Unit II Lec 21 Flashcards
Ankle allows what movements
flexion and extension of foot at medial malleolus of tibia and lateral malleolus of fibula
All articular surfaces of foot are covered with ________ cartilage
HYALINE
A fibrous capsule surrounds the foot and attaches to the ______
tibia, both malleoli, talus
A ________ lines the fibrous capsule
synovial membrane
inversion and eversion of foot occur between what two bones
talus and calcaneus
On the medial side of foot and ankle a very strong ligament attached proximally to the medial malleolus
deltoid ligament
another name for deltoid ligament
medial collateral ligament
component of the deltoid ligament down to the sustentaculum tali of the calcaneus
tibiocalcaneal component
component of the deltoid ligament down to the tuberosity of the navicular bone.
tibionavicular component
component of the deltoid ligament down to the anterior medial surface of the talus
anterior tibiotalar component (also called deep fibers)
On the later side of foot and ankle, main ligament with three parts
lateral collateral ligament
Part of lateral collateral ligament from the lateral malleolus to the area anterior to the lateral articular facet and lateral part of the neck of the talus
anterior talofibular ligament
Part of lateral collateral ligament runs posteriorly from the lateral malleolar fossa to the lateral tubercle (posterior process) of the talus
posterior talofibular ligament
Part of lateral collateral ligament runs from the lateral malleolus to the lateral surface of the calcaneus
calcaneofibular ligament
most frequently sprained ligament in ankle injuries
anterior talofibular ligament
tendons of the peroneus longus and brevis cross this ligament
calcaneofibular ligament
thickenings around the ankle to keep the long tendons in position as they cross joints
retinacula
Two anterior retinacula of the ankle
superior and inferior extensor retinacula
One posterior retinacula of the ankle
flexor retinaculum
Two lateral retinacula of the ankle
superior and inferior peroneal retinacula
the tibialis anterior tendon, anterior tibial artery, deep peroneal nerve, extensor hallucis longus tendon, extensor digitorum longus tendon, and the peroneus tertius muscle, extensor hallucis brevis and extensor digitorum pass beneath the
superior and inferior extensor retinaculum
tibialis posterior tendon, flexor digitorum longus tendon, posterior tibial artery, tibial nerve, and flexor hallucis longus tendon pass beneath
flexor retinaculum
Passing beneath the superior and inferior peroneal rectinaculum on the lateral side of the ankle are the _______
peroneus longus and brevis
Mnemonic for foot bones
Tiger Cubs Need Milk In Little Cups
Tarsal bones of foor
Talus, Calcaneus, Navicular, Medial Cuneiform, Intermediate Cuneiform, Lateral Cuneiform, Cuboid
Metatarsals and phalanges of foot are arranged same as
hand
Three arches of the foot
medial longitudinal, the lateral longitudinal, and the transverse
arch is formed by all the tarsal bones, except for the
medial longitudinal arch
Plantar ligaments that support the medial longitudinal arch
plantar calcaneonavicular (spring), the long plantar, and the short plantar ligaments
medial longitudinal arch is supported by what mx of the foot
intrinsic muscles of the sole, plantar aponeurosis
