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

    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

    Muscle adaptations to the increase in energy demands at the start of exercise Introduction The transition from rest to exercise is associated with a huge upsurge in energy expenditure‚ due primarily to skeletal muscle contractions (Connett & Sahlin‚ 1996). Contractions require energy in the form of adenosine tri-phosphate (ATP). ATP stores in muscle are around 8mmol/l and are exhausted within 2s of exercise (Connett & Sahlin‚ 1996). To continue exercise and maintain ATP homeostasis‚ ATP
