Q1. Arrange the three parts of the small intestine in the correct order, starting from the part nearest to the stomach:
छोटी आंत के तीन भागों को आमाशय के निकटतम भाग से आरंभ करते हुए सही क्रम में व्यवस्थित कीजिए:
- A. Ileum → Jejunum → Duodenum / शेषांत्र (इलियम) → मध्यांत्र (जेजुनम) → ग्रहणी (डुओडेनम)
- B. Jejunum → Duodenum → Ileum / मध्यांत्र (जेजुनम) → ग्रहणी (डुओडेनम) → शेषांत्र (इलियम)
- C. Duodenum → Ileum → Jejunum / ग्रहणी (डुओडेनम) → शेषांत्र (इलियम) → मध्यांत्र (जेजुनम)
- D. Duodenum → Jejunum → Ileum / ग्रहणी (डुओडेनम) → मध्यांत्र (जेजुनम) → शेषांत्र (इलियम)
Solution
The small intestine begins at the stomach as the C-shaped duodenum, continues as the jejunum and ends as the ileum, which opens into the large intestine.
छोटी आंत आमाशय से C-आकार की ग्रहणी (डुओडेनम) के रूप में आरंभ होती है, मध्यांत्र (जेजुनम) के रूप में आगे बढ़ती है तथा शेषांत्र (इलियम) के रूप में समाप्त होती है, जो बड़ी आंत में खुलती है।
Q2. Which of the following correctly describes the dentition of an adult human?
निम्नलिखित में से कौन-सा वयस्क मनुष्य के दंतविन्यास का सही वर्णन करता है?
- A. Dental formula 2132/2132, 32 teeth, acrodont and monophyodont / दंतसूत्र 2132/2132, 32 दाँत, अग्रदंती (एक्रोडॉन्ट) तथा एकबारदंती (मोनोफायोडॉन्ट)
- B. Dental formula 2123/2123, 32 teeth, thecodont, diphyodont and heterodont / दंतसूत्र 2123/2123, 32 दाँत, गर्तदंती (थीकोडॉन्ट), द्विबारदंती (डाइफायोडॉन्ट) तथा विषमदंती (हेटरोडॉन्ट)
- C. Dental formula 2143/2143, 44 teeth, thecodont and polyphyodont / दंतसूत्र 2143/2143, 44 दाँत, गर्तदंती (थीकोडॉन्ट) तथा बहुबारदंती (पॉलीफायोडॉन्ट)
- D. Dental formula 2123/2123, 20 teeth, pleurodont and homodont / दंतसूत्र 2123/2123, 20 दाँत, पार्श्वदंती (प्लूरोडॉन्ट) तथा समदंती (होमोडॉन्ट)
Solution
Adult humans have the dental formula 2123/2123 giving 32 teeth, and their teeth are thecodont (set in sockets), diphyodont (two sets in life) and heterodont (different types).
वयस्क मनुष्य का दंतसूत्र 2123/2123 होता है जिससे 32 दाँत बनते हैं, तथा उनके दाँत गर्तदंती (थीकोडॉन्ट — गर्तों में स्थित), द्विबारदंती (डाइफायोडॉन्ट — जीवन में दो समुच्चय) एवं विषमदंती (हेटरोडॉन्ट — विभिन्न प्रकार के) होते हैं।
Q3. The inactive proenzyme pepsinogen secreted by the gastric glands is converted into its active form, pepsin, by:
जठर ग्रंथियों द्वारा स्रावित निष्क्रिय प्रोएंजाइम पेप्सिनोजन इसके सक्रिय रूप, पेप्सिन में किसके द्वारा परिवर्तित होता है:
- A. Trypsin / ट्रिप्सिन
- B. Enterokinase / एंटेरोकाइनेज़
- C. Hydrochloric acid / हाइड्रोक्लोरिक अम्ल
- D. Bile salts / पित्त लवण
Solution
Hydrochloric acid of the gastric juice converts pepsinogen into active pepsin; once formed, pepsin can also autocatalytically activate more pepsinogen.
जठर रस का हाइड्रोक्लोरिक अम्ल पेप्सिनोजन को सक्रिय पेप्सिन में परिवर्तित करता है; एक बार बनने के बाद पेप्सिन स्वतः उत्प्रेरण द्वारा और अधिक पेप्सिनोजन को भी सक्रिय कर सकता है।
