more leg Flashcards
posterior superficial compartment of leg has which 3 muscles and what innervates it
gastronemius, soleus, and plantaris
tibialis n innervates it
tricep surae
the three muscles of the posterior compartment that all insert into achilles tendon
gastronemius, soleus, plataris
“three headed calf”
retrocalcaneal bursa
between calcaneous and achilles tendon
what innervates both the deep and superficial posterior compartment of leg
tibial nerve
muscles of the posterior deep compartment
poplitius (screw home mechanism that allows us to flex knee)
tibialis posterior
flexor digitorum longus
flexor hallicis longus
tibialis posterior not only does plantar flexion, it also does…
inversion!
if tibial nerve is injured what will be very difficult?
plantar flexion, ankle flexion, and inversion
explain Tom Dick and Harry muscles
three deep posterior muscles go around the medial malleolus. Tibialis posterior (most medial) flexor Digitorum longus (in the middle) and flexor Hallicus longus (most lateral)
Tom Dick And Now Harry =
tibialis posterior, flexor digitorum longus, posterior tibial Artery, tibial Nerve, and flexor hallicis longus
tarsal tunnel syndrome
the flexor retinaculum covers the muscles of the posterior deep compartment. It goes from the medial malleolus to the calcaneal tuberosity.
*if someone is really flat footed, it can leave to excessive compression on this area. It can lead to these tendons or artery being effected. They can show weakness, or numbness and tingling on plantar foot.
ankle dorsi flexion is
lifting your toes to your nose, also called extension
injury to deep peroneal fibular nerve can lead to this diagnosis
drop foot! they can not actively dorsi flex
If fibular head fractures, what nerve can be effected?
common peroneal / fibular N
what compartment are your leg dorsiflexors
anterior compartment
what compartment are your leg plantar flexors
poster compartment
what compartment are your leg everters?
lateral compartment
what muscles are your inverters of the leg?
tibialis posterior & anterior and extensor hallicis longus
sustenaculum tali
a bump on the medial side of calcaneus
it promotes elevation and maintenance of
chassis effect
intertwining flexor digitorum longus and flexor hallicis longus
which two muscles create a stir up for transverse arch?
tibialis posterior and peroneus longus
pes planus
essentially a flat foot. its caused by failure of the transverse arch, which involves the tibialis posterior and peroneus longus
also tarsal tunnel syndrome makes you have a flat foot
popliteal fossa is
the space behind the knee
the borders of popliteal fossa:
it makes a diamond shape - first two are superior to 3/4
- superolateral- bicep femoris
- superomedial - semitendinosus and semimembinosus
- med head -medial gastrocnemius
- lat head - lateral gastrocnemius
What is inside of the popliteal fossa?
popliteal fossa is back of knee so:
popliteal artery and veins
and your genicular arteries
the femoral artery turns into the
popliteal artery
the popliteal artery splits into the
anterior tibial artery at the popliteal fossa and posterior tibial artery
once the anterior tibial artery gets to the tibia and fibula it splits and…
the anterior tibial artery stays anterior, and then there’s a posterior tibial artery that breaks off
the anterior tibial artery eventually becomes
the dorsalis pedis artery once it hits the ankle joint
