The superfical anterior muscles

Concerned with flexion of the hip and extension of the leg.


Inguinal Ligament

Location: extending btwn the anterior superior iliac spine and the pubic symphysis.


Iliacus Muscle

A larger powerful muscle
Location: fills the upper two thirds of the iliac fossa and includes a tendon that merges with the psoas major muscle from the lumbar vertebrae to insert on the lesser trochanter of the femur


Psoas major and iliacus muscle (Function)

Act to flex the hip joint and rotate the thigh medially.


Psoas Minor

Location: originates from the 12th thoracic and 1st lumbar vertebrae
Function: acting to assist psoas major in flexion, absent in 40% of people.


Three strong adductor muscles

Medial to the psoas major
Pectineus, adductor longus, adductor magnus



Location: inserts below the lesser trochanter


Adductor Longus

Location: inserts at the mid-femur


Adductor Magnus

Location: extends from the greater tochanter all along the linea aspera to the adductor tubercle of the distal femur


THe adductor Brevis

Location: lies deep t the adductor longus



Location: arises from the anterior superior iliac spine to cross the thigh obliquely and attach to the upper medial segment of the proximal tibia.
Function: called the tailor's muscle due to its action in flexion of the thigh and leg with lateral rotation of the thigh


Gracilis Muscle

Location: attaching to the proximal medial segment of the tibia is the long slender muscle, extends from the pubic symphysis along the medial aspect of the thigh
Function: acts to flex and medially rotate the leg as well as adduct the thigh.
One of the muscles strained in "groin pulls"


Quadriceps femoris group

Rectus femoris, vastus lateralis, vastus medialis and (Deep) vastus intermedius.


Rectus Femoris

Location: arises from the anterior inferior iliac spine, and the only quadriceps muscle
Function: acts to flex the thigh


Vastus Muscles

Location: all arise from the femur, with the rectus femoris form the common quadriceps tendon suspending the patella. Ultimately insert into the tibial tuberosisty visa the patella ligament.


Quadriceps muscles

Function: act together in powerful extension of the leg


Fascia Lata

Function: sheet of connective tissue that wraps the muscles of the thigh like a stocking.
Location: extends from the inguinal ligament to enclose the gluteus maximus, cover the hamstrong, quadriceps and adductor muscles, to then end beyond the knee.


Iliotibial tract

Thick lateral edge, runs like a stripe on the pants of a uniform


Tensor Fascia Lata

Triangular muscle that originates from the outer lip of the iliac crest and inserts into the liliotibial tract
Function: acting to pull upon the tract and hence stabilizes the knee joint when it bears weight.
