1. how muscles work – in general muscles that move the mandible abdominal wall muscles anterior and posterior inferior and superior inguinal hernia’s muscles that move the humerus and scapula rotator cuff tears, impingement syndrome muscles that move the femur sprains, strains and “Charley horse” muscles that move the foot shin splints, anterior compartment syndrome Achilles tendon injuries

2. skeletal cardiacsmooth

3. Tendon Deep fascia Epimysium Epi = upon, above Perimysium Peri = around Endomysium Endo = within Connective tissue wrappings of skeletal muscle Myo, mys = muscle 1 muscle fiber = 1 muscle cell Muscle cells are multinucleated Working out Atrophy & aging Steroids

4. Bellies Insertion Origins Muscle attachments Ligaments: bone to bone Tendons: muscle to bone Attachments: Proximal Distal Direct Indirect

5. Aponeurosis Muscle to skin Muscle to muscle via tendon sheet

6. Muscle actions: agonist antagonist synergist fixator Biceps brachii Brachialis Triceps brachii

7. What does this muscle do? 1.Blink 2.Smile 3.Move your tongue 4.Move your neck 5.Chew 6.Not sure X

8. Mandibular fossa 1.Depress & elevate 2.Medial & lateral excursion 3.Protraction & retraction Moving the mandible

9. Temporalis Masseter attachments actions Medial pterygoid Lateral pterygoid Muscles that move the mandible

10. Depress mandible gravity digastric muscle geniohyoid & mylohyoid when hyoid is fixed

11. Temporalis massater Medial pterygoid Lateral pterygoid Mylohyoid Digastric

12. Rectus abdominis External oblique Internal oblique Transversus abdominis Attachments Actions Muscles that move (and protect) the abdomen/trunk

13. AB C D Rectus sheath ( aponeurosis ) Linea alba

14. Abdominal wall abdominal muscles back muscles quadratus lumborum Psoas (iliopsoas) diaphragm pelvic diaphragm “holes” in the wall hernia (hiatal) congenital or acquired

15. Important postural muscles normal rigidslumped

16. Spermatic cord Inguinal canal – men & women intestines Parietal peritoneum scrotum Inguinal hernia

17. attachments actions (on humerus) abduct (lateral fibers) flex, medially rotate (anterior fibers) extend, laterally rotate (posterior fibers) Deltoid

18. attachments actions flexion (agonist) adduction medial rotation elevate ribs

19. Subscapularis medially rotate Supraspinatus abduct Infraspinatus Extend Laterally rotate Teres minor adduct laterally rotate 4 Rotator cuff muscles

20. Scapula movers & stabilizers Levator scapulae elevate scapula flex neck Rhomboids retract elevate fix scapula rotate downward Trapezius elevate, rotate upward (S) retract (M) depress (I) extend neck flex laterally (one trap)

21. Trapezius Rhomboids Deltoid Teres major Triceps Latissimus dorsi Supraspinatus Infraspinatus Teres minor Subscapularis Levator scapulae

22. Impingement syndrome Rotator cuff tears

24. Hamstring group: flex knee, extend hip Muscle strains from quick extensions

25. G. minimus piriformis G. Medius G. Maximus Gluts: extend, abduct, laterally rotates femur Piriformis: abduct, laterally rotates femur

26. Iliotibial Band (IT band) G. Maximus Tensor Fasciae Latae flex femur abducts femur medially rotates femur stabilizes knee

27. Tensor Fasciae Latae (TFL) flex abduct med. rot Rectus Femoris flex hip extend knee Vastus lateralis vastus intermedius Vastus medialis extend knee Charley horse patella tracking Patellar tendon

28. Iliopsoas flex hip Adductors adduct femur flex hip flex knee (lateral rotation) Lateral rotators piriformis obturator externus Groin pull

29. Iliopsoas TFL Sartorius Adductors quads Glut max & medius hamstrings Piriformis Sciatic nerve

30. Achilles tendon calcaneus gastrocnemius Attachments of the gastrocnemius Attachments of the soleus Actions of the gastrocnemius 1.Flex the knee 2.Plantarflex the foot Actions of the soleus 1.Plantarflex the foot Ruptured Achilles tendon Pulled calf muscle

31. Tibialis anterior Attachments Actions Shin pain: Shin splints Compartment syndrome Tibialis Posterior

32. Intramuscular injection sites Deltoid muscleVastus lateralis Gluteal region- right side Left arm Right leg
