week 6- foot and ankle Flashcards
where is the medial malleolus located
on the tibia, inferiorly and medially it is a lump (ankle)
where is the lateral malleolus located
laterally and inferiorly on the fibula. ankle bump
name the heel bone
calcaneus
what type of joint is the ankle
hinge joint
what typee of movement does the hinge ankle joint allow
dorsi flexion
plantar flexion
inversion
eversion
Where does the Achilles tendon insert
Calcaneus bone
What does the tibia articulate with in the ankle
Tailless
What bones for the ankle hing joiny
Tibia
Tailless
Describe eversion
Rotating foot down and in, lateral ankle moves up
Name the bone anterior to the talus
Navicular
Where is cuboid bone located
Laterally on the foot next to the cuneiforms
How many cuneiform bones are there
3
Name the cuneiform bones
Cuneiform 1 /2/3
What is located on the navicular bone
Tuberosity , laterally on the lateral side on the foot
What is on the cuboid bone
Tuberosity
What are attached to the metatarsals
Phalanges
How many arches are in the foot
3
What is the highest arch of the foot
Medial longtitudinal arch
Name the 3 arches of the foot
Medial longitudinal arch
Lateral longitudinal arch, laterally on middle of foot
Transverse arch (under metatarsals)
What is the importance of the foot arches
Slow the rate in which the force is transferred from the foot into the ground
- shock absorb
- allows energy to be returned to foot (efficiency of movement)
Name the joints in the foot
Tibiotalar joint
Subtalar joint
Describe the tibiotalar joint
Articulation of tibia and talus
Mortis joint
Flexion - dorsi and plantat
Describe the subtalar joint
Articulation of Talus and Calcaneus
Synovial plane joint
Inversion and eversion
What ligaments prevent over movement of ankle joints
Anterior talofibular ligament
Posterior talofibular ligament
Calcaneifibular ligament
Deltoid ligament
Where is the anterior talofibular ligament located
Anteriorly on the foot, connecting talus to fibular
Function of anterior talofibular ligament
resists anterior translation of foot on tibia
Resists inversion in plantar Flexion
Function of posterior talofibular ligament and location
posterior on talus to fibular
Prevents posterior translation of foot on tibia
Prevents rotatory subluxation of talus
Function and location of calcaneofibular ligament
Calcaneus to fibular (on side of foot medially)
Limit inversion in neutral or dorsi Flexion
Function and location of CFL
joins calcaneus to fibular medially
Limits inversion in neutral or dorsi Flexion
DL function and location
Made of ligaments on medial part of ankle medial maleolus, tibia, navicular
Limit eversion
Where is the tibialis anterior located
In front of tibia
Where is the extensor digitorum longis located
Straight down the front of the leg and into each toe
Where is the extensor halleckis longis located
Running deeper on anterior part of the leg to the big toe from shin
Where is the fibularis longus located
Laterally on the leg, from patella to shin height
