amount of air which then leads to difficulty in inhaling and exhaling. According to the World Health Organization (2010)‚ this condition is due to inflammation of the air passages in the lungs and affects the sensitivity of the nerve endings in the airways so they become easily irritated. In an attack‚ the lining

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________________________
