Musculature of the Leg: Anterior & Posterior (page 5)

These flashcards cover the key muscles of the anterior and posterior compartments of the leg, including their origins, insertions, and innervation.

Tibialis Anterior

Origin: lateral tibia, interosseous membrane; Insertion: medial cuneiform, metatarsal I; Nerve: deep fibular nerve.

Extensor Hallucis Longus

Origin: medial aspect of fibula, interosseous membrane; Insertion: distal phalanx I; Nerve: deep fibular nerve.

Extensor Digitorum Longus

Origin: lateral condyle of tibia, shaft of fibula, interosseous membrane; Insertion: middle and distal phalanges II - V; Nerve: deep fibular nerve.

Fibularis Tertius

Origin: distal shaft of fibula and interosseous membrane; Insertion: metatarsal V; Nerve: deep fibular nerve.

Gastrocnemius

Origin: lateral condyle and popliteal surface of femur; Insertion: calcaneus; Nerve: tibial nerve.

Tibialis Posterior

Origin: proximal half of tibia, fibula, interosseous membrane; Insertion: navicular, cuneiforms, metatarsals II - IV; Nerve: tibial nerve.

Flexor Hallucis Longus

Origin: shaft of fibula; Insertion: distal phalanx I; Nerve: tibial nerve.

Flexor Digitorum Longus

Origin: midshaft of tibia; Insertion: distal phalanges II - V; Nerve: tibial nerve.

Fibularis Longus

Origin: proximal calf of fibula, lateral condyle of tibia; Insertion: medial cuneiform, metatarsal I; Nerve: superficial fibular nerve.

Soleus

Origin: proximal third of tibia and fibula; Insertion: calcaneus; Nerve: tibial nerve.

Fibularis Brevis

Origin: shaft of fibula; Insertion: base of metatarsal V; Nerve: superficial fibular nerve.
