Superficial Anterior Thigh Muscles (Right side)

Question 1

The superfical anterior muscles

Answer 1

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

Question 2

Inguinal Ligament

Answer 2

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

Question 3

Iliacus Muscle

Answer 3

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

Question 4

Psoas major and iliacus muscle (Function)

Answer 4

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

Question 5

Psoas Minor

Answer 5

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

Question 6

Three strong adductor muscles

Answer 6

Medial to the psoas major

Pectineus, adductor longus, adductor magnus

Question 7

Pectineus

Answer 7

Location: inserts below the lesser trochanter

Question 8

Adductor Longus

Answer 8

Location: inserts at the mid-femur

Question 9

Adductor Magnus

Answer 9

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

Question 10

THe adductor Brevis

Answer 10

Location: lies deep t the adductor longus

Question 11

Sartorius

Answer 11

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

Question 12

Gracilis Muscle

Answer 12

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”

Question 13

Quadriceps femoris group

Answer 13

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

Question 14

Rectus Femoris

Answer 14

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

Question 15

Vastus Muscles

Answer 15

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.

Question 16

Quadriceps muscles

Answer 16

Function: act together in powerful extension of the leg

Question 17

Fascia Lata

Answer 17

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.

Question 18

Iliotibial tract

Answer 18

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

Question 19

Tensor Fascia Lata

Answer 19

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.
