Blood supply for compartments of leg5/16/2023 ![]() ***so it causes hip extension and knee flexion lumbosacral plexus innervate hip and lower limb (so strong quadricep leads to less knee injury) hamstrings where is it located posterior compartment of thigh,Īttach ischial tuberosity to priximal tibia/ can be felt medial and lateral to the knee stablize the kneebecause tendon runs anterior aspect and medial and lateral aspect of knee crosses anterior aspect of knee-exte$nd the knee (kick ball)ģ. one head of the 4 originates from ilium therefore crosses anterior to hip therefore it will flex the hip- just from this one headĬommon insertion via quadricps tendon, patella, patellar ligament to the tibial tuberosityĢ. posterior (hamstrings- cross back of hip and back of knee- extension of hip and flexion of knee) anterior comparment of high quadricep femoris quadricep femoris has 4 separate pts of origin, largely on anterior aspect of femurġ. anterior (inc quadricep, cross anterior aspect of knee- extensor of knee)ģ. Very powerful muscle, muscle fibers runs not perpenticular or parallel to the leg but is somewhere in between so it's able to do both actions of extension and lateral rotation iliotibial tract gluteus maximus inserts into IT band and extend to the lateral side of knee and helps to stablize the extended kneeĪction of gluteus maximus also exerts on the knee joint to help stablize it gluteus medius over top of the hip joint (abduction) gluteus maximus, medius, minimus with maximus on the most outer layer, then it's medius, then it's minimus medius and minimus both run over top of hip joint and both gonna abduct and stablize the pelvis gluteus medius and minimus stablizes the pelvis and contracts to keep pelvis in level 6 lateral rotators across the back of hip and originate in/on pelvis and extend to region of greater trochanter, horizontally across posterior aspect of hip joint and are all lateral rotator of hip flexor of hip illiopsoas= iliacus + psoas (dual origin, combined insertion)ĭeep to inguinal ligament! adductor of hip bundle of muscle on medial aspect of high and extend from pubis to humerus inferior to hip joint thigh in cross section skin, subq adipose, fascia lata (deep fascia just like the brachial fasica in the arm=deep ct sleeve enclosing thigh, ct septa extend to femur subdividing muscles of thigh into 3 compartments) what is a thickening of fascia lata lateral thickening of fascia lata forms IT tract 3 compartments of thigh 1. Medial rotation (some component of the other muscles), lateral rotation (muscle across back of joint and pull) gluteus maximus and actions large muscle in the bumb medial lateral rotation of femur muscular action of hip joint muscle vertically infront of hip joint will flex hip, muscle vertically at back of hip joint will extend hip, abduction (muscle on the side of hip joint), adduction (muscle pulling femur towards pubis), ![]() ![]() Bilateral contraction of quadratus lumborum stabalize the vertebral column unilateral contraction of QL lateral bending hip joint allows what movements 1/ ab/adģ.
