1

What is the skeleton of the head

Cranium (skull)

2

The cranium consists of two parts:

Neurocranium and viscerocranium

3

The Neurocranium is divided into two parts:

Calvaria (skullcap) and cranial base (floor of skull)

4

The neurocranium is formed by ___ (#) bones

8 bones, 4 singular bones located on the midline (frontal, ethmoid, sphenoid, and occipital) and 2 sets occurring as bilateral pairs (temporal and parietal)

5

The viscerocranium form the ____ part of the cranium and consists of ___ (#) irregular bones

Anterior, 14 (2 singular bones lying in the midline (vomer and mandible) and 6 paired occurring bilaterally (maxilla, inferior nasal concha, zygomatic, palatine, nasal, and lacrimal bones)

6

Forms the skeleton of the forehead, articulating with the nasal and zygomatic arches

Frontal bone

7

Forms the roof of the orbit and part of the floor of the anterior part of cranial cavity

Frontal bone

8

Intersection of the frontal and nasal bones

Nasion

9

Supra-orbital margin, Supra-orbital foramen, supercillary arch are located on the

Frontal bone

10

Smooth area between the supercillary arches

Glabella

11

Lie on inferolateral sides of the orbits and rest on the maxillae

Zygomatic bones

12

Pierces the lateral aspect of each bone

Zygomaticofacial foramen

13

Articulate with each other in the midline, with the frontal bone superiority

Nasal bones

14

Anterior nasal opening of the cranium

Piriform aperture

15

Formed by dividing nasal cavity into left and right parts

Nasal septum

16

Paired conchae visible through the nasal aperture

Inferior nasal conchae

17

Maxillae is united at the _____ _____ in themedian plane

Intermaxillary suture

18

Support bone for the maxillary teeth

Maxillae alveolar processes

19

Maxillae connects with zygomatic bones laterally and have _____________ ________ inferior to each orbit

Infra-orbital foramen

20

Laterally articulates with the zygomatic bone and medially articulates with the frontal bone

Maxillae

21

Forms the chin (horizontal portion)

Body of mandible

22

Vertical extension of the body on either side

Ramus of mandible

23

Articulation point of mandible with the mandibular fossa of the temporal bone

Condyle

24

Anterior portion of the Ramus, site for muscle attachment on mandible

Coronoid process

25

Posterior point at which Ramus meets the body of the mandible

Angle

26

Between 1st and 2nd premolars

Mental foramen

27

Located on the medial aspect of mandibular Ramus

Mandibular foramen

28

This foramen permits passengers of the nerve involved with tooth sensation

Mandibular foramen

29

The region where the two halves of the mandible fuse

Mandibular symphysis

30

Passing from inferior of the Ramus onto the body of mandible

Oblique line
