KIN 421 Exam 2
Ankle mortise bones - ANS-Talus, tibia and fibula
Midfoot bones - ANS-Navicular, 3 cuneiforms and cuboid
Primary insertion for tibialis posterior - ANS-Navicular tuberosity
Forefoot/toes bones - ANS-5 MTs and 14 phalanges
3 joints in forefoot - ANS-MTP, DIP and PIP
3 joints in the ankle - ANS-Tibiofibular, talocrural and subtalar
Transverse tarsal joint - ANS-Between talus, navicular, calcaneus and cuboid.
"Spring" ligament - ANS-Plantar calcaneonavicular ligament, provides support for
medial longitudinal arch
What two joints represent junction between rear-foot and mid-foot? -
ANS-Talocalcaneonavicular and calcaneocuboid
Junction between mid-foot and forefoot? - ANS-Tarsometatarsal joints or "lisfrancs"
Intrinsic foot muscles - ANS-Those originating on one of the bones of the foot and
directly influence motion of foot/toes
Extrinsic foot muscles - ANS-Originate on the lower leg or distal aspect of femur.
4 layers of intrinsic foot muscles - ANS-Superficial, middle toes, deep and interosseous.
Superficial layer of intrinsic foot muscles - ANS-Abductor hallucis, abductor digiti minimi
and flexor digitorum brevis
Middle toe layer of intrinsic foot muscles - ANS-Quadratus plantae, lumbricals, flexor
hallucis longus and flexor digitorum longus
Deep layer of intrinsic foot muscles - ANS-Flexor digiti minimi brevis
