The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. Taking both ears together, the total number of ear ossicles present in the middle ears of an adult human being is:
दोनों कानों को मिलाकर, वयस्क मनुष्य के मध्य कर्णों में उपस्थित कर्ण अस्थिकाओं (ear ossicles) की कुल संख्या है:
- A. 6
- B. 4
- C. 8
- D. 3
Solution
Each middle ear contains three ossicles — the malleus, incus and stapes. Since there are two ears, the total number of ear ossicles is six, and these are counted among the 80 bones of the axial skeleton.
प्रत्येक मध्य कर्ण में तीन अस्थिकाएँ होती हैं — मैलियस, इंकस तथा स्टेपीज़। चूँकि दो कान होते हैं, अतः कर्ण अस्थिकाओं की कुल संख्या छह है, और इन्हें अक्षीय कंकाल की 80 हड्डियों में गिना जाता है।
Q2. The occurrence of rapid spasms (wild contractions) in muscle due to a low level of Ca2+ in the body fluid is known as:
शरीर द्रव में Ca2+ के निम्न स्तर के कारण पेशी में तीव्र ऐंठन (अनियंत्रित संकुचन) का होना किस नाम से जाना जाता है?
- A. Tetanus / टिटैनस
- B. Gout / गाउट
- C. Arthritis / आर्थराइटिस
- D. Tetany / टिटैनी
Solution
Tetany is caused by a fall in body-fluid Ca2+, producing rapid, uncontrolled muscle spasms; tetanus, gout and arthritis have different causes.
टिटैनी शरीर-द्रव में Ca2+ के गिरने से उत्पन्न होती है, जिससे तीव्र, अनियंत्रित पेशी ऐंठन होती है; टिटैनस, गाउट और आर्थराइटिस के भिन्न कारण होते हैं।
Q3. The thin fibrous membrane that bisects each isotropic (I) band and marks the boundary between two successive sarcomeres is also known as:
वह पतली तंतुमय झिल्ली जो प्रत्येक समदैशिक (isotropic, I) पट्टी को द्विभाजित करती है और दो क्रमागत सार्कोमियरों के बीच की सीमा को चिह्नित करती है, उसे निम्नलिखित में से किस नाम से भी जाना जाता है:
- A. The sarcolemma / सार्कोलेमा
- B. The H zone / H क्षेत्र
- C. The M line / M रेखा
- D. Krause's membrane / क्राउस की झिल्ली
Solution
The Z line, which bisects the I band and delimits each sarcomere, is also called Krause's membrane. The H zone and M line lie within the A band, and the sarcolemma is the fibre's plasma membrane.
Z रेखा, जो I पट्टी को द्विभाजित करती है और प्रत्येक सार्कोमियर को परिसीमित करती है, क्राउस की झिल्ली (Krause's membrane) भी कहलाती है। H क्षेत्र तथा M रेखा A पट्टी के भीतर स्थित होते हैं, और सार्कोलेमा तंतु की प्लाज़्मा झिल्ली है।
