Extensor hallucis longus- Extends hallux, DF
Deep peroneal nerve
Ligament that prevents anterior hip dislocation
Iliofemoral

Sartorius-femoral nerve (sec) Gluteus minimus- superior gluteal never (prim) Gluteus medius- " (prim) Tensor fasciae latae- " (prim) Piriformis- L5, S1, S2 (sec)
Internal hip rotators
Tensor fasciae latae, gluteus medius, gluteus minimus, adductor longus, adductor brevis, pectineus, adductor magnus
External rotators hip
Primary Gluteus maximus Obturator internus Quad. Femoris Gemellus sup. And Inf.
Secondary: Gluteus medius Gluteus minimus Obturator externus Piriformis Biceps femoris
The sustentaculum talk of the calcaneus is attached to the navicular bone by way of a ligament. This ligament supports the head of the talus at the talonavicular articulation and assists in resisting flattening of the medial longitudinal arch.
Spring ligament
The interosseous membrane of the leg is an example of
