Question
Which of the following is NOT one of the six cranial bones?

A) Frontal
B) Temporal
C) Mandible
D) Sphenoid

Expert Rationale: The six cranial bones are the frontal, temporal, ethmoid, parietal,
occipital, and sphenoid. The mandible is a facial bone, not a cranial bone. Cranial bones
form the cranial cavity that protects the brain.



Question
Which cranial bone is described as the "batwing" shaped bone?

A) Frontal
B) Sphenoid
C) Ethmoid
D) Occipital

Expert Rationale: The sphenoid bone is often described as "batwing" shaped due to its
central body and paired greater and lesser wings. It is a key bone at the base of the skull
and articulates with many other cranial bones.



Question
Which suture is formed by the frontal and parietal bones?

,A) Sagittal suture
B) Coronal suture
C) Lambdoidal suture
D) Squamosal suture

Expert Rationale: The coronal suture is formed by the frontal and parietal bones. It runs
horizontally across the top of the skull, separating the frontal bone from the two parietal
bones.



Question
Which suture is formed by the two frontal bones?

A) Sagittal suture
B) Coronal suture
C) Frontal (metopic) suture
D) Lambdoidal suture

Expert Rationale: The frontal (metopic) suture is formed by the two frontal bones. It is
present in infants and typically fuses by age 6-8 years. Persistence of this suture can result
in a prominent forehead.



Question
Which suture is formed by the occipital and parietal bones?

A) Coronal suture
B) Sagittal suture
C) Lambdoidal suture
D) Squamosal suture

Expert Rationale: The lambdoidal suture is formed by the occipital and parietal bones. It
runs horizontally across the back of the skull and is shaped like the Greek letter lambda (λ).



Question
Which suture is formed by the two parietal bones?

A) Coronal suture
B) Sagittal suture

,C) Lambdoidal suture
D) Squamosal suture

Expert Rationale: The sagittal suture is formed by the two parietal bones. It runs
longitudinally along the top of the skull, from the coronal suture to the lambdoidal suture.



Question
Which suture is formed by the temporal and parietal bones?

A) Coronal suture
B) Sagittal suture
C) Lambdoidal suture
D) Squamosal suture

Expert Rationale: The squamosal suture is formed by the temporal and parietal bones. It is
located on the side of the skull and has a beveled, overlapping appearance.



Question
What is craniosynostosis?

A) Premature fusion of the lambdoidal, coronal, and sagittal sutures
B) Delayed fusion of all sutures
C) Absence of sutures
D) Overgrowth of the skull

Expert Rationale: Craniosynostosis is the premature fusion of the lambdoidal, coronal,
and sagittal sutures. It may lead to microcephaly and secondary microcephaly. Surgical
intervention is often required.



Question
What is a cloverleaf skull?

A) Premature fusion of the coronal and lambdoidal sutures resulting in a trilobed skull
appearance
B) Premature fusion of the sagittal suture only
C) Delayed fusion of all sutures
D) Normal variant of the skull

, Expert Rationale: Cloverleaf skull is a severe form of craniosynostosis caused by
premature fusion of the coronal and lambdoidal sutures. It results in a trilobed skull
appearance. Children with this condition often die in infancy and have profound mental
deficiencies.



Question
Where is the anterior fontanelle located?

A) Junction of the 2 parietal bones and occipital bone
B) Junction of the 2 frontal bones and 2 parietal bones
C) Junction of the temporal, parietal, and occipital bones
D) Junction of the frontal, parietal, temporal, and sphenoid bones

Expert Rationale: The anterior fontanelle is located at the junction of the 2 frontal bones
and 2 parietal bones. It is the largest fontanelle and typically closes between 12-18 months
of age.



Question
Where is the posterior fontanelle located?

A) Junction of the 2 frontal bones and 2 parietal bones
B) Junction of the 2 parietal bones and the occipital bone
C) Junction of the temporal, parietal, and occipital bones
D) Junction of the frontal, parietal, temporal, and sphenoid bones

Expert Rationale: The posterior fontanelle is located at the junction of the 2 parietal bones
and the occipital bone. It is smaller than the anterior fontanelle and typically closes by 2-3
months of age.



Question
Where is the mastoid fontanelle located?

A) Junction of the 2 frontal bones and 2 parietal bones
B) Junction of the 2 parietal bones and occipital bone
C) Junction of the temporal, parietal, and occipital bones
D) Junction of the frontal, parietal, temporal, and sphenoid bones
