|
|
gastrocnemius muscle is polyarticular. true or false. name its ORIGIN and INSERTION
|
true. O condyles of the femur
I Calcaneus |
action: flex the knee (tibofemoral joint) and plantar flex the ankle (talocrural joint)
|
|
|
soleus is deep to the gastrocnemius. true or false. name its ORIGIN and INSERTION
|
true. O soleal line, posterior surface of the tibia and proximal posterior surface of the fibula I Calcaneus via calcaneal tendon
|
action: plantar flex the ankle (talocrural joint)
|
|
|
plantaris (short muscle belly, longest tendon in the body) - also mildly polyarticular
(plantaris is like the palmaris longus of the foremarm) absent in 10% of population |
O lateral condyle of the femur
I Calcaneus via calcaneal tendon |
action: weak plantar flexion of the ankle (talocrural joint) weak flexion of the knee (tibofemoral joint)
|
|
|
popliteus - the key that unlocks the knee
|
O lateral epicondyle of the femur
I proximal posterior aspect of the tibia |
|
|
|
peroneus longus (everts the foot)
|
O proximal two-thirds of lateral fibula
Ibase of the first metatarsal |
fibula head to the first (toe) metatarsal
-longus crosses lateral to medial |
|
|
peroneus brevis (everts food and assists to plantar flex the ankle - talocrural joint)
|
O distal two-thirds of the lateral fibula
I Tuberosity of the ffifth metatarsal |
|
|
|
what is the name of the rare third peroneus muscle
also: extensors are on the front or the back of the lower leg |
peroneous tertius - will be found anterior to the front of the ankle - acutally a short branch of the extensor digitorum longus that attaches along with the brevis at the 5th metatarsal
also: FRONT |
|
|
|
tibialis anterior is large, superficial and easiest to identify. lie directly lateral to the tibial shaft
|
I tibial tuberosity
O base of 1st metatarsal (like the peroneus longus) |
|
|
|
extensor digitorum longus
|
fibula head and tibia (two heads) and goes down the lateral side, extending out to the 2-5 toes
|
longus crosses lateral to medial
|
|
|
extensor hallucis longus
|
fibula 1/2 way down - to big toe Metatarsal 1 like the peroneus longus
|
longus crosses lateral to medial
|
