Question 10

attachment:

tuberosity of mavicular, all cuneiforms, cuboid, and bases of 2-4 MTs

Answer 10

tibialis posterior

Question 11

attachment:

posterior aspect of calcaneus via calcaneal tendon

Answer 11

plantaris muscle

Question 12

attachment:

posterior aspect of calcaneus via calcaneal tendon

Answer 12

soleus

Question 13

which muscle has the larger attachment on the calcaneous?

smaller attachment?

Answer 13

soleus has much larger insertion on calcaneus than the plantaris;

both attach to calcaneus via calcaneus tendon
