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

Thato’s muscle had remained unused for 6 weeks. Once the cast is removed and he steps down from the examination table‚ his muscle begins to contract. Due to this 6 week period of rest‚ the muscles initial strength of contraction may be significantly low as compared to its strength a few minutes later. The strength of contraction of his muscle increases to a plateau‚ which is termed the staircase effect. Due to his muscles low initial strength of contraction‚ Thato loses his balance and falls. 1

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

HOW TO GAIN MUSCLES. Introduction. The assignment topic touches on a very important part of the human body a muscle. This is a soft tissue found on most animals and is made of cells that contain protein filaments of actin and myosin that slide past one another‚ producing a contraction that changes both the length and the shape of the cell. It function to produce force there location on the body or according to the functions and roles they play. They are the cardiac muscles (muscles covering 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
