Flashcards in Superficial Anterior Thigh Muscles (Right side) Deck (19)
The superfical anterior muscles
Concerned with flexion of the hip and extension of the leg.
Location: extending btwn the anterior superior iliac spine and the pubic symphysis.
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.
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
Location: inserts at the mid-femur
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
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.
Location: arises from the anterior inferior iliac spine, and the only quadriceps muscle
Function: acts to flex the thigh
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.
Function: act together in powerful extension of the leg
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.
