the upper outer quadrant
name the 3 muscles of the anterior hip
1. psoas major
2. Iliacus
3. iliopsoas(1&2 join)
what are the major actions of the anterior hip muscles
flexion of trunk, flexion of thigh
where does the psoas major orgiginate
all lumbar vertebrae
where does the psoas major insert
lesser trochanter of femur
where does the iliacus originate
iliac fossa
where does the the iliacus insert
lesser trochanter of femur
what important landmark structure divides the trunk and thigh on the anterior iliac region
the inguinal ligament
where do the psoas major and illacus join
after passing under the inguinal ligament
what is the major action of the iliopsoas
major flexor of the hip
what muscle exists only 60% of the time? what action can it perform
the psoas minor. does not cross hip joint so can only perform minor flexion of the trunk
How many groups of muscles surround the femur? How are they separated
3 groups. Anterior, medial, and posterior groups separated by connectivetissue sheets
What is the major action of the anterior thigh muscles
extensors of the leg

(sartorius flexes)
name the 5 muscles of the anterior thigh region
1. sartorius
2. rectus femoris
3. vastus lateralis
