Unit 7 Review Sheet Accomplishments/Failures of Progressive Era: Passed reforms regarding Farmers and the Union workers. BUT no legislation regarding African Americans and racism. TR almost did w/ Booker T but received bad reviews from public. AFL (goals/tactics): Led by Samuel Gompers; an alliance of skilled workers in craft unions; concentrated on brea-and-butter issues such as higher wages‚ shorter hours‚ and better working conditions. Aligned w/ Democratic Party under Wilson. Alfred Mahan

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

Physiology of stomach:- For understanding approaches for gastro retention‚ it is essential to overview gastric physiology and gastric motility. The stomach is situated in the left upper part of the abdominal cavity immediately under the diaphragm. Human stomach has a resting volume of 25-50ml‚ which can distend upto1500ml following a meal. It is divided into 5 anatomical parts: a) Cardia:- First part of the stomach below the esophagus. It contains cardiac spincter‚which is a thin ring of muscle

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

sarcoplasmic hypertrophy (professional bodybuilders and endurance athletes).[citation needed] The first measurable effect is an increase in the neural drive stimulating muscle contraction. Within just a few days‚ an untrained individual can achieve measurable strength gains resulting from "learning" to use the muscle.[citation needed] As the muscle continues to receive increased demands‚ the synthetic machinery is upregulated. Although all the steps are not yet clear‚ this upregulation appears to begin with

MUSCLE FATIGUE HOW DO MUSCLES GET THE ENERGY TO WORK? In muscles‚ it is essential that Calcium is present‚ as this gives the muscles the ability to contract and relax. For muscles to contract energy is needed: the energy can only be provided by the breakdown of a chemical called adenosine triphosphate (ATP). As ATP is broken down‚ a phosphate molecule is broken off‚ reducing the phosphate molecules‚ from 3 to 2. This produces adenosine triphosphate. However for the muscles contraction to continue

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
