Periodontal Ehlers-Danlos syndrome Periodontal EDS (pEDS) causes dental problems, particularly inflamed or absent gums and poor tooth development, on top of typical features of cEDS. It is rare but can be inherited from one parent only, as only one faulty gene is needed to develop the condition.
Ribs 1, 2, 11 and 12 can be describes as âatypicalâ â they have features that are not common to all the ribs. Rib 1 is shorter and wider than the other ribs. It only has one facet on its head for articulation with its corresponding vertebrae (there isnât a thoracic vertebrae above it).
men and women both have 24 ribs - 12 on each side. The first seven pairs of ribs are connected to the sternum (breast bone). Rarely, some pople have one more or less pairs of ribs due to various genetic mutations. just wanted to add a little on the source of the misconception. In the Biblical story of Adam and Eve, God made Eve from one of Adam's ribs, and this is why the myth that men have one fewer rib than women begun.
