D
Cardiac muscle
Verified step by step guidance
1
Step 1: Understand the characteristics of skeletal muscle tissue. Skeletal muscle cells, also known as muscle fibers, are long, cylindrical, and multinucleated. This is because they are formed by the fusion of multiple myoblasts during development.
Step 2: Compare skeletal muscle tissue to smooth muscle tissue. Smooth muscle cells are spindle-shaped and contain a single nucleus. They are found in the walls of hollow organs and are responsible for involuntary movements.
Step 3: Examine epithelial tissue. Epithelial tissue is not a type of muscle tissue. It consists of tightly packed cells that form protective layers or linings, and its cells typically have a single nucleus.
Step 4: Analyze cardiac muscle tissue. Cardiac muscle cells are branched and interconnected, and they usually contain one nucleus per cell. However, some cardiac muscle cells may have two nuclei, but this is not the norm.
Step 5: Conclude that skeletal muscle tissue is the only type of muscle tissue with cells that consistently contain multiple nuclei, distinguishing it from the other options provided.
