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