ABSTRACT
In the following sections, two problems most useful in analyzing the safety of work processes are discussed: the properties of skeletal muscles and computerized methods.
Almost half the mass of the human body consists of muscles, of which there are 640 (Fidelus et al. 1983). There are three types of muscles: skeletal or striated, smooth, and cardiac. The system of human movement is driven by the skeletal muscles, of which there are 440. All our external activities are carried out with their help. On the microscopic level, skeletal muscles are composed of hundreds or thousands of parallel cells — muscle fibers enwrapped in a common sheath.
