Correct Answer � C
Explanation
|
|
External nose involves the upper third being composed of bone, specifically the nasal bones, and the lower two-thirds being formed by various cartilages, including the lateral, alar, and septal cartilages. This design provides both the rigidity and flexibility necessary for the nose’s structural integrity and functionality, making option A the correct answer.
Reasons to rule out other options
A. Upper ½ is bony, and lower 1/2 is cartilaginous: This division doesn’t accurately reflect the structural anatomy of the nose, as the bony part does not make up a full half of the external nose.
B. Upper 2/3rd is bony and the lower 1/3rd is cartilaginous: This option incorrectly suggests that the bony portion occupies a greater portion of the nose than it actually does, overstating the extent of the bony framework.
