  4. The muscle name biceps means it has 2 ____________. origins

  5. When a muscle contracts and shortens, its ________ is pulled toward its _________. insertionorigin

  6. Masseter

  7. Temporalis

  8. Buccinator

  9. What is the term that refers to a ring of muscle that contracts to close an opening; it works much like a drawstring? sphincter

  10. The epicranius consists of what 2 muscles? Frontalis Occipitalis

  11. What is the primary function of the orbicularis oris? closes and protrudes the lips

  12. Zygomaticus

  13. Platysma Known as the pouting muscle

  14. When you clench your mouth hard, what muscle is the prime mover that can be palpated in the cheek area? masseter

  15. The primary function of the frontalis working with the occipitalis is to __________________________. raises eyebrows and creates wrinkles in forehead

  16. Orbicularis oris

  17. What is the primary function of the zygomaticus? raises the corner of the mouth; smiling

  18. Name the Skeletal Muscle Actions: • = decreasing the angle between 2 bones • = decreasing the angle between the foot and shin; • = pointing toes; • = increasing the angle between 2 bones • = moving a body part away from the midline • = moving a body part toward the midline Flexion Dorsiflexion Plantar flexion Extension Abduction Adduction

  19. Frontalis

  20. What are muscles called that contract to stabilize nearby joints? Synergists

  21. Lateral pterygoid Lateral pterygoid

  22. What is the primary function of the orbicularis oculi? Close eyes

  23. Medial pterygoid

  24. The ____________ of a muscle is its immovable (anchored) end. origin

  25. Orbicularis oculi

  26. Buccinator Also known as the “trumpeter’s muscle”

  27. TMJ The primary muscles involved are the following: temporalis, masseter, medial pterygoid, and lateral pterygoid Name the muscles involved with TMJ.

  28. = movement in a circular (cone- shaped) motion = turning movement of a bone about its long axis; (i.e.atlas/axis) = turn at elbow so palms are up = turn at elbow so palms are down = sole of foot in = sole of foot out = lifting a body part; (i.e. shoulder shrug) = returning a body part to pre-elevated position. Circumduction Rotation Supination Pronation Inversion Eversion Elevation Depression

  29. Give the term for the Relative Size of a muscle • = largest • = longest • = shortest maximus longus brevis

  30. Frontalis Name the muscle that does this action.

  31. Name muscles of facial expression. Orbicularis oculi Orbicularis oris Epicranius (frontalis and occipitalis Buccinator Zygomaticus platysma
