Question 3

Plantaris distal

Answer 3

Posterior surface of calcaneus via calcaneal tendon

Question 4

Answer 4

Tibial nerve S1, S2

Question 5

Soleus Innervation

Answer 5

Tibial nerve S1, S2

Question 6

Plantaris innervation

Answer 6

Tibial nerve S1, S2

Question 7

Gastrocnemius action

Answer 7

Plantarflexes ankle when knee is extended; raises heel during walking; and flexes knee joint

Question 8

Soleus Proximal

Answer 8

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

Question 9

Soleus action

Answer 9

Plantarflexes ankle; steadies leg on foot

Question 10

Plantaris proximal

Answer 10

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

Question 11

Plantaris action

Answer 11

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

Question 12

Popliteus Proximal

Answer 12

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

Question 13

Popliteus Distal

Answer 13

Posterior surface of tibia, superior to soleal line

Question 14

Popliteus Innervation

Answer 14

Tibial nerve L4, L5, S1

Question 15

Popliteus action

Answer 15

Weakly flexes knee and unlocks it by laterally rotation femur on fixed tibia, may also medially rotate tibia of unplanted limb

Question 16

Flexor hallucis longus proximal

Answer 16

Inferior 2/3s of posterior surface of fibula and inferior part of interosseous membrane

Question 17

Flexor hallucis longus distal

Answer 17

Base of distal phalanx of great toe (Hallux)

Question 18

Flexor hallucis longus innervation

Answer 18

Tibial nerve S2, S3

Question 19

Flexor hallucis longus action

Answer 19

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

Question 20

Flexor Digitorum longus proximal

Answer 20

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

Question 21

Flexor Digitorum longus distal

Answer 21

Bases of distal phalannges of lateral four digits

Question 22

Flexor Digitorum longus innervation

Answer 22

Tibial nerve S2, S3

Question 23

Flexor Digitorum longus action

Answer 23

Flexes lateral four digits; plantar flexes ankle; supports longitudinal arches of foot

Question 24

Tibialis posterior proximal

Answer 24

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

Question 25

Tibialis posterior distal

Answer 25

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

Question 26

Tibialis posterior innervation

Answer 26

Tibial nerve L4, L5

Question 27

Tibialis posterior action

Answer 27

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