Gastrocnemius
The Gastrocnemius (calf muscle) is the primary mover. The Synergist (or assistor) muscle is the Soleus.
The gastrocnemius muscle is the synergist of plantar flexion of the foot. It works together with the soleus muscle to help push the foot downward and point the toes.
The gastrocnemius is a synergist of the soleus.
The answer would be false. The soleus muscle is superficial to the tibia NOT the gastrocnemius.
type of contraction of gastrocnemius muscle?
Yes, it is a secondary muscle (synergist/stabilizer) used in the squat. There is a link below in which you can get a chart of the muscles used in a squat: go down about halfway and you'll see the chart.
A synergist muscle helps a prime mover muscle in creating a specific movement. It assists the prime mover by reducing unnecessary movements and helping stabilize the joint. Synergist muscles work together to produce coordinated movement.
A synergist muscle is a muscle that aids another by promoting the same movement.
The muscle that aids the jaw in closing is the temporalis muscle. The masseter is the muscle that primarily moves the jaw.
gastrocnemius
No, the gastrocnemius muscle forms the belly of the calf in the lower leg.
The synergist to the smiling muscle (zygomaticus major) is the orbicularis oculi muscle, which is responsible for the contraction around the eyes and contributes to the overall expression of a smile.
