+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 RotationMEDIAL

Adductors Magnus Longus Brevis

Semimembranosus Gluteus MediusLATERAL 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)
