The correct Answer is:
To solve the question regarding the statements about morphine, we will evaluate each statement one by one. ### Step-by-Step Solution: 1. **Evaluate Statement I:** - The statement claims that morphine is an opioid drug that binds to specific opioid receptors present in the brain and gastrointestinal tract. - **Analysis:** This statement is correct. Morphine is indeed an opioid analgesic that interacts with opioid receptors in the brain and gastrointestinal tract, providing pain relief. 2. **Evaluate Statement II:** - The statement claims that the chemical diacetylmorphine is called smack or heroin. - **Analysis:** This statement is also correct. Diacetylmorphine is the chemical name for heroin, which is commonly referred to as "smack." 3. **Evaluate Statement III:** - The statement claims that heroin is obtained by acetylation of morphine, which is extracted from the latex of the Cannabis sativa plant. - **Analysis:** This statement is incorrect. While it is true that heroin is obtained by acetylation of morphine, morphine is extracted from the opium poppy plant, not from Cannabis sativa, which is the source of marijuana. 4. **Evaluate Statement IV:** - The statement claims that heroin is a central nervous system stimulant and causes hallucination. - **Analysis:** This statement is also incorrect. Heroin is a central nervous system depressant, not a stimulant. It can cause euphoria and may lead to hallucinations, but it primarily depresses the central nervous system. ### Conclusion: - Statements I and II are correct. - Statements III and IV are incorrect. Thus, the correct option is that statements I and II are true, while statements III and IV are false. ### Final Answer: The correct option is **D** (only statements I and II are correct). ---

Fill up the blanks in the following paragraph by selecting the correct option. Human beings have a significant ability to maintain and moderate the respiratory rhythm to suti the demands of the body tissues. This is done by the neural system. A specialised centre present in the medulla region of the brain called overset((i))"_______" is primarily responsible for this regulation. Another centre present in the pons region of the brain called overset((ii))"_______" can moderate the functions of the repiratory rhytm cenre. Neutral signal from this cenre cen reduce the duration of overset((iii))"_______" and thereby alter the respiratory rate. A overset((iv))"_______" is situated adjacent to the rhythm centre which is highly sensitive to CO_(2) and hydrogen ions.
