Solution

  1. True - Cardiac muscle is striated, meaning it has a banded appearance due to the arrangement of the muscle fibers.
  2. False - Each cardiac muscle cell contains only one nucleus, unlike skeletal muscle cells which have multiple nuclei.
  3. True - Intercalated disks are indeed found between cardiac muscle cells. They help to synchronize the contraction of the heart muscle.
  4. False - Cardiac muscle cells are not voluntarily controlled. They are controlled by the autonomic nervous system.
