Hip Internal Rotation

-Gluteus Minimus

Hip Flexion

-Psoas -Iliacus (Iliopsoas) -Rectus Femoris -Pectineus

Muscles of the posterior compartment

-hamstring group •Biceps femoris •Semitendinosus •Semimembranosus

Muscles in the medial compartment

-primarily adductors •Adductor brevis •Adductor longus •Adductor magnus •Gracilis

Muscles in the anterior compartment

-primarily knee extensors •Rectus femoris •Vastus medialis •Vastus intermedius •Vastus lateralis •Sartorius

Hip Adduction

-Adductor Brevis -Adductor Longus -Adductor Magnus -Gracilis

Hip Extension

-Gluteus Maximus -Biceps Femoris (Long Head) -Semitendinosus -Semimembranosus

Hip External Rotation

-Gluteus Maximus -Six Deep External Rotators

Hip Abduction

-Gluteus Medius

Identify movements of joints (pictures)

Flexion, extension, abduction, adduction, internal and external rotation, diagonal adduction and abduction, anterior and posterior pelvic rotation, right and left lateral pelvic rotation, right and left transverse pelvic rotation

What does pelvic rotation help to increase in kicking?

Greater kick distance and speed

At which three other joints does movement occur during pelvic rotation?

Right hip, left hip, lumbar spine

Know joints involved/type (Multiple Choice)

acetabulofemoral joint- enarthrodial symphysis pubis- amphiarthrodial sacroiliac joint- amphiarthrodial

Why is the structure of the hip joint relatively stable?

bony architecture, strong ligaments, large supportive muscles

What three movements is the sartorius involved in that gives it the name the "tailor's" muscle?

hip flexion, external rotation, knee flexion

In which tight muscle does compression of the sciatic nerve sometimes occur?

piriformis

What muscle is important in helping direct the leg forward so the foot is placed straightforward in walking and running?

tensor fascia latae
