The axis that can be used is the coronal axis which runs from side to side at a right angle to the sagittal plane of motion. Now we’ll begin …show more content…

I’ll begin by naming the agonist along with the antagonist as well as the action, insertion, and origin of the muscles.

Agonist: Gastrocnemius and soleus

Gastrocnemius:
Origin: lateral head-posterior surface of lateral condyle of femur and highest of three facets on lateral condyle, medial head, posterior surface of femur above medial condyle
Insertion: tendo calcaneus to middle of three facets on posterior aspect of calcaneus
Action: plantar flexes foot, flexes knee

Soleus:
Origin: soleal line and middle third of posterior border of tibia and upper quarter of posterior shaft of fibula including neck
Insertion: tendo calcaneus to middle of three facets on posterior surface of calcaneus
Action: plantar flexes foot (aids venous return)

Antagonist:

Tibialis anterior:
Origin: upper half of lateral shaft of tibia and interosseous membrane
Insertion: intermedial aspect of medial cuneiform and base of 1st metatarsal
Action: extends and inverts foot at ankle, holds up medial longitudinal arch of foot
