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

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 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.

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

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.

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 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.

Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached.

Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached.

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.
