+Homework Review

Upper Extremity Worksheet

+Movements of the Hip

What are the movements of the hip? Flexion Extension Abduction Adduction Medial Rotation Lateral Rotation Circumduction

+Muscles of Hip Flexion

Rectus Femoris (quad muscle)

Pectinius

Psoas Major

+Muscles of Hip Extension

Gluteus Maximus

Hamstrings Semimembranosus Semitendinosus Biceps Femoris

+Muscles of Hip Abduction

Tensor Fascia Latae

Iliotibial Band (IT Band)

+Muscles of Hip Adduction

Adductor Magnus

Adductor Brevis

Adductor Longus

+Muscles of Medial/Lateral Rotation

MEDIAL Adductors

Magnus Longus Brevis

Semimembranosus Gluteus Medius

LATERAL Biceps femoris

+Psoas Major

Origin: T12 and lumbar vertabrae

Insertion Lessor trochanter of femur

Action Flexor of hip or thigh on pelvis

+Semimembranosus

(Deep to Semitendinosus)

Origin: Ischial tuberosity

Insertion: Proximal tibia

Action: Extends thigh; flexes knee, medially rotates

+Tensor Fascae Latae

Origin: Iliac crest

Insertion: IT band tract

Action: Medial rotation, abduction

+Tensor Fasciae Latae

+Adductor Magnus

Origin: Ischial and pubic rami

Insertion: Adductor tubercle of femur

Action: Adduct and medially rotate and flex thigh

+Adductor Magnus

+IT Band Syndrome

IT Band connects from the Tensor Fascae Latae to the Lateral knee

Very important in leg stabilization while running

Common injury to the IT band from running, cycling, and heavy squatting

Inflammation caused by continual rubbing of IT band over lateral femoral epicondyle from flexion/extension

+

Quad/Knee/Calf

+Movements of the Knee

What directions does the knee move? Flexion Extension

NO rotation

+Muscles of Knee Flexion

Remember, flexion is the decrease in angle size Heel to butt

3 Hamstring muscles Semimembranosus Semitendinosus Biceps Femoris

+Muscles of Knee Extension

How many muscles are in the quadriceps? 4

Rectus Femoris

Vastus Medialis

Vastus Lateralis

Vastus Intermedius

+Muscles of the Calf (action)

Calf muscles deal with ankle movement Gastrocnemius (plantar flexion)

Crosses ankle and knee Solus (plantar flexion)

Crosses only ankle

Say you have a tight calf, but you are unsure which muscle to stretch. How could you stretch one and not the other? (HINT: Has to do with what joints they cross)
