Thorax & Rib Cage Flashcards
What is the location of the transverse processes in relation to the corresponding spinous process for each of the Thoracic vertebrae?
RULE OF 3s
T1-T3 = SP and TPs are at the same level
T4-T6 = SP is located half a segment below the corresponding TPs
(T5 SP is located halfway between the TPs of T5 and T6)
T7-T9 = SP is located a full step below the corresponding TPs
(T8 SP is located at the level of the T9 TPs)
T10 = SP is located a full step below the corresponding TPs (same as T7-T9)
T11 = SP is located half a segment below the corresponding TPs (same as T4-T6)
T12 = SP and TPs are at the same level
