even more leg! Flashcards
the posterior compartment of leg gets blood from which artery?
the posterior tibial artery
the lateral compartment of the leg gets blood from which artery?
the peroneal artery
this is a branch of the posterior tibial artery that splits off to supply the lateral compartment
the peroneal artery does what after the medial malleolus?
after the medial malleolus it splits off under the foot to be a medial and lateral plantar artery
what is the talocrural joint? What articulates

what motions does the talocrural joint allow?
plantars flexion and dorsi flexion
what is the subtalor joint?
the articulation between the talus, calcaneous, and other little bones. Its under the talocrural
what motions does the subtalor joint allow?
inversion and eversion
the deltoid ligament is also called the
MCL (medial collateral ligament)
the deltoid ligament is a huge ____ ligament
weightbearing
the deltoid ligament is found on the
medial ankle ligaments
what makes up the deltoid ligament (aka the medial collateral ligament)
anterior tibiotalar ligament posterior tibiotalar ligament tibiocalcaneal ligament tibionavicular ligament (they all come off the tibia)
what side of the ankle do we sprain more often?
the lateral side but that’s do to over inversion
what ligaments are found on the lateral side of ankle?
anterior tibiofibular ligament (most common inversion sprain)
calcaneofibular ligament
posterior tibiofibular ligament
*retinaculum on this side to help bind peroneal tendons down
anterior drawer test
if you pull the ankle forward, and you feel excessive motion, sprained ligaments of ankle. You compare to your other side of body
anterior compartment of foot we have two types of retinaculum. Explain
we have an superior extensor retinaculum
and we have an inferior extensor retinaculum (also called crural cruciate ligament)
7 tarsal bones
cuboid, talus, navicular, calcaneus, medial, intermediate, and lateral cunieforms
Come To Cuba Next Christmas
underneath the head of the talus is the
spring ligament - prevents your head of talus from driving down into the ground
what kind of joints are your intertarsal joints?
gliding - for flexibility as we walk on different surfaces
tarsometatarsal joints are between what and what and what kind of joint are they?
gliding joints
they are between your tarsal bones and the base of your meta tarsals (between small bones and 1st set of long bones before the three / 2 of thumb)
Metatarsal phalangeal joints - what kind of joint are they and where are they?
they are condyloid bones - allow for plantar flexion, dorsi flexion, abduction and adduction
they are between the distal end of the metatarsal and the proximal phalangeal
interphangeal joint type of joint? and where?
hinge joint - mainly dors and plantar flexion
between the proximal, medial, and distal phalangeal (separates proximal and distal big toe phalangeal)
Sinus tarsi syndrome & the sinus tarsus
the “eye of the foot”. It is this space between the calcaneus and talus of foot. When you injure your foot this area can really have localized pain and inflammation
