Lateral foot

'Small toe'

4

5

MC herniation in lumbar and cervical vertebra?

Lumbar - between L4-L5 or L5-S1
Cervical - between C5-C6 or C6-C7

6

Triceps reflex

C7 - digits 2,3,4

7

C6 - lateral forearm

8

Biceps brachi reflex

C5 - lateral arm

9

Herniated IV disc

Posterolateral

10

Why is disc herniation more common in posterolateral position?

Posterior annulus fibrosus is weaker than anterior

PLL is narrower and weaker than anterior

11

Curvature of primary curvature

Concave anteriorly

Thoracic, sacral

think: firST - sacral and thoracic curve first
