Lateral condyle and superior half of lateral surface of tibia and interosseous membrane: Medial and inferior surfaces of medial cuneiform and base of 1st metatarsal: Deep fibular (peroneal) nerve (L4, L5) Dorsiflexes ankle and inverts foot Extensor hallucis longus: Middle part of anterior surface of fibula and interosseous membrane
The fascia lata is a fibrous sheath that encircles the thigh like a subcutaneous stocking and tightly binds its muscles. On the lateral surface, it combines with the tendons of the gluteus maximus and tensor fasciae latae to form the iliotibial tract, which extends from the iliac crest to the lateral condyle of the tibia.

Inferior end of lateral supracondylar line of femur; oblique popliteal ligament: Weakly assists gastrocnemius in plantarflexing ankle Soleus: Posterior aspect of head and superior quarter of posterior surface of fibula; soleal line and middle third of medial border of tibia; and tendinous arch extending between the bony attachments
By location or innervation (ventral and dorsal divisions of the plexus layer); By development on the basis of their points of insertion (a posterior group in two layers and an anterior group); and; By function (i.e. extensors, flexors, adductors, and abductors). [15] Some hip muscles also act either on the knee joint or on vertebral joints.
The iliotibial tract or iliotibial band (ITB; also known as Maissiat's band or the IT band) is a longitudinal fibrous reinforcement of the fascia lata.The action of the muscles associated with the ITB (tensor fasciae latae and some fibers of gluteus maximus) flex, extend, abduct, and laterally and medially rotate the hip.
Lateral (from Latin lateralis 'to the side') describes something to the sides of an animal, as in "left lateral" and "right lateral". Medial (from Latin medius 'middle') describes structures close to the midline, [2] or closer to the midline than another structure. For example, in a human, the arms are lateral to the torso.
[12] These are known as the medial and lateral malleolus. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia.
Another function of bones is the storage of certain minerals. Calcium and phosphorus are among the main minerals being stored. The importance of this storage "device" helps to regulate mineral balance in the bloodstream. When the fluctuation of minerals is high, these minerals are stored in the bone; when it is low they will be withdrawn from ...
