Hip & Thigh --> Bones and Muscles Flashcards
what si the location of the lesser trochanter of the femur?
posteromedial
where is the intertrochanteric crest of the femur located?
posteriorly
the linea aspera is located on the —1— surface of the femur and distally divides into the —-2—-
1 posterior
2 suprachondylar lines
what do the suprachondylar lines delineate?
the site of insertion of the popliteal muscle
what are the flexors of the hip and where do they arise from?
Psoas Major
Iliacus
from the posterior abdominal wall
what are the 3 main compartments of the thigh?
Anterior (extensors) occupies ~60%
Medial (adductors)
Posterior (flexors)
what is the fascia lata and what is its function?
investor of the thigh
limits bulging of muscles and works as a venous pump
what is the iliotibial tract?
lateral thickening of the fascia late, common aponeurotic tendon of insertion of Gluteus Maximus and Tensor of the Fascia Lata
what is the main function of Gluteus Maximus?
inserts into the lateral condyle of the tibia causes lateral rotation and extension of the hip
MAJOR FUNCTION is to extend the hip from sitting down
what is the main function of the tensor of the facia lata?
lateral side of the proximal part of the thigh
flexes and abducts and medially rotates the hip
what are the site of insertion of Gluteus Medius and Minimus? and what is their function?
Greater Trochanter
Abduction and Medial Rotation AND maintenance of the hip at coronal plane during swing phase
what muscle that comes from the pelvic region hast 2 gamely with them?
Obturator Internus
what are the main muscles that cause lateral rotation of the hip?
piriformis
obturator internus and gemeli
Quadratus femoris
Obturator Externus
what are all the muscles of the gluteal region?
GM Gm and gm piriformis obturator internus and gemeli Quadratus femoris
what are the muscles above Sartorius? (L-M)
Iliopsoas
Pectineus
Adductor Longus
Gracilis
what are the main muscles of the anterior compartment of the hip?
Iliopsoas
Pectineus
Quadriceps Femoris
what is the main function of iliopsoas?
Flexes the truck over the hip/Lifts leg
MAINTAINS LUMBAR LORDOSIS
what is the action of pectineus?
Flexion and Adduction
dual action = dual nerve and blood supply
what is the main function of the quadriceps femoris and what are its components?
Extensor of the Knee against gravity Rectus Femoris Vastus Lateralis Vastus Medialis (reaches more distally) Vastus Intermedius
what are the main components of the Medial and lateral Patellar Retinaculum
the insertion sit of the medial and lateral vastus around the patella
what is particularly important about rectus femoris?
crosses both he hip and the knee joint and as such is able to flex the hip and extend the knee
what are the muscles contained in the medial (adductor) compartment of the knee?
Pectineus Adductor Longus Adductor Brevis Adductor Magnus Gracilis
the adductor muscles originate at —1— and insert into —2—
1 Inferior Pubic Rami
2 Linea Aspera
the adductor hiatus is formed by which muscle and is located where?
by adductor magnus and is located between the tendon fibres and the medial condyle of the femur. Through it passes the Femoral Artery
