Sample Face, Nose & Palate, Eye, Ear MCQs with answers
Sample MCQ #1
Many facial malformations are believed to be due to:
AA failure of the oral membrane to rupture
BA failure of neural crest cells to migrate into the facial processes
CA failure in growth of the head fold
DAn abnormal persistence of the pharyngeal clefts
Show Answer & Explanation ▾
✓ Correct Answer: B. A failure of neural crest cells to migrate into the facial processes
Proper migration of neural crest cells into the face area is vitally important to facial development. Neural crest tissue will form much of the facial skeleton. Reference - Textbook of Langman's, 12th Edition, Head and Neck Embryology Page number - 275
Sample MCQ #2
Identify the correct associations:
APrimary palate - palatine shelves of maxillary processes
BNeural crest cells - facial processes
CNasolacrimal groove - lateral nasal process and mandibular process
DCleft lip - medial & lateral nasal processes
Show Answer & Explanation ▾
✓ Correct Answer: B. Neural crest cells - facial processes
The primary palate arises from the intermaxillary segment. Neural crest cells are vital to the development of the facial swellings. The nasolacrimal groove separates maxillary and lateral nasal swellings. Cleft lip can result from failure of fusion between the maxillary and medial nasal prominences.

Sample MCQ #3
The membranous labyrinth develops from which structure?
AFirst pharyngeal pouch
BFirst pharyngeal cleft
COtic vesicle
DMeckel's cartilage
Show Answer & Explanation ▾
✓ Correct Answer: C. Otic vesicle
The membranous labyrinth of the internal ear is derived from the otic vesicle. The surface ectoderm on either side of the hindbrain thickens to form otic placodes. The otic placodes invaginate to form otic vesicles (auditory vesicles). Reference - Textbook of Langman's, 12th Edition, Head and Neck Embryology Page number - 268
Sample MCQ #4
As a resident in pediatrics, you are called to see a newborn who has a unilateral cleft lip and a unilateral cleft of the primary palate. This condition is most likely the result of:
AFailure of fusion of the mandibular prominences
BFailure of fusion of the medial nasal processes
CFailure of fusion of the maxillary prominence with the medial nasal prominence
DFailure of fusion of the lateral palatine processes with the nasal septum
Show Answer & Explanation ▾
✓ Correct Answer: C. Failure of fusion of the maxillary prominence with the medial nasal prominence
This type of cleft is a failure of fusion, or secondary rupture of the union, of maxillary prominence with medial nasal prominence. If the palatine shelves or processes of maxillary prominences rupture or fail to fuse, a midline defect of the secondary palate will result.

Sample MCQ #5
An absent lower jaw is called:
AMicrognathus
BCleft lip
CMacrostomus
DAgnathus
Show Answer & Explanation ▾
✓ Correct Answer: D. Agnathus
The total absence of a lower jaw is termed agnathus. There is a class of fishes called agnatha with no lower jaw development. Reference - Textbook of Langman's, 12th Edition, Head and Neck Embryology Page number - 278
Sample MCQ #6
The otic vesicle does NOT develop into the:
AMembranous cochlea
BEndolymphatic duct
CSaccule
DOtic placode
Show Answer & Explanation ▾
✓ Correct Answer: D. Otic placode
Otic vesicle develops into the saccule, cochlear duct or membranous cochlea, utricle, semicircular canals and endolymphatic duct & sac. It develops FROM the ectodermal otic placode. Reference - Textbook of Langman's, 12th Edition, Ear Embryology Page number - 321
Sample MCQ #7
From which structures do the alae of the nose develop?
AFrontonasal process
BMedial nasal process
CLateral nasal process
DBucconasal membrane
Show Answer & Explanation ▾
✓ Correct Answer: C. Lateral nasal process
The alae of the nose develop from the lateral nasal processes. The development of various components of the nose can be summarized as follows: Bridge - The frontonasal process Dorsum and tip - Fused medial nasal processes Alae - The lateral nasal processes Anterior nares (nostrils) - The original site of the nasal pit Reference - Textbook of Langman's, 12th Edition, Head and Neck Embryology Page number - 268
Sample MCQ #8
Which structures are derived from the optic cup?
ANeural retina
BIris epithelium
CPigment layer of the retina
DAll of the above are correct
Show Answer & Explanation ▾
✓ Correct Answer: D. All of the above are correct
The optic cup ultimately develops into the pigment layer of the retina, the neural retina, the epithelium of the iris and the epithelium of the ciliary body. Reference - Textbook of Langman's, 12th Edition, Head and Neck Embryology Page number - 268
