HLR, HF, HAbd, KF
Function of facia lata
Limits outward expansion of contracting thigh muscles and aids in venous return from lower limbs

HAdd, HF, HMR
What is the innervation of gracilis
Obturator nerve
What are the 3 muscles that attach to pes anserinus
How does a muscle strain occur
When muscles and tendons are forcibly stretched (lengthened) while being contracted
What are 4 symptoms of adductor muscle strain
What is the most commonly injured adductor muscle and why
Adductor longus because hip is placed in external rotation and abduction
Label the missing nerves
Label the 2 nerves of the anterior compartment of the leg
Label the missing nerve of the medial compartment of the thigh
Label the blood supply
Label the blood supply
Label blood supply and the 1 muscle
What are the 3 borders of the femoral triangle
Pectine is not a border
What are the 3 contents of the femoral triangle
Label the xray for blood supply
What is the blood supply of the medial compartment
How to determine origin of nerve injury in this photo (watch lecture on this part)
Top X = loss of all leg
Mid X = loss of thigh
Bottom X = loss of lower limb
Radiculopathy = at nerve root
Neuropathy = peripheral nerve
