1. **Identify the Question**: The question asks for the most abundant mineral in the animal body from the given options: sodium, calcium, potassium, and iron.

2. **Analyze the Options**:
- **Sodium**: While important for various bodily functions, it is not the most abundant mineral.
- **Calcium**: Known to be a major component of bones and teeth, and plays crucial roles in several physiological processes.
- **Potassium**: Important for cellular function and nerve transmission, but not as abundant as calcium.
- **Iron**: Essential for oxygen transport in the blood, but present in smaller quantities compared to calcium.

3. **Determine the Correct Answer**: Based on the analysis, calcium stands out as the most abundant mineral in the animal body due to its significant presence in bones and teeth.

4. **Explain the Importance of Calcium**: Calcium is not only the most abundant mineral but is also vital for:

- Nerve impulse transmission

5. **Discuss the Consequences of Calcium Deficiency**: A lack of calcium can lead to health issues such as:
- Deformed bones
- Muscle spasms
- Conditions like rickets, particularly due to vitamin D deficiency which is necessary for calcium absorption.

6. **Conclusion**: Therefore, the most abundant mineral in the animal body is calcium.
