    • obliquus capitis inferior and obliquus capitis superior

    innervated by the suboccipital nerve.
  18. nerves which innervate the splenis capitis and splenius cervicis are
    the posterior or dorsal rami of the cervical spinal nervers
  19. the medial lateral pectoral nerves innervate the
    pectoralis major
  20. the long thoracic nerves innervates
    the serratus anterior

    the subclavius
  23. the insertion of the pectoralis major includes the
    bicipital groove.

  26. proximal
    closer to the trunk
  27. distal
    farther from the trunk
  28. condyloid / ellipsoid joint
    A BI-Axial Joint MCP joint
  29. MCP JOINT (Metacarpophalangeal joint)
    The metacarpophalangeal joints (MCP) are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the first phalanges, with the exception of that of the thumb, which presents more of the characters of a ginglymoid joint[1]. Arthritis of the MCP is a distinguishing feature of Rheumatoid Arthritis, as opposed to the distal interphalangeal joint in osteoarthritis.
  30. synarthroses
    A synarthrosis is a type of joint which permits very little or no movement under normal conditions. Most synarthrosis joints are fibrous

    An Uni-Axial joint. ball and socket joint (elbow)
  33. what is a condyle
    A rounded protuberance at the end of some bones, forming an articulation with another bone.

  37. Sphenoid bone has what processes?
    Pterygoid Processes
  38. sagittal plane
    the plane that divides the body into two side parts
  39. Frontal Plane
    The plane which divides the body into front and back parts
  40. Transverse Plane
    The plane which divides the body into top and bottom parts

  43. Origin
    The tendon attachment at the stable bone; proximal at limbs

  45. muscle belly
    is a the "fleshy" part of a muscle between th origin and the insertoin.
  46. Antagonist
    Muscle apposing the prime mover.
  47. Agonist
    The PRIME mover
  48. Third class Lever
    is the most common lver in the body. Mechanical advantage is speed.
  49. First class lever
    • SEE-SAW
    • Fulcrum is between effort and resistance.
    • Mechanical advantage is BALANCE.
  50. The ball and socket joints are synovial Joints
  51. Fixators stabilize the origin of th prime mover
  52. Plantarflexion
    Flexion of a foot or hand, or of their digits. That is, bending fingers or toes towards the lower surface of the foot or hand. For example, bending the foot in the direction of the plantar surface, as when standing on your toes - as opposed to ones heels
  53. TONE
    • Even when a whole muscle is not contracting, a small number of its motor units are involuntarily activated to produce a sustained contraction of the muscle fibers. The process gives rise to muscle tone.
    • To sustain muscle tone, small groups of motor units are alternately active and inactive in a constantly shifting pattern. Muscle tone keeps skeletal muscles firm, but it does not result in a contraction strong enough to produce movement.
  54. Laminae and pedicles
    form arches of vertebral canal
  55. intervertebral disc
  56. what is a spinous process?
    thorn shaped medal posterior process.
  57. transverse processes is a
    • Lateral posterior processes.
    • Forms "T" shape on the spine.
  58. the function of ligaments is
    to attach bones to bones
  59. tendons
    attach bones to bones and allows muscles to move.
  60. L1-L5
    Has small body and transverse foramina.
  61. the insertion of the rhomboids is the
    medial boarder of scapula
