  1. Skeletal Muscle Groups Movement

  2. Head and Neck • Facial muscles • Orbicularis oculi= circular muscle around the eye • Orbicularis oris= circular muscle around the mouth • Zygomaticus=smiling muscles • Masseter=mastication • Temporal= mastication

  3. Head and Neck • Sternocleidomastoid: flexes head • Trapezius: shrugs shoulders, extends head

  4. Upper Extremities • Pectoralis major: flexes upper arm (chest muscle) • Latissimus Dorsi: extends upper arm (on back) • Deltoid: abducts upper arm • Biceps Brachii: flexes forearm • Triceps Brachii: extends forearm

  5. Trunk/Torso • Abdominals: • Rectus Abdominus (6pack) • External Oblique (R & L flank) • Internal Oblique • Transverse Abdominis

  6. Respiratory Muscles • Intercostals (between each rib) • Diaphragm

  7. Muscles that move lower extremities • Gluteus Maximus: extends thigh • Adductor Muscles: adducts thighs • Hamstring Muscles: • Semimeeembraneous • Semitendinosus Flexes Lower Leg • Biceps Femoris

  8. Quadriceps femoris Extends lower leg: • Rectus femoris • Vastus Lateralis • Vastus intermedius • Vastus medialis

  9. Muscles of lower leg • Tibialis anterior: dorsiflexes foot • Gastrocnemius: plantar flexes foot • Peroneus Group: flexes foot

  10. Types of Movements • Flexion: decreases the angle between 2 bones at the joint.. (Bending0 • Extension: increases the angle between 2 bones at the joint…(straightening) • Abduction: movement away from the midline • Adduction: Movement toward the midline

  11. Types of Movement Rotation: movement around a longitudinal axis Hand positions that results from rotation of the forearm. Supination Pronation
