The Process Whose Specific Outcome Is the Progression of the Skeletal Muscle Fiber Over Time From Its Formation to the Mature Structure. Muscle Fibers Are Formed by the Maturation of Myotubes. They Can Be Classed As Slow Intermediate/fast or Fast.
A Contractile Actin Filament Bundle That Consists of Short Actin Filaments with Alternating Polarity Cross Linked by Alpha Actinin and Possibly Other Actin Bundling Proteins and with Myosin Present in a Periodic Distribution Along the Fiber.
Any of the Various Filamentous Elements That Form the Internal Framework of Cells and Typically Remain After Treatment of the Cells with Mild Detergent to Remove Membrane Constituents and Soluble Components of the Cytoplasm. the Term Embraces Intermediate Filaments Microfilaments Microtubules the Microtrabecular Lattice and Other Structures Characterized by a Polymeric Filamentous Nature and Long Range Order Within the Cell. the Various Elements of the Cytoskeleton Not Only Serve in the Maintenance of Cellular Shape But Also Have Roles in Other Cellular Functions Including Cellular Movement Cell Division Endocytosis and Movement of Organelles.
A Filamentous Structure Formed of a Two Stranded Helical Polymer of the Protein Actin and Associated Proteins. Actin Filaments Are a Major Component of the Contractile Apparatus of Skeletal Muscle and the Microfilaments of the Cytoskeleton of Eukaryotic Cells. the Filaments Comprising Polymerized Globular Actin Molecules Appear As Flexible Structures with a Diameter of 5 9 Nm. They Are Organized Into a Variety of Linear Bundles Two Dimensional Networks and Three Dimensional Gels. in the Cytoskeleton They Are Most Highly Concentrated in the Cortex of the Cell Just Beneath the Plasma Membrane.
Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose.
