-Bifid/prong at the spinous process -Holes in the transverse process -Squared almost semi-circle body -Triangular foramen -Lateral view looks like a chicken wing

Question 33

Distinguishable features of Thoracic vertebrae

Answer 33

-Slightly Isosceles, downwards pointing spinous processes -Circular foramen -additional articular facets for ribs -laterally looks like switch blade

Answer 35

ATLAS = C1 AXIS = C2

Question 36

how do atlas and axis vertebrae differ from the other C vertebrae structurally

Answer 36

Atlas is a ring bone with no body or spinous processes Axis has a body and peglike processes called dens

Question 37

how do atlas and axis vertebrae differ from the other C vertebrae structurally

Answer 37

Atlas is a ring bone with no body or spinous processes Axis has a body and peglike processes called dens -dense allows pivot of head
