Homework Answers
1. Action of the muscle - Soleus is a sole shaped ,multipennate muscle which lies deep to gastrocnemius.
a. Flexion produced by soleus. It is very important in walking and running.6.
b. Plantar flexion of the foot at ankle joint.
2. Origin - a. Fibula - back of head , upper 1/4 posterior surface of shaft.
b. Tibia - soleal line and middle 1/3 of the shaft.
c. Tendinous soleal arches - between tibia and fibula.
3. Insertion - the tendon of soleus muscle combined with the tendon of gastrocnemius to give Achilles’ tendon which is inserted in to posterior surface of calcaneum.
4. Axis of rotation - extension of ankle , dorsal surface of foot is moved away from shin ( pointing toes).
5. Antagonist muscle - Tibialis anterior muscle which causes dorsiflexion is antagonistic muscle .
7. Synergistic muscle - Gastrocnemius is a synergistic muscle .
