29
oval processes with convex surfaces, with one on each side of the foramen magnum.
Two lateral condylar portions (occipital condyles)
30
– two-part articulation between the skull and the cervical spine.
Atlanto-occipital joint
31
The occipital bone articulates with six bones:
PAST Two parietal bones * Two temporal bones * Sphenoid * Atlas (C1)
32
Complex structures that house the delicate organs of hearing and balance.
Temporal Bones
33
It is situated between the greater wing of the sphenoid bone anteriorly and the occipital bone posteriorly.
Temporal Bones
34
an arch of bone extending anteriorly from the squamous portion of the temporal bone.
Zygomatic process
35
concave depression that receives the mandibular condyle of the jaw.
Temporomandibular fossa
36
It is inferior to the zygomatic process and anterior to the EAM.
Temporomandibular fossa
37
formed by the articulation of the mandibular condyle with the temoporomandibular fossa.
Temporomandibular joint
38
a slender bony projection projecting inferior to the mandible and anterior to the EAM.
Styloid process
39
a thin upper portion that forms part of the wall of the skull.
Squamous portion
40
area posterior to the EAM with a prominent mastoid process.
Mastoid portion
41
Petrous portion - also called as
petrous pyramid or pars petrosa
42
houses the organs of hearing and equilibrium, including the mastoid air cells.
Petrous portion
43
thickest and densest bone in the cranium.
Petrous portion
44
upper border or ridge of the petrous pyramids. It corresponds to the level of TEA.
Petrous ridge (petrous apex)
45
an opening or orifice near the center of the petrous pyramid on the posterior surface just superior to the jugular foramen
Internal acoustic meatus
46
to transmit the nerves of hearing and equilibrium.
Internal acoustic meatus
47
Each temporal bone articulates with three cranial bones:
SOP * Parietal bone * Occipital bone * Sphenoid
48
Each temporal bone also articulates with two facial bones:
ZM Zygoma * Mandible
49
Anterior fontanel
Bregma
50
Posterior fontanel
Lambda
51
Right sphenoid fontanel
Right pterion
52
Left sphenoid fontanel
Left pterion
53
Right mastoid fontanel
Right asterion
54
Left mastoid fontanel
Left asterion
55
certain regions where sutures join are slower in their ossification, and these are called
fontanels.
56
separates the frontal bone from the two parietal bones.
Coronal suture
57
separates the two parietal bones in the midline.
Sagittal suture
58
separates the two parietal bones from the occipital bone.
Lambdoidal suture
59
formed by the inferior junctions of the two parietal bones with their respective temporal bones.
Squamosal sutures
60
The articulations or joints of the cranium are called
sutures
61
suture are classified as
fibrous joints.
62
It lies primarily below the floor of the cranium.
Ethmoid Bone
63
small upper horizontal portion of the bone that contains many small openings or foramina through which segmental branches of the olfactory nerves pass
Cribriform plate
64
projecting superiorly from the cribriform plate
Crista galli (rooster’s comb)

projecting downward in the midline which helps to form the bony nasal septum.
Perpendicular plate
66
suspended from the undersurface of the cribriform plate on each side of the perpendicular plate.
Two lateral labyrinths (masses)
67
contain the ethmoid air cells or sinuses and help to form the medial walls of the orbits and the lateral walls of the nasal cavity.
Two lateral labyrinths (masses)
68
thin, scroll-shaped projections of bone that extend medially and downward from the medial wall of each labyrinth.
Superior and middle nasal conchae (turbinates)
69
The ethmoid articulates with two cranial bones:
FS * Frontal bone * Sphenoid
70
Ethmoid also articulates with eleven facial bones:
alll Except mandible Right & left maxillae * Right & left lacrimal bones * Right & left nasal bones * Right & left palatine bones * Right & left inferior nasal conchae * Vomer
71
It forms the anchor for all eight cranial bones.

central depression on the body that looks like a saddle from the side.
Sella turcica (Turkish saddle)
74
the back of the saddle that is best seen on a lateral view.
Dorsum sellae
75
a shallow depression that begins on the posteroinferior aspect of the dorsum sellae of the sphenoid bone and extends posteriorly to the foramen magnum at the base of the occipital bone.
Clivus
76
smaller pair, triangular and are nearly horizontal, ending medially in the two anterior clinoid processes
Lesser wings
77
extend laterally from the sides of the body and form a portion of the floor of the cranium and a portion of the sides of the cranium.
Greater wings
78
