Answer:
Gastrocnemius
Explanation:
The twin, called the gastrocnemius muscle, in relation to the foot causes plantar flexion and leg flexion.
Said muscle is the main engine in the propulsion of the march, bearing large loads. That is why when it comes to practicing sports, it is very helpful to carry out preventive work for gastrocnemius using eccentric loads in addition to using stretching techniques.
This is located on the back of the leg, being the most superficial of the calf. It is located on the soleus muscle and extends from the femoral condyles to the calcaneal tendon.
Condyles are understood as rounded heads that fit in the hole to form the joints.
The twin is a biarticular muscle since its path crosses two joints, that of the knee and ankle.
Its function on the knee is to stabilize the femur, to avoid that there is an imbalance forward in the flexion movements. While, on the ankle acts as an extensor of the same with tendency to investment.
