Anatomy & Physiology of Nose

Question
15 out of 33
 

External nose is formed from: [AP96]



A 3 paired + 3 unpaired cartilages

B 2 paired + 2 unpaired cartilages

C 3 paired + 4 unpaired

D paired + 1 unpaired

Ans. B 2 paired and 2 unpaired cartilage

External nose is made up of bony framwork which forms upper third part and cartilaginous forms lower two-third part framwork.

Cartilages of nose:

Paired upper lateral nasal cartilages

Paired lower nasal cartilages

Lesser alar (sesamoid) cartilages - 2 or more in number

Unpaired septal cartilage.

For example, there are either 3 paired and 1 unpaired cartilage or 2 paired and 2 unpaired cartilage because lesser alar (or sesamoid) cartilages can be 2 or more. In this question, 2 paired and 2 unpaired cartilage is the more close option and is the answer.
