Question 8

– the largest portion of the
cranium.

Answer 8

Parietal Bone

Question 9

four cranial
bones:

Answer 9

Question 10

2 main parts of frontal bone

Answer 10

Squamos or vertical portion
Orbital or horizontal portion

Question 11

portion- which forms
the forehead

Answer 11

squamous or
vertical

Question 12

portion-which forms
the superior part of the orbit

Answer 12

orbital or
horizontal

Question 13

is the smooth, raised
prominence between the eyebrows
just above the bridge of the nose

Answer 13

Glabella-

Question 14

is
the slight depression above each
eyebrow. Becomes an important
landmark because it corresponds
to the floor of the anterior fossa of the cranial vault, which
is also at the level of the orbital
plate or at the highest level of the
facial bone mass

Answer 14

Supraorbital groove (SOG)

Question 15

superior
rim of each orbit

Answer 15

Supraorbital Margin-

Question 16

is a small hole or opening within
the SOM slightly medial to its
midpoint. The supraorbital nerve
and artery pass through this small
opening.

Answer 16

Supraorbital notch (foramen)

Question 17

rounded prominence On each side
of the squamous portion of the
frontal bone above the SOG

Answer 17

Frontal tuberosity (eminence)

Question 18

As can be seen from the inferior
aspect, the frontal bone shows
primarily the horizontal or orbital
portion (Fig. 11-7), which consists
of the SOM, superciliary ridges
glabella and frontal
tuberosities

Answer 18

Orbital or horizontal portion

Question 19

• inferoposterior part of the cranium.
• This is where the Foramen Magnum is located.
• Articulates with Atlas through Atlanto-Occipital
  Joint.
• Articulates with 5 cranial bones.

Answer 19

Occipital Bone
