plantar
intrinsic muscle of dorsum of foot?
extensor digitorum brevis
extensor digitorum brevis joins?
lateral side of EDL tendons
extensor hood made up of these tendons?

deep fibular nerve supplies?
extensor digitorum brevis, then heads towards first web space sensory
dorsalis pedis artery continuation of?
anterior tibial
dorsalis pedis gives off?
arcuate artery heads laterally, metatarsal and digital, then gives off deep plantar to complete the deep plantar arch

which crosses what? FHL vs. FDL sole of foot?
FDL over FHL
which lumbricals uni vs. bi?
1st: unicipital
all others: bicipital
purpose of flexor accessorius?
optimize pull of FDL in all ankle positions
Layer 3 short muscles of sole of foot?

how many PAD? vs. DAB?
3 PAD
4 DAB
posterior tibial artery does what in sole of foot?
splits into medial.
lateral makes plantar arch, competed the arch by attaching to termination of dorsalis pedis from dorsum of foot
Tibial nerve does what in sole of foot?
splits into medial plantar ( medial 3 1/2 toes) lateral plantar (lateral 1 1/2 toes)
medial of lateral plantar nerve of tibial nerve supplies all the intrinsic muscles of foot?
lateral plantar nerves
