The correct Answer is:
To determine how many statements are correct regarding the parathyroid gland, let's analyze each statement one by one: 1. **Statement (a)**: "Four parathyroid glands present on the front side of the thyroid gland." - **Analysis**: The parathyroid glands are typically four small glands located on the back side of the thyroid gland, not the front. Therefore, this statement is incorrect. 2. **Statement (b)**: "It secretes parathromone which is steroidal in nature." - **Analysis**: The hormone secreted by the parathyroid glands is called parathyroid hormone (PTH), also known as parathormone. This hormone is a peptide hormone, not steroidal. Thus, this statement is also incorrect. 3. **Statement (c)**: "It increases blood Ca^(++) level." - **Analysis**: The primary function of parathyroid hormone is to increase the concentration of calcium ions (Ca^(++)) in the blood. This statement is correct. 4. **Statement (d)**: "It acts on bone and stimulates bone resorption." - **Analysis**: Parathyroid hormone does act on bones and stimulates bone resorption, which leads to the release of calcium into the bloodstream. This statement is also correct. **Conclusion**: - From the analysis, we found that statements (c) and (d) are correct, while statements (a) and (b) are incorrect. Therefore, the number of correct statements regarding the parathyroid gland is **2**. ### Summary of Correct Statements: - Correct Statements: 2 (c and d) - Incorrect Statements: 2 (a and b)
