Answer:
Striated muscle
Step-by-step explanation:
The striated muscle fibre is multinucleated and the nuclei are peripherally arranged. it is innervated by the voluntary nervous system hence concerned with voluntary movement. the sarcoplasm of the muscle fibre has the contractile proteins myosin and actin. The gastrocnemius muscle also called leg tricep originates at the back of the femur and patella joining the soleus and is attached to the Achilles tendon at the heel. Action of the gastrocnemius pulls the heel up and thus extends the foot downward propelling force in running and jumping.
