Pes Planus
Where is the middle axis in the foot
axis goes through second toe
Thick-ass layer of fascia which provides support to the skin on the bottom of the foot
plantar aponeuorsis
Thickened fascial bands attached to side of phalanges; form tunnel for passage of long tendons to toes and prevents bowstringing
Fibrous digital sheaths
Fibrous digital sheaths – found on dorsal or plantar side of toes?
plantar
Muscles of layer 1 of sole of the foot
1) flexor digitorum brevis
2) abductor hallucis
3) abductor digiti minimi
Layer 1 muscles of the sole of the foot all take origin from…
calcaneus
Action of layer 1 muscles of the sole
Flexion of toes; abductors abduct
Tendons of this muscle end on the middle phalanges and split to allow passage of flexor digitorum longus to distal phalanges
Flexor digitorum brevis
What is found in layer 2 of the sole of the foot
1) Lumbricals
2) Quadratus Plantae
3) Flexor Digitorum Longus (TENDON)
4) Flexor Hallucis Longus (TENDON)
Actions of lumbricals
1) flex metatarsophalangeal joints
2) extend interphalangeal joints
These muscles attach to the tendons of flexor digitorum longus and extend to proximal phalanges of toes and extensor expansions
lumbricals

weakness of intrinsic muscles of the foot
What should you lift, bro, to strengthen the intrinsic muscles of the foot
towel toe curls. 5x5 with a drop set
Action of quadratus plantae
pulls on tendons of flexor digitorum longus laterally to redirect flexor pull toward calcaneus. Flexion of toes.

Tendon passes between two sesamoid bones under the head of the first metatarsal
Muscles of layer 3 of the sole of the foot
1) flexor hallucis brevis
2) adductor hallucis
3) flexor digiti minimi brevis
Has two tendons that insert to proximal phalanx of big toe; sesamoid bones present in each tendon
Flexor hallucis brevis
Small muscle to proximal phalanx of little toe in layer 3
flexor digiti minimi
Two heads of adductor hallucis
oblique and transverse
Composition of layer four of the foot
1) interosseus muscles
2) tendon of peroneus longus
3) tendon of tibialis posterior
Action of dorsal interossei
abduction
Action of plantar interossei
