1 Muscles of the Hip/Thigh

2 Is “Snoozing” Bad? button/index.html?hpt=he_t4

3 Homework Review Upper Extremity Worksheet

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

5 Muscles of Hip Flexion Rectus Femoris (quad muscle) Pectinius
Psoas Major

6 Muscles of Hip Extension
Gluteus Maximus Hamstrings Semimembranosus Semitendinosus Biceps Femoris

7 Muscles of Hip Abduction
Tensor Fascia Latae Iliotibial Band (IT Band)

8 Muscles of Hip Adduction
Adductor Magnus Adductor Brevis Adductor Longus

9 Muscles of Medial/Lateral Rotation
Adductors Magnus Longus Brevis Semimembranosus Gluteus Medius LATERAL Biceps femoris

10 Psoas Major Origin: T12 and lumbar vertabrae
Insertion Lessor trochanter of femur Action Flexor of hip or thigh on pelvis

11 Semimembranosus (Deep to Semitendinosus) Origin: Ischial tuberosity
Insertion: Proximal tibia Action: Extends thigh; flexes knee, medially rotates

12 Tensor Fascae Latae Origin: Iliac crest Insertion: IT band tract
Action: Medial rotation, abduction

13 Tensor Fasciae Latae

14 Adductor Magnus Origin: Ischial and pubic rami
Insertion: Adductor tubercle of femur Action: Adduct and medially rotate and flex thigh

15 Adductor Magnus

16 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

17 Quad/Knee/Calf

18 Movements of the Knee What directions does the knee move? NO rotation
Flexion Extension NO rotation

19 Muscles of Knee Flexion
Remember, flexion is the decrease in angle size Heel to butt 3 Hamstring muscles Semimembranosus Semitendinosus Biceps Femoris

20 Muscles of Knee Extension
How many muscles are in the quadriceps? 4 Rectus Femoris Vastus Medialis Vastus Lateralis Vastus Intermedius

21 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)

22 Injuries of the Knee/Calf

23 Injuries of the Knee Patella Tracking Syndrome
Patella Tendonitis (Jumper’s Knee) Medial Tibial Stress Syndrome Shin Splints Achilles Rupture

24 Patellar Tracking Syndrome

25 Patellar Tendonitis

26 Medial Tibial Stress Syndrome

27 Achilles Rupture
