Table 4. Number of Muscular Variations in Common Between the Legs Studied
Table 5. Occurrence of Individual Variations in Nerves
two fureal nerves
S9 with three branches
prefixed
sciatic nerve with six roots
obturator nerve from S2 and S3 only
femoral nerve mainly from S2-S4
anterior division innervates extensor iliotibialis lateralis
dorsal division fused with anterior division
dorsal division fused with middle division
two branches to iliacus
middle division anastomoses with anterior division
anterodorsal division does not go through femoral notch
branch of anterior division perforates iliacus
cutaneous branch perforates extensor iliotibialis lateralis
branch of middle division perforates vastus medialis
branch to vasti innervates extensor iliotibialis lateralis
anterior branch of anterior division cutaneous
twig to pars caudifemoralis independent
branch to flexor cruris lateralis does not perforate caudofemoralis
paraperoneal nerve enters peroneal sheath
cutaneous peroneal branch perforates gastrocnemius pars externa
cutaneous peroneal branch absent
distal cutaneous tibial branch absent
twig to tail present
nonmuscular peroneal twig deep to vastus lateralis pars postica
branch to flexor cruris medialis from posterior tibial division
extra twigs join cutaneous tibial branches
branch to flexor cruris medialis an independent division
branch to flexor cruris medialis perforates flexor ischiofemoralis
two twigs to flexor ischiofemoralis
independent extra branch innervates extensor iliofibularis
branch to femorocruralis innervates gastrocnemius pars media
superficial and deep peroneal nerves do not join
independent extra branch innervates flexor perforatus digiti IV
anastomosis involving posterior division
branch to gastrocnemius pars externa an independent division
branch to gastrocnemius pars media innervates femorocruralis
extra branch innervates flexor perforatus digiti III
branch to gastrocnemius pars interna perforates plantaris
branch to gastrocnemius pars interna innervates plantaris
