Gastrocnemius muscle

Blood vessels
The arterial supply is by the femoral artery and the obturator system. The lymphatic drainage closely follows the arterial supply.
The deep venous system of the thigh consists of the femoral vein, the proximal part of the popliteal vein, and various smaller vessels; these are the site of proximal deep venous thrombosis. The venae perfortantes connect the deep and the superficial system, which consists of the saphenous veins (the site of varicose veins).

Iliacus muscle
The Iliacus is a flat, triangular muscle, which fills the iliac fossa.
It arises from the upper two-thirds of this fossa, and from the inner lip of the iliac crest; behind, from the anterior sacroiliac and the iliolumbar ligaments, and base of the sacrum; in front, it reaches as far as the anterior superior iliac spine and anterior inferior iliac spine, and the notch between them.
The fibers converge to be inserted into the lateral side of the tendon of the Psoas major, which contributes to flexing the femur anteriorly onto the pelvis. Some of the iliacus fibers may reach the body of the femur, for about 2.5 cm. below and in front of the lesser trochanter.
The Iliacus is sometimes considered a part of the Iliopsoas group of hip flexor muscles.
This muscle is innervated by the anterior branches of the Femoral nerve (anterior branches of L2-3).
Working synergistically with the Psoas in gait (walking) and evaluation for low back pain, careful attention is placed on the slightly different spinal innervation from L4 with the psoas and a more horizontal action (leg further out).

Clinical significance
The gastrocnemius muscle is very prone to spasms; the painful, involuntary, contraction of the muscle for up to several minutes.
This muscle is prone to injury called torn calf muscle which is disabling.
The Gastrocnemius muscle may also become inflamed due to overuse. Anti-inflammatory and physical therapy may be necessary.

Anatomy
The gastrocnemius is located with the soleus in the posterior compartment of the leg. It originates from the posterior (back) surfaces of the distal head of the femur. Its other end forms a common tendon with the soleus muscle; this tendon is known as the calcaneal tendon or Achilles Tendon and inserts onto the posterior surface of the calcaneus, or mountain bone.
Deep to the gastrocnemius (farther from the skin) is the soleus muscle. Some anatomists consider both to be a single muscle, the triceps surae. The plantaris muscle and a portion of its tendon run between the two muscles, which is involved in "locking" the knee from the standing position. On the other side of the fascia are the tibialis posterior muscle, the flexor digitorum longus muscle, and the flexor hallucis longus muscle, along with the posterior tibial artery and posterior tibial vein and the tibial nerve. Since the anterior compartment of the leg is lateral to the tibia, the bulge of muscle medial to the tibia on the anterior side is actually the posterior compartment. The soleus is superficial midshaft of the tibia. Frequently there is a sesamoid bone called the "fabella" in the lateral head of gastrocnemius muscle.

General
In humans, the gastrocnemius (pronounced /ˌgæstrɒkˈniːmiəs/ or /ˌgæstrəˈniːmiəs/) muscle is a very powerful superficial muscle that is in the back part of the lower leg and also called the calf. It runs from its two heads just above the knee to the heel, and is involved in standing, walking, running and jumping. Along with the soleus muscle it forms the calf muscle.
