Articular facets are where…?
Costal facets are where….?
Transverse costal facets are where?
Articular = is where two vertebral bodies meet
Costal = where the ribs connect to the body of the vertebrae
Transverse Costal = is where the TVP meets the rib
The manubriosternal joint is a landmark for what?
rib 2
which ribs are the “True” ribs? why are they called true ribs?
ribs 1-7
Because they have a direct connection with the sternum via their own costal cartilage
Which ribs are the “false “ ribs? why are they called false ribs?
ribs 8-12
Because they have an indirect connection with the sternum via the costal 7th cartilage
Which ribs are the floating ribs? why?
11, 12
because they are not attached to anything anteriorly
if you wanted to find rib 2 on the chest what landmark would you look for?
Manuberiosternal joint (sternal angle)
Which ribs are “typical ribs” and what are the characteristics that make them typical?
2-10
Typical ribs have a …
Head = 2 facets (inf,sup) that articulate with 2 vert bodies
Neck = between the head and the tubercle
Tubercle = articular facet ( articulates with the TVP)
Shaft = angle sharpest curvature of the rib
