1
Q

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

A

4 segments

2
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

3
Q

What feature is present at the top of the manubrium sterni?

A

Jugular notch (suprasternal notch)

4
Q

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

A

Clavicular notch

5
Q

What names are given to the articular sites for the joint with the first and second rib?

A

Costal notch I for the first rib costal cartilage; Costal notch II for the second rib costal cartilage

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

8
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 features 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

The head, neck, and tubercle

typical rib = 3-9

11
Q

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

A

Two articular surfaces and the interarticular crest

12
Q

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

A

The 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

The articular surface of the tubercle

16
Q

What is present on the head of the 1st rib?

A

A single articular surface

17
Q

What is lacking at the head of the first rib?

A

The 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 (corpus or shaft) of the first rib?

A

The body (corpus or shaft) of the first rib 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 (corpus or shaft) of the first rib is close to the vertebral end?

A

The groove for the subclavian artery and the first thoracic nerve

21
Q

Which groove on the body (corpus or shaft) of the first rib is close to the sternal end?

A

The groove for the subclavian vein

22
Q

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

A

Two articular surfaces and the interarticular crest

23
Q

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

A

The interarticular crest

24
Q

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

A

The crest of the rib

25
Q

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

A

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

26
Q

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

A

The articular surface of the tubercle

27
Q

What distinguishes the vertebral end of the 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, and the tubercle is absent

29
Q

What is the condition of the body (corpus or shaft) of rib 12?

A

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