HAL Lab 9: Anterior leg and knee Flashcards
What is the deep fascia of the leg
Crural fascia
The anterior compartment of the leg are mainly ankle extensors- what is this movement and what is the nerve for this
This is to bring the toes to towards the shin. This is also known as dorsiflexion. Nerve is deep peroneal nerve
What are the superficial muscles of the anterior leg comp (med to lat)
Tibialis anterior, Extensor digitorum longus, Extensor hallucis longus, Peroneas/fibularis tertius
What is the main action of the lateral compartment of the foot- and its innervation: fibularis/peroneus. Which tendon is more superficial.
Eversion of the foot: superficial peroneal nerve Superficial is peroneus longus
What is the cutaneous supply to the dorsum of the foot
The superficial peroneal nerve (the deep peroneal nerve does the webspace between first and second toe)
What nerve supplies cutaneous to the medial leg and foot. What vein does this run with
Saphenous nerve runs with Great saphenous vein (which passes anterior to medial malleolus)
What is the ant. Tibial artery called when it crosses the ankle joint
The dorsalis pedis which goes through the first webspace to join the plantar arteries
What is the order of the tendons that insert into the Pes Anserinus (Anterior to posterior)
Most anteriorly is sartorius, Gracilis and then posteriorly semitendinosus.
What structure do you expect to find running around the neck of the fibula. what artery (+vein) is this close to
Common peroneal nerve before it splits into deep and superficial branches. This is close to ant. Tibial artery (and vein) which is going through the hole in the interosseous membrane
How are cruciate ligaments named in relation to the tibia
They are named based on their origin. (cross middle finger over index to see path)
What are menisci made of and how does the lateral and medial one compare, what does this mean for mobility
Made of fibrocartilage. The medial one is more C shaped when viewed from birdeyeview whereas lateral one is more circular and meets up in a ring. So lateral one is more mobile - also has extracapsular collateral ligament (vs capsular medial CL) so less likely to be injured.
Where does popliteas tendon go and its job
It goes into the tendon attaching to the lateral condyle of the femur.
It rotates the femur laterall and therefore unlocks the knee from standing
Fat pads behind the patella are intracapsular but…
extra-articular: outside the synovium
