elements of sternum
Manubrium
Body
Xiphoid process
top middle notch on the top of the manubirum
Jugular notch
the notch on the sides of the jugular notch on the manubrium
Clavicular notch
what is inferior to the clavicular notch
1st costal notch
what does the does the sternal angle articulate
With the 2nd rib costal cartilage
why transverse ridges on the sternum
Fusion of the segmental parts of the sternum

2-7
what does the zipohoid process articulate with
7
ribs that attach direction to sternum via there own costal cartialge
true ribs (1-7)
when ribs costal cartilage articulate with costal cartilage of the rib above
False ribs (8-12)
what ribs do not at all attach to the sternum
Floating (11-12)
are floating ribs false ribs
Yes
parts of the posterior rib
Head
Neck
Tubercle
what does the head of the rib articulate with
Superior: above vertebra
Inferior: own vertebra
separates head from tubercle
Neck
regions of the tubercle of the rib
Articular and non articular
what does the articular part of the tubercle do
medial, oval for transverse fossa of own vertebra
What does the non articular part of the rib do
attachments of ligaments and is roughened
different of superior and inferior margin of ribs
Inferior is sharp
superior is smooth
what is found on the inferior margin of the rib
Intercostal groove
where does the rib articulate posteriorly
Head of the rib and the superior and inferior costal facets of the rody of the vertebra
Tubercle of the rib and the costal fascet of the transverse process of the vertebra
(3 places total for ribs 2-9)
