yes you do if you want to be a primer ballerina but other wise you don't have to be flexible but it is good to be
flexion and lateral rotation of the neck
The main joint involved in flexion of the knee is the hinge joint formed by the femur and tibia. Additionally, the patellofemoral joint between the patella and femur also plays a role in knee flexion by aiding in the smooth movement of the patella during flexion.
popliteus is not involved in plantarflexion...its involved in leg flexion
The muscles involved in knee flexion are the hamstrings, gastrocnemius, and popliteus.
An example of pointing the toes would be extending the feet so that the toes are stretched out and the top of the foot is reaching away from the body. This is a common movement in activities such as ballet, yoga, and gymnastics.
The opposite movement of plantar flexion in the human body is dorsiflexion.
Extension is the opposite of flexion.
This movement is called flexion. It reduces the angle between the bones at a joint, typically involving the bending of the knee or elbow.
At the ankle joint: calf - platarflexion. Anterior tibialis is inovolved in countermovement dorsiflexion. At the knee joint: quadriceps - knee extension Hamstrings are involved in the knee flextion counter movement. At the hip: hamstrings, glutes, spinal errectors - hip flexion. Hip flexors, and abdominals are involved in the initial countrer movement and the "breaking" of the hip flexion. Additional upward thrust is also provided by the shoulders during arm thrust. Hip flexors, and abdominals are involved in the initial countrer movement and the "breaking" of the hip flexion. Big toe is mostly involved in the "toe off" movement. These are the main muscles involved in movement and coutnermovements.
extension
A movement used in dressage and ballet, is the Pirouette.
