Muscle contractions tend to be smooth and vary in strengths‚ depending on the demands placed on them. The variations of strength are called graded muscle responses. There are two ways a muscle contraction can be graded‚ either by changing the frequency of stimulation or by changing the strength of the stimulation. When a muscle is responding to a change in stimulus frequency‚ the nervous system will reach a greater muscular force when increasing the firing of motor neurons. This causes a wave or

Influences of Fiber Optics Introduction: People have been trying to improve communications over the centuries. Communication plays a very important role in everyday life. The advancement of the world mostly depends on how we share the information with the rest of the world. Fiber optics is making this task easier and quicker. It is currently the fastest internet technology. Fiber optic is a technology of transmitting light through very thin flexible glass or plastic fibers. It is one of the fastest

HISTORY OF FIBER OPTICS * In 1840‚ Daniel Colladon and Jacques Babinet demonstrated the principle of guiding light by refraction. * It was followed by a public demonstration by John Tyndal in 1852. In 1870‚ Tyndal wrote about the property of total internal reflection in his book about the nature of light. * In 1880‚ Alexander Graham Bell and Sumner Tainter invented the Photophone‚ a device capable of transmitting sound waves over beam of light. This is considered as mankind’s first attempt

talk about how BUILDING MUSCLE INCORPORATES MANY DIFFERENT FACTORS BUT CAN ULTIMATELY BE ACHEIEVED BY NUTRION‚ WEIGHT TRAINGING‚ AND ADDING SUPPLEMENTS TO YOUR DAILY ROUTINE. Let’s start with nutrition. There are hundreds of fad diets out there today‚ however the foundation of a successful nutrition plan begins a healthy calorie controlled diet. You must be eating a consistent amount of daily calories. This intake should be substantial enough to allow the body to build muscle. Undereating is one of

naked eye. What is the skeletal system? The skeletal system is a very important part of the human body this consists of 206 bones‚ which together with different structures make the joints of the system. Within the skeletal system the structures present are the cartilage‚ bone tissues‚ fibrous connective tissues which form the ligaments of the bones Scanlon and Sanders‚ pp.122‚ 2014). The skeletal system consists of two main organs these are the ligaments and bones‚ the skeletal system functions by
