Ribs Flashcards
What are the primary pats of the vertebral end of a typical rib?
The head, neck, and tubercle
What features may be identified on the head of a typical rib?
Two articular surfaces and the interarticular crest
What feature of the head of a rib separates the superior the superior from inferior articular surface/facet?
The interarticular crest
What features may be identified on the neck of a typical rib?
The crest of the rib
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
Which feature of the tubercle of a typical rib is closer to the head of the rib?
The articular surface of the tubercle
What is present at the head of the first rib?
A single articular surface
What is lacking at the head of the first rib?
The interarticular crest
Is there a crest on the neck of the first rib?
Not a well-developed on like on a typical rib
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
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
Which groove on the body (corpus/shaft) of the first rib is close to the sternal end?
The groove for the subclavian vein
What features may be identified on the head of rib 2?
Two articular surfaces and the interarticular crest
What feature of the head of rib 2 separates the superior from inferior articular surface/facet?
The interarticular crest
What feature may be identified on the neck of rib 2?
The crest of rib 2
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
Which feature of rib 2 is closer to the head of the rib?
The articular surface on the tubercle
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
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
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
