What type of muscle cell(s) have more than one nucleus?Multiple ChoiceSmooth muscle cells onlySkeletal muscle cells onlyCardiac muscle cells and smooth muscle cellsSmooth muscle cells and skeletal muscle cells

To answer the question step by step:

1. Identify the types of muscle cells:

   • Smooth muscle cells
   • Skeletal muscle cells
   • Cardiac muscle cells

2. Determine the number of nuclei in each type of muscle cell:

   • Smooth muscle cells: Typically have a single nucleus.
   • Skeletal muscle cells: Have multiple nuclei.
   • Cardiac muscle cells: Usually have one or two nuclei, but not more than that.

3. Analyze the options given:

   • Smooth muscle cells only: Incorrect, as smooth muscle cells typically have a single nucleus.
   • Skeletal muscle cells only: Correct, as skeletal muscle cells have multiple nuclei.
   • Cardiac muscle cells and smooth muscle cells: Incorrect, as cardiac muscle cells usually have one or two nuclei, and smooth muscle cells have a single nucleus.
   • Smooth muscle cells and skeletal muscle cells: Incorrect, as smooth muscle cells have a single nucleus.

4. Conclusion: The correct answer is Skeletal muscle cells only.
