Presentation Transcript

  1. Muscles Prime Mover = responsible for movement i.e. Biceps brachii = forearm flexion Antagonists = resists movement of prime mover i.e. Triceps brachii = forearm extension Synergists = Aid prime movers i.e. Brachioradialis for forearm flexion

  2. Muscles • Of the head and face 2. Of the pectoral girdle & arms 3. Of the thorax & abdomen 4. Of the pelvic girdle & legs

  3. Muscles of Face & Mastication

  4. Epicranial aponeuroses Frontalis Occipitalis

  5. Orbicularis oculi Orbicularis oris Zygomaticus major Buccinator

  6. Temporalis Masseter Sternocleidomastoid Splenius capitis

  7. Orbicularis Oculi Zygomaticus major Orbicularis Oris Buccinator

  8. Muscles that move Pectoral Girdle 1 = pectoralis minor (depresses scapula) 2 = Serratus Anterior (pulls scapula anteriorly)

  9. Supraspinatus (abducts arm) Deltoid (Removed) Infraspinatus (rotates arm laterally) Teres Minor (rotates arm laterally) Teres Major (rotates arm medially & adducts arm) Posterior Arm Muscles that move arm

  10. Subscapularis (rotates arm medially) Biceps Brachii (flexes elbow & rotates hand laterally) Anterior Arm

  11. 1 & 2 = Iliopsoas group 3 = Sartorius 4 = Rectus Femoris 5 = Vastus Lateralus 6 = Vastus Medialus 7 = Gracilis Anterior Thigh Muscles

  12. 1 = Gluteus maxiumus 2 = Semitendinosis 3 = Biceps femoris 4 = Vastus lateralus Lateral Thigh

  13. Anterior Thigh

  14. Posterior Thigh

  15. Medial Thigh

  16. 1 = Gastrocnemius 2 = Tibialis Anterior 3 = Soleus Medial Leg
