PAS 407 Foot UPDATED ACTUAL Questions and CORRECT Answers
Most superior tarsal bones
no musculotendinosus attachments, numerous articula-
tions
body articulates with tibia superiorly, fibula laterally, calca-
neous inferiorly
Talus head projects anteriorly, inferomedially to articulate with
navicular bone
- palpable on medial side, especially during eversion
largest/strongest bone of foot
supports talus superiorly, transmits weight of entire body
into ground
superior surface of anterior 2/3 articulates with talus
- sustentaculum tali - medial projection that supports talus
calcaneus
superiorly, serves as pully for flexor hallucis longus tendon
inferiorly
anterior surface articulates with cuboid bone
prominent calcaneal tuberosity posteriorly
- contains medial, lateral and anterior tubercles
, boat shaped bone
articulates with head of talus proximally, cuneiforms dis-
tally
prominent medial tuberosity for muscle attachment
navicular - palpable on medial side, in eversion/inversion
lateral most bone of talus
prominent tubercle for muscle attachment, groove to ac-
commodate fibularis longus tendon
cuboid
cuneiforms
, 3 medial wedge shape bones
articulate with navicular proximally, cuboid laterally,
metatarsals 1-3 distally
wedge shape contributes to transverse arch of foot
- shape provides some depth to plantar surface to absorb
ground reaction forces and prevent plantar structures to
be crushed during weight bearing
2 phalanges in great toe
3 phalanges in digits 2-5
no saddle joint with 1st MTP joint
- saddle joint = flexion/extension, abduction/adduction
and circumduction
metatarsals/phalanges prominent tuberosity at base of 5th metatarsal
- attachment of peroneus (fibularis) brevis muscle
ankle joint
