    (ball and socket joint)
  6. What is a TROCHOIDAL joint?
    section of a cylinder of one bone fits into a corresponding cavity on the other, as in the proximal articulation between the radius and ulna. same as a pivot joint, rotary joint.(pivot)
  7. What is a ARTHRODIAL joint?
    a synovial joint in which the opposing surfaces are nearly planes and in which there is only slight gliding motion. plane joint.(gliding)
  8. What is a ATLANTOAXIAL joint?
    pivot joint (such as the vertebrae)
  9. What is a SELLAR joint?
    same as a saddle joint
  10. What is a UNIAXIAL joint?
    contains one axis of rotation, one plane.
  11. What is a BIAXIAL joint?
    Contains two axes of rotation, two planes.
  12. What is a TRIAXIAL (POLYAXIAL OR MULTIAXIAL) joint?
    Contains three axes or rotation, three planes.
  13. What is a NONAXIAL joint?
    Does not occur about an axis, instead involves gliding movements.
  14. What is a GOMPHOSIS joint?
    An immovable articulation in which a hard part is received into a bone cavity. (As the teeth into the jaw, tooth socket)
  15. What is a SUTURE joint?
    The line of junction or an immovable joint between two bones, especially of the skull.
  16. What is a SYNCHONDROSIS joint?
    A rigid union between two bones formed either by hyaline cartilage or by fibrocartilage. (such as sostochondral joints)
  17. What is a SYMPHYSIS joint?
    A form of cartilaginous joint in which union between two bones is effected by fibrocartilage without a synovial membrane.(such as symphysis pubis)
  18. What is the ATLANTOOCIPITAL joint?
    one of a pair of condyloid joints formed by the articulation of the atlas of the vertebral column with the occipital bone of the skull. It includes two articular capsules, two membranes, and two lateral ligaments. The atlantooccipital joint permits nodding and lateral movements of the head.
