Joints Flashcards
What is the ankle joint stabilised by?
medial deltoid ligaments and the lateral ligaments
What is the subtalar joint?
A synovial modified saddle joint
talus and calcaneus
weak capsule
capsule supported medially, laterally and posteriorly by talocalcanean ligaments
stabilised by interosseous talocalcanean ligament
inversion
eversion
The ankle joint
synovial hinge joint
covered in hyaline cartilage
enclosed by a joint capsule and lined with a synovial membrane
between the distal end of the tibia and fibula and then talus of the foot
dorsiflexion and plantarflexion
inferior tibio-fibular joint
medial aspect of the fibula and fibular notch on lateral aspect of the tibia
anterior inferior, posterior inferior and transverse tibio fibular ligaments
rotation of the fibula on the tibia during ankle dorsiflexion
Functions of the ankle joint
gives a stable base of support provides a rigid lever to push off absorbs shock of the body weight conforms the foot to irregular terrain provides propulsion and restraint in walking
Talocalcaneonavicular joint
synovial ball and socket joint
Calcaneo cuboid joint
synovial saddle joint
simple capsule lined with synovial membrane
Intertarsal joints
produce gliding movements
tarsometatarsal and intermetatarsal joint
produce gliding movements
metatarsalphalangeal joint
flexion, extension
abduction and adduction
Interphalangeal joint
flexion and extension
What is the plantar aponeurosis?
thickening of deep fascia in the sole of the foot
supports the longitudinal arch of the foot and protects deep structures in the sole
