Question Lower Limb Spinal Dermatomes

Yes they do ask about and to have a general outline will help a lot in the exam

Here's a quick tip

Just remember L2-L3 for anterior hip
and shift (with overlap) the numbers single segment for the next joint, so anterior knee will be L3-L4 and anterior ankle will be L4-L5

For the posterior innervation it's same as anterior but with downward shift (without overlap)
So posterior hip is L4-L5, posterior knee L5-S1, posterior ankle S1-S2

I didn't say there's no overlap
Posterior Knee L5 S1
Posterior Ankle S1 S2

What I meant by the shift, is the shift in relation to the relevant anterior segments
Anterior Knee L3 L4
Posterior Knee L5 S1

To add on that, remember First Aid's mnemonic!

L4 down on all FOURS (knee).
L1 is IL (inverted = inguinal ligament)
