Correct Answer
Here are the correct answers highlighted in the image:
Q21. The upper respiratory tract includes:
✅ cavum nasi, pars nasalis et pars oralis pharynges
The upper respiratory tract consists of the nasal cavity (cavum nasi) and the nasopharynx + oropharynx (pars nasalis et pars oralis pharyngis). The larynx marks the boundary where the lower tract begins, so options including "larynx" are incorrect for the upper tract.
Q22. The lower respiratory tract includes:
✅ larynx, trachea, bronchi
The lower respiratory tract begins at the larynx and continues through the trachea, bronchi, bronchioles, and alveoli. Options listing "pharynx" are wrong (pharynx is upper tract), and options omitting the trachea are incomplete.
Q23. Parts of the external nose:
✅ radix nasi, dorsum nasi, apex nasi (visible at the bottom, highlighted in yellow)
The external nose consists of:
- Radix nasi – root (where the nose meets the forehead)
- Dorsum nasi – bridge/dorsum
- Apex nasi – tip
- Alae nasi – wings/nostrils
- Corpus nasi – body
The highlighted answer at the bottom of the image confirms: radix nasi, dorsum nasi, apex (nasi).
