Gastrocnemius - Correct Answer A: plantar flexes and inverts foot at ankle, O:
femoral condyles
I: Calcaneus via Achilles tendon
Soleus - Correct Answer A: plantar flexes and inverts foot at ankle
O: Upper 1/3 of tibia
I: Calcaneus via Achilles tendon
Tibias Anterior - Correct Answer A: Dorsiflexed and inverts foot at ankle
O: Lateral condyle of tibia
I: plantar surface of first metatarsal and cuneiform
Tibias Posterior - Correct Answer A: Inverts and plantar flexes the foot at ankle.
Medial ankle stabilizer.
O: Lateral part of posterior surface of tibia, proximal 2/3 of medial surface of fibula.
I: Tuberosity of acicular, with branches to sustenaculum tail of calcaneus, plantar
surfaces of all 3 cuneiforms, cuboid, and bases of 2nd, 3rd, and 4th metatarsal
bones.
Popliteal - Correct Answer A: Rotates tibia medially on the femur, or femur laterally
on tibia. Brings knee out of full extension. Helps with posterior stability of knee
O: Lateral condyle of the femur
I: Posterior surface of tibia above solely line.
Plantar is - Correct Answer a: plantar flexes and inverts the foot at the ankle, flexes
the leg at the knee.
O: Lower part of lateral supracondylar line of femur, and oblique popliteal ligament of
knee.
I: Posterior part of the calcaneus medial to the Achilles tendon.
Peroneus Longus - Correct Answer A: Eversion and plantar flexion of foot at ankle.
Gives lateral stability to the ankle.
O: Head and proximal 2/3 of lateral tibia
I: Lateral margin of plantar surface of 1st cuneiform and metatarsal.
Peroneus Bevis - Correct Answer A: Eversion and plantar flexion of the foot at the
ankle. Gives lateral stability to the ankle.
O: Distal 2/3 of the lateral fibula.
I: Tuberosity on lateral side of 5th metatarsal
, Peroneus Tetris - Correct Answer A: Dorsiflexed and averts the foot at the ankle.
O: Distal 1/3 of anterior surface of fibula.
I: Dorsal surface of 5th metatarsal.
Extensor Halluces Longus - Correct Answer A: Extends distal phalanx of big toe.
Continued action extends proximal phalanx and dorsiflexed and inverts the foot at
the ankle.
O: Middle 1/2 of the anterior surface of fibula,
I: Dorsal surface of base of distal phalanx of hallux (big toe)
Extensor Digit rum Longus - Correct Answer A: Extends the lateral 4 toes.
Dorsiflexed and averts foot at the ankle.
O: Lateral condyle of tibia, head and proximal 3/4 of the anterior surface of fibula.
I: Divides into 4 tendons after passing under extensor retinaculum to insert on dorsal
surfaces of bases of middle and distal phalanges of the 2nd-5th toes.
Flexor Halluces Longus - Correct Answer Action:
Flexion of great toe
Plantar flexion of foot
Inversion of foot
Origin:
Fibula (posterior shaft)
Intraosseous membrane
Insertion:
Distal phalanx of great toe
Comment:
Powerful muscle for "push-off" of foot during walking and running
Flexor Digit rum Longus - Correct Answer Action:
Flexion of toes 2-5
Plantar flexion of foot
Inversion of foot
Origin:
Tibia (posterior middle shaft)
Insertion:
Distal phalanges of toes 2-5
Comment:
Tendon provides attachment for quadrates Plantae (insertion) and numerical (origin)
muscles
Vast us Medial is - Correct Answer A: Extends leg at knee and draws patella
medially. O: Lower 1/2 of intertrochanteric line, tendons of adductor Magnus and
adductor longus
I: Medial border of the patella and through the ligament patellae into tibia tuberosity
