Question 6

What is the origin, insertion, innervation, and action of the pectineus?

Answer 6

Origin: superior ramus of pubis
insertion: pectineal line of femur
innervation: femoral nerve
action:adducts and slightly flexes hip

Question 7

What is the origin, insertion, innervation, and action of the Iliacus?

Answer 7

Origin: Ilaic crest, iliac fossa
insertion: =tendon of psoas major
innervation: femoral
action: conjointly with other iliopsoas to flex and laterally rotate the hip joint. Stabilize hip joint when standing

Question 8

What is the origin, insertion, innervation, and action of the Psoas Major ?

Answer 8

Origin:sides of T12- L5 vert
insertion: lesser trochanter
innervation: anterior rami of lumbar nerves
action: conjointly with other iliopsoas to flex and laterally rotate the hip joint. Stabilize hip joint when standing

Question 9

What is the origin, insertion, innervation, and action of the psoas Minor?

Answer 9

Origin:sides of T12-L1 vert
insertion: pectineal line and iliopubic eminence
innervation: anterior rami of lumbar nerves
action:conjointly with other iliopsoas to flex and laterally rotate the hip joint. Stabilize hip joint when standing

Question 10

What is the origin, insertion, innervation, and action of the Sartorius?

Answer 10

Origin: Anterior superior iliac spine and superior part of nothc
insertion: Superior part of medial surface of tibia
innervation: Femoral nerve
action: flexes, abducts, and laterally rotates hip joint. Flexes knee

Question 11

What makes up the iliopsoas?

Answer 11

psoas major and iliacus.

Question 12

What muscles make up the quadriceps femoris?

Answer 12

Rectus femoris, vastus lateralis, vastus medialis, vastus intermedius

Question 13

What is the origin, insertion, innervation, and action of the rectus femoris?

Answer 13

Origin: AIIS and ilium
Insertion:common tendinous and independent attatchments to base of the patella
innervation: femoral nerve
action: extends knee, rectus femoris also steadies hip joint and helps iliopsoas flex hip joint

Question 14

What is the origin, insertion, innervation, and action of the Vastus Lateralis?

Answer 14

Origin: Greater trochanter and lateral lip of linea aspera
Insertion:common tendinous and independent attatchments to base of the patella
innervation: femoral nerve
action: extends knee, rectus femoris also steadies hip joint and helps iliopsoas flex hip joint

Question 15

What is the origin, insertion, innervation, and action of the Vastus Intermedius?

Answer 15

Origin: anterior and lateral surfaces of shaft of femur
Insertion:common tendinous and independent attatchments to base of the patella
innervation: femoral nerve
action: extends knee, rectus femoris also steadies hip joint and helps iliopsoas flex hip joint

Question 16

What is the origin, insertion, innervation, and action of the Vastus Medialis?

Answer 16

Origin: Intertrochanteric line and medial lip of linea aspera
Insertion:common tendinous and independent attatchments to base of the patella
innervation: femoral nerve
action: extends knee, rectus femoris also steadies hip joint and helps iliopsoas flex hip joint

Question 17

What is the largest sesamoid bone in the body?

Answer 17
