2 years, complete ossification at 6 years

9

Blood supply to calvarium

Middle meningeal arteries

10

Layers of SCALP

S- Skin (sweat/sebaceous glands)
C- Connective tissue (well vascularized/innervated)
A- Aponeurosis epicranialis ( galea aponeurotica)
L- Loose connective tissue- allows scalp to be mobile
P- Pericranium (periosteium)

Posterior auricular
Occipital

14

Vertical elongation of the face takes place when

Growth of the maxilla between the ages of 6 and 12

15

facial

16

levator palpebrae superioris is supplied by what

Occulomotor

3 molars

23

What seperates tongue in half

Fibrous lingual septum

24

What are the extrinsic muscles of the tongue

Genioglossus
Hypglossus
Styloglossus
palato- glossus

25

What supplies all the muscles of the tongue except the palato glossus

hypoglossal CN XII Hypoglossal

26

Artery of the tongue

lingual artery

27

Arterial blood supply to the calvarium is mainly

middle meningeal

28

the face is richly supplied with arteries

facial (main supply),
superficial temporal and transverse facial.

29

The intrinsic muscles of the tongue

superior longitudinal (curls the tip and side superiorly making the dorsum concave),

inferior longitudinal (curls the tip inferiorly, making the
dorsum convex),

the transverse (narrows and increases the height of
the tongue)

and the vertical (flattens and broadens the tongue and
acting with the transverse muscle, it increases the length of the tongue).

30

filiform papillae containing taste buds

anterior 2/3 of the tongue
