Introduction :
The nasal septum is a cartilage and bone structure in your nose. The septum separates the nasal cavity into two halves. The septum has "deviated" when it is off-center or leans to one side of the nasal cavity. This is referred to as a deviated nasal septum by doctors.
Answer to Problem 1DYKB
Correct answer :
The correct answer is option (a) perpendicular plate of the ethmoid bone and vomer.
Explanation of Solution
Explanation/justification for the correct answer :
Option (a) perpendicular plate of the ethmoid bone and vomer. The septum's bony portion consists of the ethmoid bone's perpendicular plate, the vomer, and the maxillary crest, which is supported by the maxillary and palatine bones. The septum's caudal portion is formed by quadrangular cartilage. So, the correct answer is option (a).
Explanation for incorrect answer :
Option (b) perpendicular plate of the ethmoid bone only. The nasal septum is formed by combining the vomer and the ethmoid bones. So, this is an incorrect option.
Option (c) nasal bones and perpendicular plate of the ethmoid bone. The nasal bones are two short oblong bones that differ significantly in size and shape depending on the organism. They are placed beside each other in the middle and upper part of the face, and their roundabout aids in the formation of the bridge of the upper one-third of the nose. So, this is an incorrect option.
Option (d) vomer and sphenoid bones. The sphenoid is one of the twenty-two bones that make up the skull and serves to connect the neurocranium to the facial skeleton. So, this is an incorrect option.
