Annotation rationales
Cardiomyocytes are electrically excitable, striated muscle cells whose sarcomeres and calcium-handling systems are specialized for rhythmic contraction.
Functional implications
Their synchronized force generation pumps blood, while metabolic and mechanosensory programs adapt cardiac output to workload and physiological stress.
