,Gastrocnemius - Correct Answers: A: plantarflexes and inverts foot at ankle, O:femoral condyles
I: Calcaneus via achilles tendon
Soleus - Correct Answers: A: plantarflexes and inverts foot at ankle
O: Upper 1/3 of fibia
I: Calcaneus via achilles tendon
Tibialis Anterior - Correct Answers: A: Dorsiflexes and inverts foot at ankle
O: Lateral condyle of tibia
I: plantar surface of first metatarsal and cuneiform
Tibialis Posterior - Correct Answers: A: Inverts and plantarflexes 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 navicular, with branches to sustenaculum tali of calcaneus, plantar surfaces of all 3
cuneiforms, cuboid, and bases of 2nd, 3rd, and 4th metatarsal bones.
Popliteus - Correct Answers: 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 soleal line.
Plantaris - Correct Answers: 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 Answers: 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 Brevis - Correct Answers: 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 Tertius - Correct Answers: A: Dorsiflexes and everts the foot at the ankle.
O: Distal 1/3 of anterior surface of fibula.
I: Dorsal surface of 5th metatarsal.
Extensor Hallucis Longus - Correct Answers: A: Extends distal phalanx of big toe. Continued action
extends proximal phalanx and dorsiflexes 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 Digitorum Longus - Correct Answers: A: Extends the lateral 4 toes. Dorsiflexes and everts 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 Hallucis Longus - Correct Answers: Action:
Flexion of great toe
Plantar flexion of foot
Inversion of foot
Origin:
Fibula (posterior shaft)
Interosseous membrane
Insertion:
Distal phalanx of great toe
