The correct Answer is:
To determine how many of the statements P, Q, and R are false, let's analyze each statement one by one. **Step 1: Analyze Statement P** - Statement P: "Sesamoid joint is a type of fibrous joint between cranial bones." - Evaluation: This statement is false. Sesamoid joints are not fibrous joints; they are a type of synovial joint that forms within a tendon. The joints between cranial bones are actually sutural joints, which are a type of fibrous joint. Therefore, this statement is incorrect. **Step 2: Analyze Statement Q** - Statement Q: "IDDM is an autoimmune disorder." - Evaluation: This statement is true. IDDM (Insulin-Dependent Diabetes Mellitus), also known as Type 1 diabetes, is indeed classified as an autoimmune disorder. In this condition, the immune system attacks and destroys insulin-producing beta cells in the pancreas. **Step 3: Analyze Statement R** - Statement R: "Tetany is characterized by rapid spasms in nerve." - Evaluation: This statement is misleading but can be considered true in a broader context. Tetany is characterized by rapid muscular spasms, typically due to low calcium levels in the blood, rather than spasms in the nerve itself. However, it is often associated with neuromuscular excitability. Thus, while the wording is not precise, the essence of the statement is generally accepted as true. **Conclusion: Count the False Statements** - Based on the evaluations: - Statement P is false. - Statement Q is true. - Statement R is true (though slightly misleading). Therefore, there is **1 false statement** among the three. **Final Answer: 1** ---
