9. Describe the arrangement of muscle fibers to make a muscle. Cell membrane called sarcolemma and cytoplasm called sarcoplasm. Arranged with their long axes in parallel. Each fiber is sheath in connective tissue with groups of adjacent fibers bundled together in units called fascicles. 10. Define the terms sarcolemma‚ sarcoplasm‚ myofibrils‚ sarcoplasmic reticulum‚ terminal cisternae‚ t-tubules. Sarcolemma is the cell membrane of a muscle fiber‚ sarcoplasm is the cytoplasm‚ myofibrils

LABORATORY REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force

Manufacturing Polyester fibers‚ the synthetic fibers‚ are long chain polymers derived from coal‚ air‚ water‚ and petroleum. They are formed through chemical reaction between an acid and alcohol. In this reaction‚ two or more molecules combine to make a large molecule whose structure repeats throughout its length. These molecules are very stable and strong. There are variations in the compositions and therefore in the properties of polyester fibers. Types of Polyester The polyester fibers are generally

Understanding Your Fats and Fiber There are four major dietary fats that we in the foods that we may eat‚ transfats‚ saturated fats‚ monounsaturated fat and polyunsaturated fat. Eating some of these fats may raise the cholesterol in our bodies. The fats that are considered to be bad fats that we eat are trans fats and saturated because they raise the bad cholesterol (LDL) in our bodies. Monounsaturated fats and polyunsaturated fats are know to be the good fats and are know to help reduce bad

a particular paint chip Critical Thinking Questions 1. What are some of the challenges for forensic scientists in dealing with fiber evidence? A challenge for forensic scientists in dealing with fiber evidence is that they have to narrow down the likely source of the fibers in order for the fiber evidence to become important. It is often impossible to link a fiber found at a crime scene with the specific item that it came from‚ since there is a mass production of goods today‚ and since

suppressed. Optical amplifiers are important in optical communication and laser physics. There are several different physical mechanisms that can be used to amplify a light signal‚ which correspond to the major types of optical amplifiers. In doped fiber amplifiers and bulk lasers‚ stimulated emission in the amplifier’s gain medium causes amplification of incoming light. In semiconductor optical amplfiers (SOAs)‚ electron-hole recombination occurs. In Raman amplifiers‚ Raman scattering of incoming
