in safety-related activities such as operating a motor vehicle‚ piloting an aircraft‚ performing surgery‚ or running a nuclear reactor‚ the consequences of fatigue can be disastrous.” Fatigue is a major contributor to human error (1). For example‚ blurred vision caused by sleepiness can cause numbers to blur and sounds to blend together. Fatigue‚ however‚ is not the only source of human error; there are many factors and conditions that lead to human error. Over confidence in one’s self can cause negligence

“Human error versus human capability: Which way should the pendulum swing?” Human factors can be defined as “the technology concerned to optimize the relationship between people and their activities by the systematic application of the human sciences‚ integrated within the framework of system engineering” (Edwards‚ 1988‚ p. 9). Human factors have evolved over the years since the birth of tools many millennia ago (Civil Aviation Authority‚ 2002). The modern evolution of human factors happened in

Diseases of the Muscular System There are over 650 muscles in the human muscular system. Each muscle has a specific role to perform. These muscles help us talk‚ walk‚ sit‚ run‚ eat‚ move about‚ hold things‚ and most important the continuous pumping of the heart muscles keeps us alive. Muscular system diseases cause many problems in the human body‚ that affects the mobility and functioning of various parts of the body. The list is very long as there are number of disorders that affect the human body
