10
Question
What major opening does the occipital bone contain?
Answer
Foramen magnum.
11
Question
What are the parts of the occipital bone?
Answer
Basilar part, squamous part, lateral parts.
12
Question
What is located on either side of the basilar part of the occipital bone?
Answer
Jugular foramen (foramen jugulare) near tympanic bullae.
13
Question
What border do the lateral parts of the occipital bone form?
Answer
Lateral border of the foramen magnum.
14
Question

Answer
Nuchal crest.
15
Question
Where is the external occipital protuberance located?
Answer
Median position at the caudal end of the sagittal crest.
16
Question
What is the parietal bone’s relationship to the frontal bone?
Answer
Parietal joins frontal rostrally and medially; forms dorsolateral calvaria roof.
17
Question
What bone does the parietal bone meet caudally?
Answer
Occipital bone.
18
Question
What is the interparietal bone and its relation to the occipital bone?
Answer
Unpaired bone that fuses with occipital prenatally; appears as rostral extension.
19

Answer
Joins squamous temporal and basisphenoid bones.
20
Question
What bone forms the rostral part of the orbit and its relation to the parietal bone?
Answer
Frontal bone; rostral to parietal bone.
21
Question
What is the external sagittal crest made of?
Answer
Median ridge formed by the parietal and interparietal bones.
22
Question
From where to where do the external sagittal crests extend?
Answer
From the external occipital protuberance to the zygomatic process of the frontal bone.
23
Question
What is the temporal fossa and its borders?
Answer
Convex fossaa on each side of dorsum; bounded medially by sagittal crest/temporal line, caudally by nuchal crest, ventrally by zygomatic process of temporal bone.
24

Answer
Caudoventral part of the lateral skull surface.
28
Question
What is the zygomatic process of the temporal bone?
Answer
Long bony projection; together with zygomatic bone forms the zygomatic arch.
29
Question

Answer
Ventral portion of the temporal fossa and bears a zygomatic process.
30
Question
How does the temporal bone articulate with surrounding bones?
Answer
Dorsally with parietal; rostrally with basisphenoid wing; caudally with occipital.
