Verified step by step guidance

Understand the characteristics of cardiac muscle: Cardiac muscle is a type of muscle tissue found in the heart. It is responsible for the heart's contraction and is under involuntary control, meaning it functions without conscious effort.

Identify the features of cardiac muscle: Cardiac muscle cells are striated, which means they have a striped appearance due to the arrangement of actin and myosin filaments. They also have intercalated discs, which are specialized connections between cells that facilitate synchronized contraction.

Compare with skeletal muscle: Skeletal muscle cells are multinucleated, meaning they contain multiple nuclei per cell. This is a feature of skeletal muscle, not cardiac muscle.

Recognize the unique features of cardiac muscle: Cardiac muscle cells typically have a single nucleus, unlike skeletal muscle cells which are multinucleated. This is a key distinction between the two types of muscle tissue.

Determine the feature that does not belong: Based on the characteristics of cardiac muscle, the feature 'Multinucleated cells' does not apply to cardiac muscle, as cardiac muscle cells usually have a single nucleus.
