The process whose specific outcome is the progression of cardiac muscle over time, from its formation to the mature structure. The process whereby a relatively unspecialized cell acquires specialized features of a cardiac muscle cell in the atrium. Cardiac muscle cells are striated muscle cells that are responsible for heart contraction. The atrium is the part of the heart that receives blood into the organ. The process whose specific outcome is the progression of an atrial cardiac muscle cell over time, from its formation to the mature state. Cardiac muscle cells are striated muscle cells that are responsible for heart contraction. The atrium is the part of the heart that receives blood into the organ. The process whereby a relatively unspecialized cell acquires the specialized structural and/or functional features of a cell that will form part of the cardiac organ of an individual. The process whereby a cardiac muscle precursor cell acquires specialized features of a cardiac muscle cell. Cardiac muscle cells are striated muscle cells that are responsible for heart contraction. 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. The commitment of cells to atrial cardiac muscle cell fates and their capacity to differentiate into cardiac muscle cells of the atrium. Cardiac muscle cells are striated muscle cells that are responsible for heart contraction.
