Thigh Flashcards
What are the three muscular compartments of the thigh?
1) anterior
2) medial
3) posterior
What nerve innervates the anterior muscle compartment of the thigh?
femoral nerve
What muscles are in the anterior muscle compartment of the thigh?
1) iliopsoas
2) quadriceps
What are the muscles making up the iliopsoas?
1) Psoas major
2) Iliacus
O: Psoas major
lumbar vertebrae
I: Psoas major
merges with iliacus –> lesser trochanter of femur
F: Psoas major
prime mover for flexion of hip joint
N:Psoas major
branches of lumbar plexus
O: Iliacus
Iliad fossa of hip bone
I: Iliacus
merges with psoaes major -> lesser trochanter of femur
F: Iliacus
prime mover for flexion of hip joint
N: Iliacus
branches of lumbar plexus
O: Quadriceps
hip bone and shaft of femur
I: Quadriceps
patella (indirectly to tibial tuberosity)
F: Quadriceps
prime mover for extension of knee joint
N: Quadriceps
femoral nerve
What are the muscles of the medial muscle compartment of the thigh?
1) Adductor magnus
What nerve innervates the medial muscle compartment of the thigh?
N: obturator nerve (branch of lumbar plexus)
What plexus is the obturator nerve a branch of?
Lumbar flexus
O: Adductor magnus
pubic bone and ischium
I: Adductor magnus
linea aspera and adductor tubercle
F: Adductor magnus
prime mover for adduction of hip joint
N: Adductor magnus
obturator AND sciatic nerve
What are the muscles of the posterior muscle compartment of the thigh?
1) Biceps femoris
