(L4-L5)
the femoral nerve innervates the
quadriceps femoris:
>extension of stifle
necessary to support weight on hindlimb

the ventral branches of the sixth and seventh lumbar spinal >nerves and the first two sacral spinal nerves unite to form a >lumbosacral trunk. the nerves that arise from this trunk are the >caudal gluteal, cranial gluteal, and sciatic.

(L6-L7-S1-S2)
the sciatic nerve innervates the
biceps femoris, semimemb, semitend
>extensors of the hip
>flexors of the stifle
then splits into cranial and caudal branches

(L7-S1)
the tibial nerve is “the caudal portion of the sciatic nerve”
it separates from the common peroneal nerve in the thigh
>tarsal extensors
>digital flexors
gastrocnemius, popliteus, SDF, DDF
then splits into the plantar nerves

(L6-L7)

>tarsal flexors
>digital extensors
cranial tibial, fibularis longus, long digital extensor
