tibial.plantar medial: dial plantar.lateral plantar: lateral plantar. between 1 and 2 toes deep
fibular. dorsum of foot: superficial fibular.
,\Q\.what nerve can be compressed in tarsal tunnel - ANSWERS✔-tibular n
\Q\.Morton's neuroma - ANSWERS✔-compression of nerve passing through metatarsals
(possibly due to running) most likely between 3 and 4
\Q\.intrinsic muscles of dorsum of foot innervated by deep fibular n. - ANSWERS✔-extensor
digitorum brevis, extensor hallicus brevis
\Q\.dorsal pedis artery is palpated between - ANSWERS✔-extensor hallicus longus and extensor
digitorum logus (branches from anterior tibial a)
\Q\.talipes equinovares - ANSWERS✔-congenital club foot where the infants foot is rotated
medially and inverted
\Q\.borders of popliteal fossa and floor of - ANSWERS✔-UL: biceps femoris UM:
semimembranosus L: gatronemius
F: popliteus, joint, fibula and tibia
\Q\.contents of popliteal fossa (anterior to posterior) - ANSWERS✔-popliteal artery, popliteal v,
tibial n (also present common fibular n, sural n) place where nerve is susceptible because it is
superficial

longus: extension of digits, dorsiflex attaches @ distal phalanx 2-5
tibialis anterior: strongest dorsiflexor, inversion, arch support attaches @ medial cuneiforma
and 1st metatarsal
extensor hallicus longus: extension of big toe, dorsiflex attaches @ distal phalanx of 1
fibularis tertius: eversion, dorsiflex attaches @ base of 5th metatarsal
\Q\.muscles of anterior leg (innervation, BS) - ANSWERS✔-deep fibular n, anterior tibial a
\Q\.manifestation of common fibular n injury - ANSWERS✔-foot drop with steppage gait,
circumduction or waddle
\Q\.muscles of posterior compartment of leg innervation - ANSWERS✔-tibial n
\Q\.superficial muscles of posterior compartment of leg (function and proximal attachment) -
ANSWERS✔-attach @ achilies tendon
grastrocnemius: medial and lateral epicondyles, flex knee and plantarflex
soleus: tibia soleal line, plantarflex
plantaris: lateral supracondylar line of femur, flexes knee and plantarflex
\Q\.deep muscles of posterior leg (proximal, distal, function) - ANSWERS✔-popliteus: lateral
femoral condyle to tibia, laterally rotates femur on fixed tibia, flexes knee
flexor digitorum longus: tibia to base of phalanges 2-4, flexes toes
flexor hallicus longus: fibula to distal phalanx of big toe, flexes big toe
