The correct Answer is:
### Step-by-Step Text Solution: 1. **Understanding Muscle Types**: - Muscles in the body can be classified into two main types based on their control: voluntary and involuntary muscles. - Voluntary muscles are those that are under conscious control (e.g., moving your arm), while involuntary muscles operate without conscious control (e.g., heart beating). 2. **Identifying Heart Muscles**: - The heart is primarily made up of a specific type of muscle known as cardiac muscle. - Cardiac muscles are responsible for the contraction and relaxation of the heart, enabling it to pump blood throughout the body. 3. **Characteristics of Cardiac Muscles**: - Cardiac muscles are striated, meaning they have a banded appearance due to the arrangement of their fibers. - They are also involuntary, meaning their movement is not consciously controlled by the individual. 4. **Conclusion**: - Based on the characteristics of heart muscles, we can conclude that heart muscles are involuntary and striated. - Therefore, the correct answer to the question "Heart muscles are" is that they are involuntary and striated muscles.
