The head, neck, and tubercle

2

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

Two articular surfaces and the interarticular crest

3

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

The interarticular crest

4

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

The crest of the rib

5

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

6

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

The articular surface of the tubercle

7

What is present at the head of the first rib?

A single articular surface

8

What is lacking at the head of the first rib?

The interarticular crest

9

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

Not a well-developed on like on a typical rib

10

What is unique about the body (corpus or shaft) of the first rib?

The body (corpus or shaft) of the first rib is flattened and has a scalene tubercle flanked by the groove for subclavian artery and the groove for the subclavian vein

11

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

The groove for the subclavian artery and the first thoracic nerve

12

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

The groove for the subclavian vein

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

The crest of rib 2

16

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

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

17

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

The articular surface on the tubercle

18

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 consist only of a non articular surface

19

What helps to distinguish the vertebral end of the twelfth rib from other ribs?

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

20

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

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