Where is cardiac muscle primarily located?

Cardiac muscle is primarily located in the wall of the heart. This specialized type of muscle tissue is unique to the heart and is responsible for pumping blood throughout the body. It has distinct properties, including being involuntary and striated, allowing it to contract rhythmically and continuously without conscious control. The structure of cardiac muscle cells, or myocytes, includes intercalated discs, which facilitate communication and synchronization of contractions between the cells, essential for efficient heart function. This specialization and unique location are crucial for maintaining the heart's role in the circulatory system, distinguishing cardiac muscle from other types of muscle found in the body, such as smooth muscle in organ walls or skeletal muscle in limbs.
