Which suture connects the frontal bone to the two parietal bones?
Answer: Coronal suture
The coronal suture runs transversely across the skull, joining the frontal bone anteriorly to both parietal bones.
The external occipital protuberance is a landmark on which cranial vault bone?
Answer: Occipital bone
The external occipital protuberance is a prominent midline projection on the outer surface of the occipital bone.
Which part of the temporal bone contains the internal acoustic meatus?
Answer: Petrous part
The petrous part of the temporal bone contains the internal acoustic meatus, through which CN VII and CN VIII pass.
The bregma is the point where which two sutures intersect?
Answer: Coronal and sagittal sutures
Bregma is the junction of the coronal and sagittal sutures, corresponding to the anterior fontanelle in infants.
Which cranial vault bone articulates with all other cranial bones?
Answer: Sphenoid bone
The sphenoid bone articulates with all other cranial bones, earning it the designation as the 'keystone' of the cranium.
The lambda is the junction of the sagittal suture with which other suture?
Answer: Lambdoid suture
Lambda is where the sagittal suture meets the lambdoid suture, overlying the posterior fontanelle in infants.
Which layer of the calvaria is the primary site of diploic veins?
Answer: Diploë
Diploic veins run within the diploë, the spongy cancellous bone sandwiched between the outer and inner tables of the calvaria.
