Microscopic Picture of Muscular Tissue
Which characteristics are common to both cardiac and smooth muscle? Select all that apply.
Involuntary
Uninucleated
Long
Striated
Found in the heart
Solution
The characteristics common to both cardiac and smooth muscle are:
Involuntary
Uninucleated
Explanation for each option:
Involuntary: Both cardiac and smooth muscles are controlled involuntarily, meaning they function without conscious control.
Uninucleated: Both types of muscle cells typically have a single nucleus.
Long: This characteristic is not common to both. Smooth muscle cells are spindle-shaped and relatively short, while cardiac muscle cells are branched and also not particularly long.
Striated: This characteristic is not common to both. Cardiac muscle is striated, but smooth muscle is not.
Found in the heart: This characteristic is specific to cardiac muscle only.
In summary, the common characteristics of both cardiac and smooth muscle are that they are involuntary and uninucleated.
