Document Summary

True or false rib or float ribs (2) If you have a rib cage in front of you, you can identify rib 3 vs. 4 in comparison. But you usually can"t really identify them on their own. -> the numbering of individual ribs are easy to identify together, not separate. -> you need to see the ribs together, a true rib means the rib is directly attached to the sternum or breast plate. 8 9 10 attaches to the costal cartilage of 7, aka they are false ribs. 11 12 are floating ribs, they are false ribs. Based on indirect, direct or not at all connected to the sternum at all. Also where the major vessels that leave the heart is: between t4 and t5, they will get to the sternal angel, which is where the top of the heart is. Which makes it eas(cid:455) to (cid:271)(cid:396)eak (cid:894)(cid:449)he(cid:374) (cid:272)a(cid:396)tilage(cid:895).
