Muscle contraction is used to move parts of the body , as well as ... muscles, smooth muscles are use to sustain longer contraction or even near permanent whereas the striated ... ). Physiology See also muscle contraction The three types of muscle have significant ...

Cytoskeleton

... or cell-to-matrix junctions and the transduction of signals. They are also important for cytokinesis and, along with myosin , muscular contraction . Intermediate Filaments Main article: intermediate filaments These 8 to 11 nanometers in diameter filaments are the more stable ...

Enzyme

... starve for oxygen even with an abundance of oxygen without the action of the enzyme, cytochrome oxidase. Enzymes are also necessary for muscle contraction and relaxation. The fact is, without both of these classes of enzymes, (digestive and metabolic) life could not exist. Enzyme naming ...

Meiosis

... fertilization ). Oocytes that are not ovulated do not complete meiosis I. The end of Prophase I (also known as Prometaphase I ) is signified by contraction and staining of all chromosomes, as well as the polar migration of centrioles , the dispersion of the nucleoli and nuclear envelope and the ...

Myosin

... Myosin is a motor protein filament found in muscle tissue . Together with actin filaments, myosin provides the mechanism for muscle contraction , utilizing energy from ATP . The specific conformational rearrangements throughout the chemo-mechanical transduction process are still not known. ...
