foot muscles Flashcards
what are the 4 muscle compartments
anterior compartment, lateral compartment and deep posterior compartment and superficial posterior compartment
what muscles are at the anterior compartment and give attachments
tibialis anterior
extensors digitorum longus
extensor hallucus longus
peroneus tertias
what muscles are at the lateral compartment and give attachments
peroneus brevis
peroneus longus
what muscles are at the superficial posterior compartment and give attachments
planters
gastrocnemius
soleus
what muscles are at the deep superficial compartment and give attachments
tibialis posterior
flexor hallucis longus
flexor digitorum longus
popliteus
what does the plantar aponeurosis cover
short intrinsic muscles
muscles supporting medial longitudinal arch
tibialis anterior and posterior
abductor hallucis and flexor digitorum brevis
flexor hallucinations longus
muscles supporting lateral longitudinal arch
peroneus longus brevis and tertius
abductor digit minimi
flexor digitorum longus 4th 5th toe
what muscles dorsiflex the foot and the limitations
20-30 knee extended, flex-35 degrees tibialis anterior extensors digitorum longus extensors hallucis longus peroneus tertias
limitations: tension in antagonist

limitations: tension in antagonist
anterior part of deltoid ligament
anterior talofibular ligament
what muscles produce inversion, limits
tibialis anterior and posterior 40-60 degrees
limits: dorsal talonavicular ligament
what muscles produce eversion, limits
peroneus longus,brevis,tertius 15-30 degrees
limits: impact of talus on the floor

what are the 4 layers in the foot
1- FDB Abductor digiti minimi, abdcutor hallucis
2- lumbricals, FHL, FDL
3- flexor digiti minmi adductor hallucis, flexor hallucis brevis
4- plantar and dorsal interossi
