Anterior and Lateral Leg Flashcards
Tibialis Anterior M. : Origin
Lateral tibial condyle and superolateral 1/2 of tibia
Tibialis Anterior M. : Insertion
Medial surface of first (medial) cuneiform and first metatarsal base
Tibialis Anterior M. : Functions
Dorsiflexion and inversion
Extensor Digitorum Longus M. : Origin
- Lateral tibial condyle
- Anterior fibular surface
- Interosseous membrane
Extensor Digitorum Longus M. : Insertion
- Each of the four tendons forms an extensor expansion over dorsum of lateral four proximal phalanges that divide into
- Two lateral slips (distal phalanx)
- One central slip (middle phalanx)
Extensor Digitorum Longus M. : Functions
- Extends lateral four digits
- Dorsiflexion
Fibularis Tertius M. : Origin

Extensor Hallucis Longus M. : Origin
Anteromedial fibular surface and interosseous membrane. Medial to distal half of the proximal attachment of extensor digitorum longus
Extensor Hallucis Longus M. : Insertion
Base of distal phalanx of hallux
Extensor Hallucis Longus M. : Functions

Fibularis Longus M. : Origin
Head and superolateral 2/3 of fibula
passes inferior just posterior to lateral malleolus
Fibularis Longus M. : Insertion
Runs obliquely and distally across sole of foot to attach distally to first metatarsal and medial cuneiform bone
Fibularis Longus M. : Functions
