Question

Which of the following are characteristics shared by both cardiac and smooth muscle? Select all that apply.

a. Involuntary
b. Striated Long
c. Found in the heart
d. Uninucleated

Answer 1

Cardiac and smooth muscles both share the characteristics of being involuntary and found in the heart. However, smooth muscles differ from cardiac muscles in terms of being uninucleated and not striated.

Step-by-step explanation:

Cardiac and smooth muscles share the following characteristics:

• Involuntary: Both cardiac and smooth muscles are involuntary, meaning they are not under conscious control.
• Found in the heart: Cardiac muscle is specifically found in the heart, while smooth muscle is found in various organs and structures throughout the body.

Smooth muscles, however, differ from cardiac muscles in that they are:

• Uninucleated: Smooth muscle cells have a single nucleus, while cardiac muscle cells can have multiple nuclei.
• Not striated: Unlike cardiac muscle, smooth muscle lacks striations or cross-striations. It appears smooth under a microscope.
