1

what feature is present at the top of the manubrium stern?

jugular notch (suprasternal)

2

what is the name given to the articular site at the superolateral margin of the manubrium sterni?

clavicular notch

3

what names are given to the articular sites for the joint with the 1st and 2nd rib?

costal notch I for first rib costal cartilage
costal notch II for 2nd rib costal cartilage

4

what is the typical number of segments that unite to form the adult coccyx?

4 segments

5

what bony features are present on the coccyx?

all segments are represented by a "vertebral body" in addition, Co1 has a coccygeal cornu and transverse process

6

how many sternabrae for the corpus sterni?

4 sternabrae

7

what surface feature on the corpus sterni identifies the location of the old synchondroses?

transverse lines

8

what articular sites for the costal cartilage of ribs will be identified on the corpus sterni?

costal notches II-VII

9

what feature of the corpus sterni is present in 4-7% of the population?

a sternal foramen

10

what are the primary parts of the vertebral end of a typical rib?

head, neck and tubercle

11

what features may be identified on the head of a typical rib?

2 articular surfaces and an interarticular crest

12

what feature of the head of a rib separates the superior from the inferior articular surface/facet?

interarticular crest

13

what features may be identified on the neck of a typical rib?

the crest of the rib

14

what features may be identified on the tubercle of a typical rib?

the articular surface of the tubercle and the non-articular surface of the tubercle

15

which feature of the tubercle of a typical rib is closer to the head of the rib?

articular surface of the tubercle

16

what is present on the head of the first rib?

a single articular surface

17

what is lacking at the head of the first rib?

interarticular crest

18

is there a crest on the neck of the first rib?

not a well-developed one like on the typical rib

19

what is unique about the body of the first rib?

it is flattened and has a scalene tubercle flanked by the groove for the subclavian artery and the groove for the subclavian vein

20

which groove on the body of the 1st rib is close to the vertebral end?

groove for the subclavian artery and 1st thoracic nerve

21

which groove on the body of the 1st rib is close to the sternal end?

groove for the subclavian vein

22

what features may be identified on the head of rib 2?

2 articular surfaces and an interarticular crest

23

what feature on the head of rib 2 separates the superior from inferior articular surface/facet?

interarticular crest

24

what feature may be identified on the neck of rib 2?

crest of the rib

25

what features may be identified on the tubercle of rib 2?

articular surface of the tubercle and non-articular surface of the tubercle

26

which feature of the tubercle of rib 2 is closer to the head of the rib?

articular surface of the tubercle

27

what distinguishes the vertebral end of rib 11 from typical ribs?

the single articular surface, absence of a well-developed crest on the neck and the tubercle may be absent or if present, consists only of a non-articular surface

28

what helps to distinguish the vertebral end of the 12th rib from other ribs?

the head has a single articular surface, the crest of the neck is poorly developed, tubercle is absent

29

what is the condition of the body of rib 12?

costal angle and costal groove are absent and it is the shortest of all ribs
