. What would you like to do?
What type of action do the piriformis, superior/inferior gemellus, obturator internus/externus and quadratus femois?
Lateral rotators (posterior)
what type of action do the illiacus, Psoas major, rectus femoris, and sartorius conduct?
What type of action do the gluteal maximus, biceps femoris, semi-mebranosus, and semi-tendinosus conduct?
What muscles make up the adductors?
- Adductor magnus, brevis, and longus
What muscles make up the abductors?
- gluteal minimus
- gluteal medius
- tensor fascia lata
What is the orgin, insertion, and action of the piriformis?
- Origin = anterior surface of sacrum and sacrotubrous ligament
- Insertion = superior border of greater trochanter
- Action = lateral rotation, abduction
What is the orgin of the superior gemellus?
What is the orgin of the inferior gemellus?
What is the insertion of the superior and inferior gemellus?
What is the orgin and insertion of quadratus femoris?
- Origin = ischial tuberosity
- Insertion = quadrate tubercle
What is the strongest lateral rotator muscle?
What three extensor muscles arise from the ischial tuberocity?
- Biceps femoris

What is the insertion of the the semimembranosus?
medial condyle of tibia
What is the insertion of the semitendinosus?
medial surface of superior tibia
What is the insertion of the biceps femoris?
lateral head of fibula
What is the innervation of all the hamstring muscles?
tibial division of sciatic nerve
What actions do all the hamstring muscles produce?
- extend thigh
- flexion of leg
What hamstring muscles medially rotate the femur?
what hamsting muscle laterally rotates the leg?
What is the orgin and insertion of the gluteus maximus?
- origin = back of ilium
- insertion = iliotibial tract and gluteal tuberosisty (femur)
what is the innervation of the gluteus maximus?
inferior gluteal nerve
What muscle hip muscle is one of two main anti gravity muscles?
What action do the gluteus minimus and medius conduct?
Abduction and medially rotates thigh
What causes a positive trendelenburg sign?
injury of gluteus medius and minimus
What is the trendelenburg sign?
dropping of pelvis on leg being raised while walking
where is the lesion found in a patient with trendelenburg sign?
the contralateral side of droped pelvis
What two muscles attach to the illio-tibial tract?
- gluteus maximus
- tensor fascia lata
What is the orgin of the psoas major?
transverse processes of T12-L5
What is the innervation of the illiacus and psoas major?
- Iliacus = Femoral nerve
- Psoas = ventral rami L1, L2, L3
What nerve innervates all anterior muscles of the hip joint?
Femoral nerve which is made up of the ventral rami of L1-L3
What muscle is the major flexor of the femur?
What is the origin of the Rectus Femoris?
Anterior inferior iliac spine
What is the longest muscle in the body?
What is the origin of the sartorius?
Anterior superior iliac spine
What is the largest muscle of the hip adductors?
What is the origin of the adductor and hamstring part of the adductor magnus?
- adductor part = inferior ramus of pubis and ischium
- Hamstring part = ischial tuberosity
What is the insertion of the adductor and hamstring part of the adductor magnus?
- adductor part = gluteal tuberosity, linea aspera, medial supracondylar line
- Hamstring part = adductor tubercle of femur
What is the innervation of the adductor and hamstring parts of the adductor magnus?
- adductor = obturator nerve
- hamstring = tibial part of sciatic nerve
What is the action of the hamstring and adductor parts of the adductor magnus?
- hamstring = extension of thigh
- adductor = adduction of thigh
What is the origin and insertion of the adductor longus?
- origin = body of pubis
- insertion = linea aspera
What is the innervation of the adductor longus?
What nerve innervates all the hip adductor muscles?
What is the insertion of the adductor brevis?
pectineal line and linea aspera
What is the origin and insertion of the Pectineus?
- origin is superor ramus of pubis
- Insertion = pectineal line
What the only adductor muscle that is innervated by a nerve other than the obturator nerver?
Pectineus is also innervated by the femoral nerve
What is the weakest adductor muscle that also crosses the knee joint?
What nerve innervates all anterior muscles?
What nerve innervates the posterior muscles of the hip joint and what is the excetption?
- Tibial nerve
- exception = short head biceps (femoral nerve)
What nerve innervates all the medial muscles of the hip joint and what is the exception?
- Obturator nerve
- Exception = pectineus (femoral nerve) Hamstring adductor magnus (sciatic nerve)
What are the boundaries of the femoral triangle?
