Muscle Anatomy

Front

Tensor fascia lata

Back

helps to flex the hip, move the leg outward (abduction), rotate the leg inward, and stabilize the knee during activities like walking or running.

P: Iliac crest and lateral surface of anterior superior iliac spine

D: Iliotibial band

Front

Gluteus maximus

Back

The largest and most superficial of the three gluteal muscles, responsible for movement of the hip and thigh.
Extends thigh; laterally rotates thigh

P: Iliac crest, sacrum, coccyx

D: Iliotibial tract of fascia lata; linea aspera and gluteal tuberosity of femur

Front

Gluteus medius

Back

Abducts thigh; medially rotates thigh

P: Posterior iliac crest; lateral surface between posterior and anterior gluteal lines

D: Greater trochanter of femur

Front

Iliopsoas (iliacus and psoas major)

Back

A group of two muscles that are the primary flexors of the hip joint. Allows to lift your leg or bend at the waist.

P: Iliac fossa and major Transverse processes and bodies of T12 –L5 vertebrae for major

Front

Obturator externus

Back

A muscle located in the pelvis that helps in the lateral rotation of the thigh.

Front

Biceps femoris

Long Head & Short head

Back

Extends thigh (long head only); flexes leg at the knee joint

(both long head and short head); laterally rotates leg when flexed at knee.

P: Long head: Ischial tuberosity Short head: Linea aspera of femur

D: Head of fibula

Front

Vastus lateralis

Back

the vastus lateralis is on the outside of the thigh and helps with knee extension and stability.



P: greater trochanter and the lateral side of the femur (thigh bone)

D: connects to the patellar tendon, which then attaches to the kneecap (patella) and helps extend the knee.

Front

Vastus intermedius

Back

vastus medialis is on the inside of the thigh and also helps extend the knee while focusing on stability.

P: at the medial (inner) side of the femur, from the intertrochanteric line and the medial supracondylar line.


D: also attaches to the patellar tendon, which connects to the kneecap (patella) and assists in extending the knee

Front

Tibialis anterior

Back

Dorsiflexes foot; inverts foot

P: Lateral condyle and proximal shaft of tibia; interosseous membrane

D: Metatarsal I and first (medial) cuneiform

Front

Gastrocnemius

Back

Flexes leg at the knee joint; plantar flexes foot

P: Superior posterior surfaces of lateral and medial condyles of femur

D: Calcaneus (via calcaneal tendon)
