muscles of the leg Flashcards
what is a compartment
package of muscles wrapped together by connective tissue
what are the 4 compartments of the leg
- anterior
- lateral
- superficial
- deep
name the highlighted muscle, origin, insertion, and movement
- tibialis anterior
- insertion: base of first metatarsal and medial cuneiform
- origin: lateral proximal tibia, tibial condyle
- movement: dorsiflexion, inversion
name the highlighted muscle, origin, insertion and movement
- extensor digitorum longus
- origin: head of fibula, lateral tibia condyle
- insertion: lateral 4 toes
- movement: dorsifelxion, eversion, extension of IP joints
name the highlighted muscle, origin, insertion, and movement
- extensor hallicus longus
- origin: interosseous membrane
- insertion: base of distal phalanx of toe 1
- movement: dorsiflexion, extension of IP joints
name the highlighted muscle, origin, insertion, and movement
- tibialis posterior
- origin: interosseous membrane
- insertion: navicular tuberosity, base of 2-4 metatarsal, medial cuneiform
- movement: plantar flexion, inversion
name the muscle, origin, insertion, and movement
- flexor hallicus longus
- origin: interosseous membrane
- insertion: base of distale phalanx of toe 1
- movement: plantarflexion, inversion, plantarflexion of the MTP and IP joints
name the muscle, origin, insertion, and movement
- flexor digitorum longus
- origin: posterior surface of tibia
- insertion: base of distal phalange of toes 2-5
- movement: plantarflexion, inversion, plantarflexion of MTP and IP joints
which 3 muscles form the achilies tendon?
- gastrocnemius
- soleus
- plantaris
name the muscle, origin, insertion, movement
- gastrocnemius
- origin: medial and lateral femoral condyles
- insertion: calcaneus (through achilies tendon)
- movement: plantarflexion, knee flexion
does the gastrocnemius cross a joint? if so, what joint?
yes, crosses knee joint
name the muscle, origin, insertion, movement
- soleus
- origin: posterior surface of tibia and fibula
- insertion: calcaneus (via achillies tendon)
- movement: plantarflexion
name the muscle, origin, insertion, and movement
- plantaris
- origin: lateral femoral condyle
- insertion: calcaneus (via achillies tendon)
- movement: plantarflexion, knee flexion
does the plantaris cross a joint? if so what joint?
yes, knee joint
name the muscle, origin, insertion, movement
- fibularis longus
- origin: lateral fibula head
