Question

Match the numbered parts of the vocal tract (in the diagram given below) with the correct label from those given in the box and choose the appropriate option. \includegraphics[width=0.5\linewidth]{3.png}
Labels: a. Labial cavity
b. Pharyngeal cavity
c. Alveolar ridge
d. Laryngeal cavity

• A. 1-b; 2-d; 3-c; 4-a
• B. 1-d; 2-b; 3-a; 4-c
• C. 1-d; 2-c; 3-b; 4-a
• D. 1-b; 2-d; 3-a; 4-c

Hint:

When matching vocal tract parts, always remember: - \textbf{Pharyngeal cavity} = throat area. - \textbf{Laryngeal cavity} = voice box region. - \textbf{Alveolar ridge} = behind upper teeth. - \textbf{Labial cavity} = lips region.

Answer 1

The Correct Option is A

Step 1: Identify the numbered parts in the diagram
- Part 1 → Located at the throat region, behind the oral cavity → Pharyngeal cavity (b).
- Part 2 → Situated deep in the throat near the vocal folds → Laryngeal cavity (d).
- Part 3 → Just behind the upper teeth ridge → Alveolar ridge (c).
- Part 4 → At the lips/front of the mouth → Labial cavity (a).
Step 2: Match with the given labels
Thus, we get the correspondence: 1 → b, 2 → d, 3 → c, 4 → a. Step 3: Verify with options
Option (A) exactly matches this mapping. \[ \boxed{Correct Answer: (A)} \]
