What is the head of the rib consist of
Consist of two articular facets separated by crest of the head.
27
Fill in the blanks
28
Which ribs are atypical
1,2,10,11,12
29
Why is rib 1 atypical
is shorter and wider than the other ribs. It only has one facet on its head for articulation with its corresponding vertebra. The superior surface is marked by two grooves, which make way for the subclavian vessels.
30
Why is rib 2 atypical
is thinner and longer than rib 1, and has two articular facets on the head as normal. It has a roughened area on its upper surface, from which the serratus anterior muscle originates.
31
Why is rib 10 atypical
only has one facet – for articulation with its numerically corresponding vertebra.
32
Why is rib 11 atypical
have no neck, and only contain one facet, which is for articulation with their corresponding vertebra.
33
Why is rib 12 atypical
have no neck, and only contain one facet, which is for articulation with their corresponding vertebra.
34
Rib 1 is thinner than rib 2
False | Rib 2 is thinner and longer
35
Fill in the blanks with typical, atypical, floating
36
Name different sections of sternum
37
the manubrium, body and xiphoid process. In children, these elements are joined by ———. Which ossifies to bone during adulthood.

Where is Clavicular notch?
45
Where is clavicular notch
46
Either side of the jugular notch, there is a large ———. These articulate with the medial ends of the clavicles
Either side of the jugular notch, there is a large fossa. These fossae articulate with the medial ends of the clavicles
47
On the lateral edges of the manubrium, there is a ——— for articulation with the costal cartilage of the ——st rib, and a ——— for articulation with part of the costal cartilage of the 2nd rib.
On the lateral edges of the manubrium, there is a facet, for articulation with the costal cartilage of the 1st rib, and a demi facet (half-facet) for articulation with part of the costal cartilage of the 2nd rib.
48
Why is sternal angle used as an aid to count ribs?
. The sternal angle is commonly used as an aid to count ribs, as it marks the level of the 2nd costal cartilage.
49
Inferiorly, the manubrium articulates with the body of the sternum, forming the —————.
Sternal angle
50
The ——— is the most inferior and smallest part of the sternum. Located at the level of the T—— vertebrae. In some individuals, ——— articulates with part of the costal cartilage of the ———th rib.
