muscle contraction Introduction For a skeletal muscle fiber to contract‚ a stimulus must be applied to it. The stimulus is delivered by a nerve cell‚ or neuron. A neuron has a threadlike process called and axon that my run 91 cm or more to a muscle. A bundle of such fibers from man different neurons composes a nerve. A neuron that stimulates muscle tissue is called a motor neuron. The motor neuron branches into terminal structures called telodendria that come into close approximation with

ORGANIZATION GROUP FLOW In an organization‚ communication flows in 5 main directions- 1. Downward 2. Upward 3. Lateral 4. Diagonal 5. External 6. Laissez-faire 1. Downward Flow of Communication: Communication that flows from a higher level in an organization to a lower level is a downward communication. In other words‚ communication from superiors to subordinates in a chain of command is a downward communication. This communication flow is used by the managers to

Introduction: Skeletal muscle cells are specialized cells that contain multinucleated muscle fibers called myocytes. These myocytes contain thicker fibers that facilitate the release of calcium‚ the generation of an action potential within the sarcolemma‚ and the subsequent production of a muscle contraction. Muscle contractions are a direct byproduct of motor unit recruitment‚ and for this lab we can examine these effects with aid of a finger pulse transducer and a bar stimulus electrode. The

Sarah thinks hyperplasia may be the cause of her severe muscle soreness. Hyperplasia is where the splitting of muscle fibers cell as a response to resistance training. Hyperplasia also allows for muscles to adapt to the resistance‚ and grow in size or increase in strength. Delayed onset muscle soreness is he a result of microscopic tearing

Organization Early in human existence people learned that their individual efforts often fell short of success. They found that they were unable to accomplish many tasks that require more than individual effort. Therefore the necessity of group activity was discovered relatively early in human existence. Group activity could be aimed at some higher‚ more complex set of goals and could thus bring greater benefits to all concerned. This quality of group activity must be counted as one of the chief
