Ribs Flashcards
Typical
3-9 Similar in structure Each rib head to 2 facets Costotransverse articulation
Atypical
1, 2, 10, 11, 12 #1 –most curved, flat, no angle or groove, single facet with vertebral body #2 –demifacetswith T1 & T2 bodies, structure similar to #1 #10 –single facet with T10 body #11 & 12 –no tubercles, tapered ends, single facets w/ bodies (no costotransversearticulatios)
True
1-7 Attaches to sternum directly
False
8-10 Cartilage unites w/ that of rib 7 to attach to the sternum
Floating
11-12 Lack cartilage Float freely w/ muscle fibers
Pump Handle
Ribs 1-5 Transverse processes extend laterally Creates more of a TRANSVERSE AXISBucket
Bucket Handle
Ribs 6-10 Transverse processes angle back (posteriorly) Creates more of an AP AXIS
Caliper
Ribs 11 and 12 Vertical Axis (more or less)

The ribs attach to the vertebral segments at the same level and
above (for example, rib 3 attaches at T2 and T3).
