Joint

15

what does brachium mean?

upper arm

16

what does antebrachium mean?

lower arm

17

what does costa mean?

rib

18

what does suture mean?

fibrous joint between flat bones of the skull

19

what are fontanels?

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

20

what is the largest fontanel and where is it located?

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

21

where is the posterior fontanel located?

the junction between the lambdoid sutures and the sagittal suture

22

where is the sphenoidal fontanel located?

the junction between squamous and coronal sutures

23

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

Primary
Secondary

24

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

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

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
