The correct Answer is:
To determine which of the given statements are not related to rheumatoid arthritis, we can analyze each statement based on the characteristics of the disease. 1. **Understanding Rheumatoid Arthritis**: Rheumatoid arthritis is an autoimmune disorder where the immune system mistakenly attacks the body's own tissues, particularly the joints. This leads to inflammation, pain, and damage to the joints. 2. **Analyzing Each Statement**: - **Statement I: It affects neuromuscular junction**: This statement is **not related** to rheumatoid arthritis. Rheumatoid arthritis primarily affects the joints, not the neuromuscular junction. Conditions like myasthenia gravis affect the neuromuscular junction. - **Statement II: Body attacks self cells**: This statement is **related** to rheumatoid arthritis. In autoimmune disorders, the immune system attacks the body's own cells. - **Statement III: More antibodies are produced in the body**: This statement is **related** to rheumatoid arthritis. In autoimmune diseases, the body produces antibodies against its own tissues. - **Statement IV: The ability to differentiate pathogens or foreign molecules from self cells is lost**: This statement is **related** to rheumatoid arthritis. The immune system fails to distinguish between self and non-self cells in autoimmune disorders. 3. **Conclusion**: The only statement that is not related to rheumatoid arthritis is **Statement I**. ### Final Answer: **The statement that is not related to rheumatoid arthritis is: I) It affects neuromuscular junction.** ---
