Q

Chondrocranium

A

Base of the skull

17
Q

Neurocranium derm layers

A

From neural crest cell (ectoderm)

Somitomeres (mesoderm)

18
Q

Viscerocranium cells

A

Face

Entirely neural crest cells (ectoderm)

19
Q

Neural crest cells

A

Freely migrate and carry genetic code for development

20
Q

Viscerocranium bones (9)

A 
All neural crest cells: 
Facial bones 
Mandible 
Maxilla 
Zygoma
Vomer 
Palatine 
Lacrimal 
Nasal 
Conchae
21
Q

Neurocranium

Which cells make which bones

A 
Neural crest cells:
Temporal (squamosal) 
Sphenoid 
Ethmoid 
Frontal bones

Mesoderm:
Temporal (petrosal)
Occipital
Parietal

22
Q

All bone are mesoderm except

A 
Viscerocrainium
Temporal 
Sphenoid 
Ethmoid 
Frontal bones 
Hyoids
23
Q

Cartilage development starts at

A

Midline

24
Q

Chondrocranium

A

Cranial base

Part occipital 
Ethmoid 
Sphenoid 
Temporal 
Meckel's cartilage
25
Q

Intramembranous ossification

A

Absence of cartilage model

Flat bones of face and skull
Maxilla
Mandible
Clavicle

26
Q

Endochondral ossification

A

Cartilage model precursor

Long bones 
Bones of extremities
Vertebrae 
Ethmoid 
Sphenoid 
Chondrocranium (cranial base)
27
Q

Embryonic bone development process

A

Intramembranous

Endochondral

28
Q

Intramembranous ossification steps

A
  1. Mesenchymal cells proliferate
  2. Mesenchymal cells differentiate into osteoblasts secreting osteoid at multiple centers of ossification

3 osteoid is mineralized

29
Q

Endochrondral ossification steps to

A

Hyaline cartilage model is used as a template

  1. Mesenchymal osteoblasts for two ossification centers
  2. Osteoid deposited in place of cartilage model

Usually ,make long bone

30
Q

Epiphyseal cartilage has Distinct zones

A

5, for endochondral bone growth

31
Q

Sutures and fontanelles

A

Allow for expansion for brain and allows for passage through the birth canal

32
Q

How many fontanelles are there

A

6

Unfused sutures

33
Q

How many bones does a newborn have?

A

44

34
Q

Cranioschisis

A

Cranial vault does not form

Brain is fine

35
Q

Craniosynostosis

A

Premature closure of one or more cranial sutures (suture fails)

36
Q

Scaphocephaly

A

Craniosynostosis

Sagittal suture fails

Expansion of the frontal and occipital bone (long and narrow)

37
Q

Brachycephaly

A

Craniosynostosis

Coronal sutures fails

Skull grows outward (stout skull)

38
Q

Plagiocephaly

A

Craniosynostosis

Unilateral
coronal and lambdoid sutures

Asymmetric flattening of one side of skull

39
Q

Cloverleaf skull

A

Craniosynostosis

Cloverleaf skull: most cranial sutures
