Human Anatomy and Physiology11th EditionElaine Nicpon Marieb, Lori A. Smith 1,303 solutions How many ribs articulate indirectly with the sternum?Ribs 8–10 are attached indirectly to the sternum. For these ribs, the costal cartilage of each attaches to the cartilage of the next higher rib. The last false ribs (11–12) are also called floating (vertebral) ribs, because these ribs do not attach to the sternum at all.
Which ribs articulate indirectly with the sternum?The false ribs are the ribs that indirectly articulate with the sternum, as their costal cartilages connect with the seventh costal cartilage; by the costochondral joint; They are the eighth, ninth, and tenth ribs.
Do ribs 11 and 12 articulate with the sternum?The floating ribs (11,12) do not articulate with the sternum at all (distal two ribs).
What do ribs 11 and 12 articulate with?Tenth, eleventh, twelfth ribs
The tenth to twelfth ribs have only one facet on their heads, and as such only articulate with a single vertebra. Ribs eleven and twelve in particular are short and have no necks or tubercles.
