Kyphosis

Answer 3

excessive kyphosis in T spine (excessive posterior curve)

D/T comp. fx, postural habits, pathology

Question 4

Lordosis

Answer 4

Reversal of Cervical Curve

Answer 6

reduction of normal lordosis of C spine

d/t postural habits, MVA, or other trauma

Question 7

Spina Bifida

Answer 7

lamina fail to fuse resulting in defect in the arch

Question 8

Transverse Processes

Answer 8

2 of them
project laterally from junction of ledicles and lamina
