A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins. The myofibril assembly process by which the muscle actomyosin is organized 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. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures containing both actin and myosin. The myosin may be organized into filaments. The cellular component assembly that is part of the initial shaping of the component during its developmental progression. The developmental process pertaining to the initial formation of an anatomical structure from unspecified parts. This process begins with the specific processes that contribute to the appearance of the discrete structure and ends when the structural rudiment is recognizable. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. The aggregation, arrangement and bonding together of a cellular component. Formation of myofibrils, the repeating units of striated muscle. The process whose specific outcome is the progression of a striated muscle cell over time, from its formation to the mature structure. Striated muscle cells contain fibers that are divided by transverse bands into striations, and cardiac and skeletal muscle are types of striated muscle. The aggregation, arrangement and bonding together of proteins to form the myosin-based thick filaments of myofibrils in striated muscle. The aggregation, arrangement and bonding together of proteins to form the actin-based thin filaments of myofibrils in striated muscle. The process by which cellular structures, including whole cells or cell parts, are generated and organized. Morphogenesis pertains to the creation of form. The process whose specific outcome is the progression of the cardiac myofibril over time, from its formation to the mature structure. A cardiac myofibril is a myofibril specific to cardiac muscle cells. The process whose specific outcome is the progression of a muscle cell over time, from its formation to the mature structure. Muscle cell development does not include the steps involved in committing an unspecified cell to the muscle cell fate. The process by which sarcomeres are added in series within a fiber. 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. The process whereby a relatively unspecialized cell acquires specialized features of a striated muscle cell; striated muscle fibers are divided by transverse bands into striations, and cardiac and voluntary muscle are types of striated muscle.
