Leg Flashcards
What does the superior extensor retinaculum attach to
Anterior borders of tibia and fibula
What divides the posterior compartment of the leg into superficial and deep parts
Transverse inter muscular septum
What does the inferior extensor retinaculum attach to
Stem - calcaneus
Limbs - medial malleolus and medial border of foot
Where is the flexor retinaculum attached to
Medial malleolus to medial surface of calcaneus
What is the superior fibular retinaculum attached to
Lateral malleolus to lateral surface of calcaneus
What is the inferior fibular retinaculum attached to
Fibular tubercle of calcaneus and lateral surface of calcaneus
What arteries are the terminal branch of the popliteal artery
Posterior tibial artery and anterior tibial artery
When you feel your pulse posterior to medial malleolus, what artery is that
Posterior tibial artery
What are the terminal branches of the posterior tibial artery
Medial and lateral plantar arteries
What branch of the posterior tibial artery gives off originates from the proximal part, descends within the flexor hallucis longus, and gives off branches to ankle and heel
Fibular artery
What branch of the posterior tibial artery gives off arterial anastomoses around the knee and passes laterally around the neck of fibula
Circumflex fibular artery
What branch of the posterior tibial artery supplies the medial aspect of the heel
Medial calcaneal branches
What branch of the posterior tibial artery supplies anastomoses around the ankle joint
Posterior medial malleolar branch
What nerve and vein does the anterior tibial artery travel with
Deep fibular nerve
Anterior tibial veins
At the ankle, what does the anterior tibial artery name change into
Dorsalis pedis artery
How does a fracture at the tuberosity of the 5th metatarsal happen
Foot is suddenly inverted, fibularis brevis rips it off
Where does the blood supply for the lateral side of the leg come from
Fibular artery (from posterior leg ) And anterior tibial artery (from anterior leg)
origin of gastrocnemius
LATERAL HEAD: lateral surface of lateral condyle of femur and distal end of lateral supracondylar line of femur
MEDIAL HEAD: popliteal surface of femur
insertion of gastrocnemius
common tendon (achille’s tendon)
action of gastrocnemius
plantar flexion of foot at ankle flexion of leg at knee joint
innervation of gastrocnemius
tibial nerve
origin of soleus
soleal line, medial border of tibia, head of fibula, tendinous arch b/w tibial and fibula
insertion of soleus
calcaneal tendon
action of soleus
plantar flexion of foot at ankle
innervation of soleus
tibial nerve
origin of the plantarius
lateral supracondylar line of femur
insertion of the plantarius
b/w gastrocnemius and soleus, along medial border of achille’s tendon, inserts into calcaneus
