The crural fascia (deep fascia of the leg) forms a complete investment to the muscles, and is fused with the periosteum over the subcutaneous surfaces of the bones. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group Deep fascia (or "investing fascia" is a layer of Fascia which can surround individual muscles and divide groups of muscles into compartments
It is continuous above with the fascia lata, and is attached around the knee to the patella, the ligamentum patellæ, the tuberosity and condyles of the tibia, and the head of the tibula. The fascia lata is the Deep fascia of the Thigh. Thickness It is an investment for the whole of the thigh but varies in thickness in different parts The patella or kneecap is a thick triangular Bone which articulates with the Femur and covers and protects the knee joint The patellar ligament ( anterior ligament) is the central portion of the common tendon of the Quadriceps femoris, which is continued from the Patella to The tibia, shinbone, or shankbone is the larger and stronger of the two Bones in the Leg below the Knee in vertebrates and connects
Behind, it forms the popliteal fascia, covering in the popliteal fossa; here it is strengthened by transverse fibers, and perforated by the small saphenous vein. The popliteal fossa is a space or shallow depression located at the back of the Knee-joint.
It receives an expansion from the tendon of the Biceps femoris laterally, and from the tendons of the Sartorius, Gracilis, Semitendinosus, and Semimembranosus medially; in front, it blends with the periosteum covering the subcutaneous surface of the tibia, and with that covering the head and malleolus of the fibula; below, it is continuous with the transverse crural and laciniate ligaments. The biceps femoris is a muscle of the posterior (the back Thigh. The Gracilis ( Latin slender is the most superficial muscle on the Medial side of the Thigh. The semitendinosus is a Muscle in the back of the Thigh; it is one of the Hamstrings Structure The semitendinosus remarkable for the great The semimembranosus is a Muscle in the back of the Thigh. It is the most medial of the three Hamstring muscles
It is thick and dense in the upper and anterior part of the leg, and gives attachment, by its deep surface, to the Tibialis anterior and Extensor digitorum longus; but thinner behind, where it covers the Gastrocnemius and Soleus. In human anatomy the tibialis anterior is a Muscle in the shin that spans the length of the Tibia. The Extensor digitorum longus is a Pennate muscle situated at the lateral part of the front of the leg In humans the gastrocnemius (pronounced /ˌgæstrɑkˈnimiəs/ muscle is a very powerful superficial Muscle that is in the back part of the lower leg In humans and some other mammals the soleus is a powerful Muscle in the back part of the lower Leg (the calf
It gives off from its deep surface, on the lateral side of the leg, two strong intermuscular septa, the anterior and posterior peroneal septa, which enclose the Peronæi longus and brevis, and separate them from the muscles of the anterior and posterior crural regions, and several more slender processes which enclose the individual muscles in each region.
A broad transverse intermuscular septum, called the deep transverse fascia of the leg, intervenes between the superficial and deep posterior crural muscles.
