Question 1

Gastrocnemius - O

Answer 1

• Lateral head: lateral aspect of lateral femoral condyle

* Medial head: popliteal surface of femur, superior to medial condyle

Question 2

gastrocnemius - I

Answer 2

• Posterior surface of calcaneus via Calcaneal tendon

Question 3

gastrocnemius - A

Answer 3

• Plantarflexes ankle, raises heal when walking, flexes leg at knee

Question 4

Soleus -O

Answer 4

Posterior aspect of head of fibula, superior quarter of posterior surface of fibula, soleal line, and medial border of tibia

Question 5

Soleus - I

Answer 5

Posterior surface of calcaneus via calcaneal tendon

Question 6

Soleus - A

Answer 6

Plantarflexes ankle; steadies leg on foot

Question 7

Plantaris -O

Answer 7

Inferior end of lateral supracondylar line of femur and oblique popliteal ligament

Question 8

Plantaris - I

Answer 8

Posterior surface of calcaneus via calcaneal tendon

Question 9

plantaris - A

Answer 9

Weakly assists gastrocnemius in plantarflexing ankle; function is probably mainly proprioceptive

Question 10

soleus, plantaris, gastrocnemius innervation of superficial m. of post. comp. of leg

Answer 10

Tibial nerve (S1, S2)

Question 11

Popliteus -O

Answer 11

Lateral surface of lateral condyle of femur and lateral meniscus (intra-articular; within cavity of knee joint)

Question 12

Popliteus - I

Answer 12

Posterior surface of tibia, su- perior to soleal line

Question 13

Popliteus - A

Answer 13

Weakly flexes knee and unlocks it by laterally rotating femur on fixed tibia, may also medially ro- tate tibia of unplanted limb

Question 14

Popliteus - Innervation

Answer 14

Tibial nerve (L4, L5, S1)

Question 15

Flexor Hallucis Longus - O

Answer 15

nferior two thirds of posterior sur- face of fibula and inferior part of interosseous membrane

Question 16

Flexor Hallucis Longus - I

Answer 16

Base of distal phalanx of great toe (hallux)

Question 17

Flexor Hallucis Longus - A

Answer 17

Flexes great toe at all joints; weakly plantarflexes ankle; supports medial longitudinal arch of foot

Question 18

Flexor Hallucis Longus - Innervation

Answer 18

Tibial nerve (S2, S3)

Question 19

Flexor digitorum longus - O

Answer 19

Medial part of posterior surface of tibia inferior to soleal line and by a broad tendon to fibula

Question 20

Flexor digitorum longus - I

Answer 20

Bases of distal phalanges of lateral four digits

Question 21

Flexor digitorum longus - A

Answer 21

Flexes lateral four digits; plantarflexes ankle; supports longitudinal arches of foot

Question 22

Flexor digitorum longus - Innervation

Answer 22

Tibial nerve (S2, S3)

Question 23

Tibialis Posterior -O

Answer 23

Interosseous membrane, posterior surface of tibia inferior to soleal line, and posterior surface of fibula

Question 24

Tibialis Posterior -A

Answer 24

Plantarflexes ankle; inverts foot; supports medial longitudinal arch of foot

Question 25

Tibialis Posterior -I

Answer 25

Primarily to tuberosity of navicular; also to cuneiforms, cuboid, and bases of 2nd–4th metatarsals

Question 26

Tibialis Posterior -Innervation

Answer 26

Tibial nerve (L4, L5)
