Musculature of Pelvis and Thigh (page 4)

Flashcards covering key muscles involved in the musculature of the pelvis and thigh, including origins, insertions, and innervations.

Psoas Major

Originates from vertebral bodies T12 -L5 and inserts at the lesser trochanter of the femur; innervated by the lumbar plexus.

Iliacus

Originates from the iliac crest and fossa, sacral ala, and anterior sacroiliac ligaments; inserts at the lesser trochanter of the femur and psoas major tendon; innervated by the femoral nerve.

Tensor Fascia Latae

Originates from the iliac crest and anterior superior spine; inserts at the lateral condyle of tibia via the iliotibial band; innervated by the superior gluteal nerve.

Gluteus Medius

Originates from the ilium and inserts at the greater trochanter of the femur; innervated by the superior gluteal nerve.

Gluteus Minimus

Originates from the ilium and inserts at the greater trochanter of the femur; innervated by the superior gluteal nerve.

Gluteus Maximus

Originates from the ilium, sacrum, and coccyx; inserts at the lateral condyle of tibia via the iliotibial band and gluteal tuberosity of femur; innervated by the inferior gluteal nerve.

Sartorius

Originates on and below the anterior superior spine of ilium and inserts at the medial aspect of the tibial tuberosity; innervated by the femoral nerve.

Gracilis

Originates from the pubis and inserts at the medial aspect of the proximal tibia; innervated by the obturator nerve.

Semimembranosus

Originates from the ischial tuberosity and inserts at the medial condyle of the tibia, collateral ligament of the knee; innervated by the tibial nerve.

Semitendinosus

Originates from the ischial tuberosity and inserts at the medial shaft of the tibia near the tibial tuberosity; innervated by the tibial nerve.

Adductor Longus

Originates from the pubis and inserts at the linea aspera of femur; innervated by the obturator nerve.

Adductor Brevis

Originates from the pubis and inserts at the linea aspera of femur; innervated by the obturator nerve.

Pectineus

Originates from the pubis and inserts at the posterior aspect of the proximal femur; innervated by the femoral nerve.

Adductor Magnus

Originates from the ischium and pubis and inserts at the linea aspera of femur; innervated by the obturator and tibial nerves.

Vastus Intermedius

Originates from the anterior and lateral shaft of the femur; inserts at the tibial tuberosity; innervated by the femoral nerve.

Rectus Femoris

Originates from the anterior inferior spine of ilium; inserts at the tibial tuberosity; innervated by the femoral nerve.

Vastus Lateralis

Originates from the greater trochanter and linea aspera of the femur; inserts at the tibial tuberosity; innervated by the femoral nerve.

Vastus Medialis

Originates from the linea aspera of the femur; inserts at the tibial tuberosity; innervated by the femoral nerve.
