The developmental sequence of events leading to the formation of adult skeletal muscle tissue. The main events are: the fusion of myoblasts to form myotubes that increase in size by further fusion to them of myoblasts, the formation of myofibrils within their cytoplasm and the establishment of functional neuromuscular junctions with motor neurons. At this stage they can be regarded as mature muscle fibers.

Formation of myofibrils, the repeating units of striated muscle.

The process in which sarcomeres are added in series within a fiber.

The process in which sarcomeres are added in series within a fiber.

The aggregation, arrangement and bonding together of proteins to form the myosin-based thick filaments of myofibrils in striated muscle.

The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

The developmental process in which the size or shape of a cell is generated and organized.

The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.

The process whose specific outcome is the progression of cardiac muscle over time, from its formation to the mature structure.

The multicellular organismal process in which the heart decreases in volume in a characteristic way to propel blood through the body.

The process whose specific outcome is the progression of the skeletal myofibril over time, from its formation to the mature structure. A skeletal myofibril is a myofibril specific to skeletal muscle cells.

Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The aggregation, arrangement and bonding together of proteins to form the myosin-based thick filaments of myofibrils in skeletal muscle.

The aggregation, arrangement and bonding together of a filament composed of myosin molecules.

Any process in which a protein is transported to, and/or maintained in, a specific location at the level of a cell. Localization at the cellular level encompasses movement within the cell, from within the cell to the cell surface, or from one location to another at the surface of a cell.

Any process that activates or increases the frequency, rate or extent of locomotion of a cell or organism.

Any process that activates or increases the frequency, rate or extent of striated muscle contraction.

The aggregation, arrangement and bonding together of proteins to form the myosin-based thick filaments of myofibrils in striated muscle.

The developmental process by which a pharyngeal gland is generated and organized.

The sequential process in which the multiple coagulation factors of the blood interact, ultimately resulting in the formation of an insoluble fibrin clot; it may be divided into three stages: stage 1, the formation of intrinsic and extrinsic prothrombin converting principle; stage 2, the formation of thrombin; stage 3, the formation of stable fibrin polymers.

Any process that modulates the frequency, rate or extent of cell motility.

The process whose specific outcome is the progression of the adult somatic muscle over time, from its formation to the mature structure.

Any process in which a protein is transported to, and/or maintained in, the M band. The M band is the midline of aligned thick filaments in a sarcomere.

The midline of aligned thick filaments in a sarcomere; location of specific proteins that link thick filaments. Depending on muscle type the M band consists of different numbers of M lines.

The dark-staining region of a sarcomere, in which myosin thick filaments are present; the center is traversed by the paler H zone, which in turn contains the M line.

The midline of aligned thick filaments in a sarcomere; location of specific proteins that link thick filaments. Depending on muscle type the M band consists of different numbers of M lines.
