19
Q

what are fontanels?

A

Areas of fibrous connective tissue that connect bones of cranium that allow for distortion of skull during birth

20
Q

anterior

lies at the intersection of the frontal, sagittal, and coronal sutures

21
Q

A

the junction between squamous and coronal sutures

23
Q

______ spinal curves develop before birth and ________spinal curves develop after birth

A

Primary

Secondary

24
Q

What are the 2 primary and the 2 secondary spinal curvatures?

A
Primary:
thoracic
sacral
Secondary:
cervical 
lumbar
25
describe the cervical curve
develops as the infant learns to balance the weight of the head on the vertebrae of the neck
26
describe the thoracic curve
accommodates the thoracic organs
27
describe the lumbar curve
balances the weight of the trunk over the lower limbs; it develops with the ability to stand
28
describe the sacral curve
accommodates the abdominopelvic organs
29
how many cervical, thoracic, and lumbar vertebra are there?
cervical=7 thoracic=12 lumbar=5
30
what are the names for c1 and c2
c1=atlas | c2=axis
31
how many pairs of "true" ribs are there? | what is the other name for these?
7 (1-7); vertebrosternal | *attach directly to the sternum
32
how many pairs of "false" ribs are there? | what is the other name for these?
3 (8-10); vertebrochondral | *do not attach directly to the sternum; fuse together before reaching the sternum
33
how many pairs of "floating" ribs are there? | what is the other name for these?
2 (11-12); Vertebral | *have no connection with the sternum
