A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products.

Skeletal muscle cells are multinucleated because they consist of several cells that have fused together. Muscle cells contain many mitochondria and the characteristic protein filaments(myosin and actin) which are responsible for the muscle contraction. Terminology: the prefix sarco-and myo-both relate to muscle.
Muscle tissue is responsible for most types of body movement. I. Types of muscle: A. Striated muscle-skeletal musculature, striated in appearance under microscope. Cells are unbranched and are multinucleate syncytia.These muscles are capable of voluntary, quick, forceful contractions.s a result, neurotransmitters have to diffuse across this connective tissue layer and onto the plasmalemma of the smooth muscle cells in order to initiate the action potential that causes contraction. This is another reason for the slower contraction of smooth muscle cells.
