FRONTAL BONES & PARIETAL BONES Flashcards
part of the skull that encloses the brain.
It is also referred to as the
“Calvarium/Calvaria” or Brain case.
CEREBRAL CRANIUM
8 BONES IN CEREBRAL CRANIUM
FOPEST 112 112
are special interlocking joints
between the various bones of the Cerebral
Cranium.
SUTURES
is the region
where the
frontal, sphenoid, parietal
and temporal bones join
together.
Pterion
is the
intersection of parietal,
temporal and occipital
bones.
Asterion
This single bone forms the
forehead and part of the
roof of the skull.
It’s smooth part forms the
forehead;
It’s orbital parts form the
roof of the orbits;
And nasal parts help to
form the nasal cavities.
FRONTAL BONE
Are the ridges forming the
upper margins of the
circular openings of the
orbits.
SUPRA ORBITAL
BORDERS/SUPRA
ORBITAL MARGINS
Is a smooth, rounded bony
prominence above the
nose.
It lies between the supra
-
orbital borders of the
frontal bone.
GLABELLA
Are paired cavities in the squamous or
forehead part of the frontal bone, one on
each side.
They communicate with the nose and vary in
size and/or maybe absent.
FRONTAL SINUSES (2)
Is the middle point of the FrontoNasal suture.
NASION
Lies towards the medial end of each
supra-orbital border.
SUPRA-ORBITAL NOTCH/SUPRA
ORBITAL FORAMEN.
Are paired bones, one on each side of the
Cerebral Cranium.
Forms the lateral wall and part of the roof of
the skull
PARIETAL BONES (2)
is a bony prominence on the
outer surface of each parietal bone which is the
greatest transverse diameter of the skull
