A

clavicular notch

3
Q

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

A

costal notch I for first rib costal cartilage

costal notch II for 2nd rib costal cartilage

4
Q

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

A

4 segments

5
Q

what bony features are present on the coccyx?

A

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

6
Q

how many sternabrae for the corpus sterni?

A

4 sternabrae

7
Q

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

A

transverse lines

Q

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

A

costal notches II-VII

9
Q

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

A

a sternal foramen

10
Q

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

A

head, neck and tubercle

11
Q

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

A

2 articular surfaces and an interarticular crest

12
Q

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

A

interarticular crest

13
Q

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

A

the crest of the rib

14
Q

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

A

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

15
Q

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

A

articular surface of the tubercle

16
Q

what is present on the head of the first rib?

A

a single articular surface

17
Q

what is lacking at the head of the first rib?

A

interarticular crest

18
Q

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

A

not a well-developed one like on the typical rib

19
Q

what is unique about the body of the first rib?

A

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

20
Q

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

A

groove for the subclavian artery and 1st thoracic nerve

21
Q

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

groove for the subclavian vein

22
Q

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

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

A

articular surface of the tubercle

27
Q

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

A

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
Q

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

A

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

29
Q

what is the condition of the body of rib 12?

A

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