Muscles of the leg and Foot
"The main framework of the body (skeleton) is covered by muscles, whose function is to permit movement and maintain posture. Sensory receptors in the muscles monitor the tension and length of the muscles and provide the nervous system with information about the position of the body parts, thereby enabling posture to be maintained."

Part one upper leg
Muscles involved with the movement of the hips and thigh:
-The Gluteal group of muscles consist of the Gluteus Minimus, Medius, Maximus. These muscles including the Fascialate extend, flex and rotate the hip
-In the Lateral Rotator group the Superior Gemellus, Inferior Gemellus, Obturator Internus, Quadratus Femerus and Piriformis rotate the hip laterally.
-The Adductors such as the Pectineus, Gracilis Muscle, Adductors Magnus, Longus, Brevis and Minimus move the hips back and perform Flexion and Extenion.
Iliotibiol Tract: collagen fibers that extend from thigh to knee.
Muscles that move the leg:
-The muscles the extend the leg at the knee are the Quadriceps, Femoris Iliopsoas and Sartius.
-The hamstrings Located at the back of the leg flex the leg at the knee.
Part two the Popliteus Muscle
The Popliteus muscle allows you to unlock the knee for extension and flexion. is located behind the knee.
Part Three lower leg
Muscles that flex or extend the foot and ankles:
Soleus: standing and walking.
Gastrocnemius: flexes and extends the ankle, foot and knee.
Plantaris: not everyone has this muscle its use is superseded by the Gastrocnemius.
Abductor Hallucis: moves the big toe.
Tibialis Anterior: moves foot upward and inward.
Extensor digitorum: points toes down.
Fibularis Longus: Moves foot sideways and downward.
Fibularis Brevis: Helps move foot downward.
Achillies Tendon: stores the elastic energy for monument in physical activity.
Key terms
Abduction: is the movement of part of the body away from the center.
Adduction: is the movement back toward the center of you body.
Flexion: a bendin motion at a joint that decreases the angle between the two bones on either side of the joint.
Extension: the straightening of a bent joint increasing the distencebetween the bones one either side of the joint.
