Q

Do the cranial bones articulate in the newborn?

A

No. They do not articulate to allow for passage of the head through the birth canal and accommodate the growth of the brain.

Q

What 7 bones make up the bony orbit?

A

frontal, maxillary, ethmoid, sphenoid, lacrimal, zygomatic and palantine

27
Q

visocranium is

A

face

28
Q

Nares

A

nostrils open up into the nasal cavity which is lined with mucosa

29
Q

lateral wall of the nasal cavity has?

A

bumpy projections which are the conchae (turbinates)

30
Q

The superior and middle conchae are part of which bone?

A

the ethmoid bone

31
Q

The inferior conchae are?

A

individual bones

32
Q

The roof of the nasal cavity contains receptors from which nerve?

A

olfactory nerve

33
Q

The two nostriles are separated by what are the midline?

A

nasal septum.

This consists of the perpendicular plate of the ethmoid, the vomer and cartilage - all of which are covered in mucus

34
Q

What do the conchae do?

A

they warm and filter inhaled air and the mucosa serves and immune function by trapping foreign particles and exposing them to antigen presenting cells

35
Q

sutures are?

A

fibrous joints between the bones of the skull

36
Q

coronal suture

A

between frontal and parietal bones

37
Q

sagaittal suture

A

between parietals

38
Q

lambdoidal suture

A

between parietal and occiput

39
Q

squamosal suture

A

between the parietal and temporal

40
Q

bregma suture

A

junction of the corona and sagittal sutures

41
Q

lamda suture

A

junction b/w the lamdoidal and sagittal sutures

42
Q

pterion suture

A

junction of the frontal, parietal, temporal and sphenoid bones

43
Q

sutural ligaments that connect the cranial bones are the remaining

A

unossified sheets of mesenchyme from intramembranous ossification

44
Q

Muscles of facial expression are innervated by

A

the facial nerve (CN VII)

45
Q

Muscles of facial expression are

A

sphincter muscles: orbicularis oculi, orbicularis oris (they close things off when contracted)
all the other muscles may be considered dilator muscles

46
Q

Muscles of mastication are innervated by?

A

the trigeminal nerve (CN V)

47
Q

What are the muscles of mastication?

A

temporalis, masseter, medial pterygoid, lateral pterygoid

48
Q

What are the movements of the jaw?

A

elevation, depression, protraction and retraction

49
Q

medial ptygoid

A

elevation and protusion

50
Q

lateral ptygoid

A

depression and protrusion

51
Q

temporalis

A

elevation and retraction

52
Q

masseter

A

elevation and protrusion (jut jaw forward)

53
Q

Anterior neck is divided into two regions

A

anterior triangle

posterior triangle

54
Q

anterior triangle of the anterior neck is bordered by

A

the sternocleidomastoid, the inferior border of the mandible and the anterior midline of the neck

55
Q

posterior triangle of the anterior neck is bordered by

A

the sternocleidomastoid, the clavicle and the trapezius

56
Q

What are the 7 muscles of deglutition/speech?

A

57
Q

digastric anterior belly innervated by

A

trigeminal nerve

58
Q

digastric posterior belly innervated by

A

facial nerve

59
Q

mylohyoid innervated by

A

trigeminal nerve

60

A

vagus nerve

63
Q
