Summarizing the structural and functional properties of skeletal muscle tissues, it can be considered :

Options

A. nonstriated involuntary muscle
B. nonstriated voluntary muscle
C. striated voluntary muscle
D. striated involuntary muscle

Answer

### Step-by-Step Solution:

1. **Understanding Muscle Tissue Types**:
- Muscle tissues are categorized into three main types: skeletal, cardiac, and smooth muscles. Each type has distinct structural and functional properties.

2. **Identifying Skeletal Muscle**:
- Skeletal muscles are characterized as striated (striped appearance) and voluntary (under conscious control). They are attached to bones and facilitate movement.

3. **Structural Properties of Skeletal Muscle**:
- Skeletal muscle fibers are long, cylindrical, and multinucleated. The striations are due to the arrangement of actin and myosin filaments within the muscle fibers, which are organized into sarcomeres.

4. **Functional Properties of Skeletal Muscle**:
- Skeletal muscles are responsible for voluntary movements, posture maintenance, and heat production. They contract in response to signals from the nervous system, allowing for precise control of movements.

5. **Distinguishing from Other Muscle Types**:
- Smooth muscles are non-striated and involuntary, found in walls of hollow organs. Cardiac muscles are striated but involuntary, found in the heart. These differences help in identifying skeletal muscle specifically.

6. **Conclusion**:
- Based on the structural and functional properties, skeletal muscle tissues are best described as striated and voluntary muscles, which are under the control of the brain and responsible for movement.
