The Foot Flashcards
label the bones of the foot
- body of talus
- calcaneus
- navicular
- cuboid
- medial, intermediate and lateral cuneiform
- metatarsals 1-5
What is the function of the plantar fascia?
what movements can occur at the mortise/ankle joint?
flexion and extension
what other movements of the ankle can occur at the subtalar (below the talus) joints?
eversion and inversion
label the joints
- The talonavicular joint (1), is a ball and socket joint which allows the foot to pivot from side to side.
- The talocalcaneal joint (2), helps this process allowing for some lateral sliding movement
The integrity of the arch of the foot is maintained by which passive factors?
- shape of united bones
- plantar spring ligament or plantar calcaneonavicular ligament
- long plantar ligament
- short plantar ligament
The integrity of the arch of the foot is maintained by which dynamic factors?
- intrinsic muscles of the foot
- long flexor tendons
- tendon of tibialis posterior and fibularis longus
label the layer 1 muscles of the foot
label layer 2 of the foot including the muscles and neurovascular structures
what are the two terminal branches of the tibial nerve which innervates the intrinsic muscles of the foot?
present in layer 2 of the foot
medial plantar and lateral plantar nerves
Which are the two terminal branches of the posterior tibial artery which supply the foot region?
present in layer 2 of the foot
medial plantar artery
lateral plantar artery
what is the function of layer 3 foot muscles?
- adductors and short flexors of the toes
what is the function of the interossei muscles in layer 4 of the foot?
Layer 4 contains the interossei – these are subdivided into plantar interossei which adduct the digits and dorsal interossei which abduct the digits.
