Answer to Problem 1DYKB

Correct answer:

Nasal septum is formed by two bones; vomer and perpendicular plate of the ethmoid bone. Therefore, option a. is correct.

Explanation of Solution

Reason for the correct statement:

Option a. is given as “perpendicular plate of the ethmoid bone and vomer”. Nasal septum contains hyaline cartilage and bone. The nasal septum is made up of five structures. These structures include vomer bone, perpendicular plate of ethmoid bone, septal nasal cartilage, crest of maxillary and palatine bone. Hence, the two bones that form the nasal septum are vomer and perpendicular plate of ethmoid bone.

Hence, option a. is correct.

Reasons for the incorrect statements:

Option b. is given as “perpendicular plate of the ethmoid bone only”. Nasal septum is also formed from vomer bone. Hence, option b. is incorrect.

Option c. is given as “nasal bones and perpendicular plate of the ethmoid bone”. There are no nasal bones in nasal septum. Hence, option c. is incorrect.

Option d. is given as “vomer and sphenoid bones”. Sphenoid bones do not form the nasal septum. Hence, option d. is incorrect.

Hence, options b., c., and d. are incorrect.

Conclusion

The nasal septum is made up of vomer bone, perpendicular plate of ethmoid bone, septal nasal cartilage, crest of maxillary and palatine bone.
