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 the atrial 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 cardiac muscle cell over time, from its formation to the mature state. 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 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 whose specific outcome is the progression of a cardiac cell over time, from its formation to the mature state. A cardiac cell is 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.
