The myofibrils are composed of actin and myosin filaments called myofilaments, repeated in units called sarcomeres, which are the basic functional, contractile units of the muscle fiber necessary for muscle contraction. (wikipedia.org)
The contraction of each muscle fiber bundle is controlled through the nerve impulses directed into the fiber bundle by a neuron, a type of electrical relay that is connected to the larger nervous system. (faqs.org)
When nerve impulses are communicated to the muscle, a complex series of electrochemical reactions convert the impulse into a muscle contraction. (faqs.org)
The actual muscle contraction generate within the muscle is fueled by the chemical reaction that occurs involving the compound adenosine triphosphate (ATP), which participates in a series of energy-producing reactions that involve creatine phosphate, present in the muscle cell, and gylcogen, transported to the cell through the blood as glucose.
