Q11 / 200 · MHT CET - Medical 2026 (25 April Shift 2) · Biology
In the given diagram, what should be P, Q, R and S respectively?
- Correct answerAHyoid bone, Thyroid cartilage, Epiglottis, Trachea
- BEpiglottis, Cricoid cartilage, Hyoid bone, Trachea
- CEpiglottis, Larynx, Hyoid bone, Bronchus
- DThyroid cartilage, Cricoid cartilage, Epiglottis, Trachea
Solution
Based on the anatomical structure of the human respiratory system shown in the diagram:
P points to the U-shaped bone located above the larynx, which is the hyoid bone.
Q points to the large, shield-shaped cartilage forming the anterior wall of the larynx (often called the Adam's apple), which is the thyroid cartilage.
R points to the leaf-shaped cartilaginous flap that covers the glottis during swallowing, which is the epiglottis.
S points to the tube extending downwards from the larynx, supported by C-shaped cartilaginous rings, which is the trachea.
Therefore, P, Q, R, and S are Hyoid bone, Thyroid cartilage, Epiglottis, and Trachea respectively.
Answer: Hyoid bone, Thyroid cartilage, Epiglottis, Trachea
P points to the U-shaped bone located above the larynx, which is the hyoid bone.
Q points to the large, shield-shaped cartilage forming the anterior wall of the larynx (often called the Adam's apple), which is the thyroid cartilage.
R points to the leaf-shaped cartilaginous flap that covers the glottis during swallowing, which is the epiglottis.
S points to the tube extending downwards from the larynx, supported by C-shaped cartilaginous rings, which is the trachea.
Therefore, P, Q, R, and S are Hyoid bone, Thyroid cartilage, Epiglottis, and Trachea respectively.
Answer: Hyoid bone, Thyroid cartilage, Epiglottis, Trachea
Hence, the correct answer is option: 'A'.
