Final answer:
Cardiomyocytes are similar to skeletal muscle because they are striated and have intercalated discs. However, cardiomyocytes are involuntary and typically have a single centrally located nucleus.
Step-by-step explanation:
Cardiomyocytes, also known as cardiac muscle cells, are similar to skeletal muscle in several ways. Firstly, they are striated, meaning they have alternating light and dark bands. Additionally, they both contain intercalated discs, which are specialized cell junctions that allow for synchronized contraction. However, unlike skeletal muscle, cardiomyocytes are involuntary and not under voluntary control. Lastly, while skeletal muscle cells are multinucleated, cardiomyocytes typically have a single centrally located nucleus.
