Verified step by step guidance

Step 1: Understand the concept of intercalated discs. Intercalated discs are specialized structures found in muscle tissue that facilitate communication and synchronized contraction between cells.

Step 2: Recall the types of muscle tissue in the human body: skeletal muscle, cardiac muscle, and smooth muscle. Each type has distinct characteristics and functions.

Step 3: Learn the unique features of cardiac muscle tissue. Cardiac muscle is found in the heart and is responsible for pumping blood. It has striations like skeletal muscle but also contains intercalated discs, which are not present in skeletal or smooth muscle.

Step 4: Compare cardiac muscle with other muscle types. Skeletal muscle is voluntary and lacks intercalated discs, while smooth muscle is involuntary and also lacks intercalated discs. Connective tissue is not a type of muscle tissue and does not contain intercalated discs.

Step 5: Conclude that intercalated discs are a defining feature of cardiac muscle tissue, enabling the synchronized contraction necessary for the heart's function.
