What type of muscles do not contain striations?

  1. Cardiac muscles

  2. Skeletal muscles

  3. Smooth muscles

  4. Voluntary muscles

The correct answer is: Smooth muscles

Smooth muscles do not contain striations. Smooth muscles are found in the walls of internal organs such as the intestines, blood vessels, and bladder. Unlike skeletal and cardiac muscles, smooth muscles do not have the striated appearance due to the arrangement of actin and myosin filaments in a different pattern. Smooth muscles are involuntary muscles, meaning they are not under conscious control, unlike skeletal muscles, which are voluntary in nature. So, the correct answer is C.
