occipital bone

24
Q

at the sides of the cranium,
extending inward to form part of the cranial floor.
The left and right forms the lateral walls of the
cranium as well as housing the external ear.

A

temporal bone

25
Q

is a butterfly shaped bone that
forms part of the anterior floor and sides of the
cranium. It forms part of the eye orbit and helps to
form the floor of the cranium.

A

sphenoid bone

26
Q

forms the middle portion of the anterior cranial floor, extending inferiorly between the eye
orbits to also form the roof of the nasal cavity.

A

ethmoid

27
Q

immovable joints between bones of the Skull

A

sutures

28
Q

The parietal bones are joined by the ______________
Parietal bones that meet the frontal is referred to as the

A

sagittal sutures

29
Q

The parietals and the occipital meet at the ____________

A

lambdoidal
suture

30
Q

The suture between the parietals and the temporal
bone is referred to as the __________

A

squamous suture.

31
Q

is the lower jawbone. It articulates with the temporal bones at the temporomandibular joints. This forms the only freely moveable joint in the head. It provides the
chewing motion

A

mandible

32
Q

are the upper jaw
bones. They form part of the nose, orbits, and roof of
the mouth.

A

right and left maxilla

33
Q

form a portion of the
nasal cavity and the posterior portion of the roof
of the mouth.

A

right and left palatine

34
Q

are the cheek bones. They form portions of the orbits as well.

A

right and left zygomatic

35
Q

form the superior portion of the bridge of the nose.

A

right and left nasal

36
Q

help to form the orbits.

A

right and left lacrimal

37
Q

forms part of the nasal septum (the divider between the nostrils)

A

A

left and right inferior nasal conchae

39
Q

The skull is the bony framework of the head. It comprised the eight cranial and fourteen facial
bones.

A

skull

40
Q

Directed to exit the glabella at 10° cephalad
- Midpoint of IR coincides with CR
- Use close collimation

A

Sella Turcica: PA Axial Projection

41
Q

Center the IR to region of sella approximately ¾ “
anterior and ¾” superior to the EAM

A

Sella Turcica: Lateral Projection

42
Q

The success of SMV projection of cranial base depends on placing IOML as nearly parallel with the plane of the IR as possible and directing CR
perpendicular to IOML.

A

Cranial Base: Submentovertical Projection

43
Q

recommended strong depression of the chin and direction of the central through the foramen magnum at a caudal angle of 40 degrees.

A
  • Altschul
44
Q

_______ & _____________ described the position in 1926

A

Altschul and Towne fowler eme

45
Q
  • Perpendicular or 15 degrees cephalad direct to nasion
A

AP & AP Axial projection

46
Q

RP for Lateral Projection of CRANIUM

A

2 inches superior to EAM

47
Q

-superimposed halves of the cranium
- sella turcica, anterior and posterior clinoid
processes, dorsum sella

A

CRANIUM: Lateral Projection

48
Q

angulation for PA Axial Proj (Caldwell Method)

A
  • 15 degrees caudal to exit nasion.
49
Q

recommended that with the patients’ chin depressed, the central ray should be directed through MSP from a point 3” above the eyebrow to the foramen magnum with no specific angulation but depending on the flexion of the neck

A

Towne (Fowler)

50
Q

CR: 37 degrees caudal to the IOML

A

Ap Axial Projection (Towne)

51
Q

devised this position for obtaining an image of the sellar structures projected within the foramen magnum on hypersthenic, obese or other patients
who cannot be adjusted correctly for AP axial Towne
projection

A

PA Axial Projection (HAAS)

52
Q

orbit is filled by margins of Petrous pyramids, posterior ethmoidal air cells, crista galli, frontal bone,
frontal sinuses & dorsum sellae

A

PA Axial projection (Caldwell)

53
Q

CR of Verticosubmental Projection (Schuller Method)

A

Perpendicular to IOML passing ¾ “ anterior to EAM centered to sella turcica

54
Q

typical cranium/normal or average.
Approximately 47 degrees in relation to
Petrous ridges.

A

Mesocephalic

55
Q

short from front to back. Broad from
side to side. Shallow from vertex to base.
Internal structures are higher with reference to IOML ,approximately 54 degrees in relation
to Petrous ridges

A

side to side. Deep from vertex to base. Internal structures are lower with reference to IOML Approximately 40 degrees in relation to Petrous
ridges.
