  1. arthrology
    the scientific study of joints
  2. kynesiology
    the study of human movement
  3. articulation or arthrosis
    the poin in contact between two bone or between bone and teerh
  4. what are the different kinds of structures of joints classified as
    fribrous, cartilagenious and synovial joints
  5. describe a fibrous joint
    there is no synovial cavity and bones are held together by dense regular connective tissue
  6. describe cartilagenious joints
    there is no synovial cavity and the bones are held together by cartilage
  7. describe synovial joints
    the bones forming the joints have a synovial cavity and are united by the dense irregular connective tissue of and articular capsule and also by acessory ligaments.
  8. what are the types of movements that joint may permit called
    synarthrosis, diarthroses and amphiarthroses
  9. synarthrosis
    is an immovable joint the types of joints that fall in this category are fibrous joints and some cartilagnious joints.
  10. amphiarthroses
    is a slightly movable joint mostly cartilageious joints and some fibrous joints.
  11. diarthroses
    is a freely movable joint its usually synovial joint have a diarthroses function.
  12. the three types of fibrous joints
    are sutures syndesmosis and interoseus membranes
  13. what is a suture
    a suture is a fibrous joint composed of thin layer of dense irregular connective tissueand they only occur between bones of the skull
  14. what are the different formations of a suture
    serrate sutrure, squamos suture and plane suture
  15. what is a serrate suture
    its a common type of suture in which the margins of the suture are interlocking like a zipper.
  16. what is a squamos suture
    a squamos sutue is a suture in which its margins just over lap each other the only suture that does this is the lambdoid suture.
  17. what is a plane suture
    a plane suture is similar to a serrate suture but doesnt contain interlocking margins like the suture of the hard plate or maxilla
  18. what is synastosis
    the fusion of two seperate bones fused into one like the fontanels of the frontal bone.
  19. what is a frontal or metopic suture
    this type of suture occurs when the fontanels of the frontal bone do not under go synastosis before the age of six if it is pass the age of six it is called the frontal or metopic suture.
  20. syndesmosis
    is a tpe of fibrous joint syndesomsis is when their is a great amount of distance between two bone that are held by dense irregular connective tissue for example like the space between the tibia and the fibula.
  21. gomphoses
    is a type of fibrous joint in which holds teeth together.
  22. what are the two kinds of cartilignois joints
    synchondrosis and symphisis
  23. whats synchondrosis
    a synchondrosis is a cartilage joint in which the cartilage meterial is hyalincartilage like the epiphyseal growth plate this is a synarthrosis joint.
  24. what is a symphisis
    an amphiarthroses cartilagenious joints that is found only at the midline of the skeletal structure.
  25. articular cartilage
    articular cartilage is is found in synovial joints and they are located at the ends of each connecting bone to reduce friction, absorbs shock and it gets its nutrients through diffusion.
  26. articual capsule
    sorrounds the ynovial joint and it enclsose the synovial cavity they are composed of two layer and oute fibrous joint and an intersynovial membrane.
  27. fibrous memebrane
    is the outer layer of an articulating capsule which is made of dense egualr conncting tissue that is connecting between the two bones called ligaments. poorly vascularized but well innervated
  28. intersynovial membrane
    the inner portion of the articular capsole that is composed of areolar connective tissue with elastic fiber it contains articular fat pads. well vascularized but poorly innervated.
  29. synovial fluid
    is similar to plasma but contains hyalronic acid and glycoprotine that makes up lubricin. it function is to reduce friction by lubricating joints absorbing shocks and transfer of nutrients and eliminationg carbon dioxide and metabolic waste.
  30. the types of accesory ligaments
    extrascapsula ligaments and intrascapsula igaments
  31. what is extrascapsular ligaments
    lye outside the articular capsule
  32. what is intrascapsular ligament
    a ligament that is inside the articular capsule.
  33. articular disc or minisci
    crescent shape pads between the two bones that are shock absorbers better fit articulating bone surfaces. help for adaptable movements and hight and weight distribution over a great contact surface and also distribution between synovial lubricant.
  34. what is labrum
    part of a synovial joint in which helps deepned the joint of of a ball and socket type joint structure like the sholder and hip to help prevent dislocation.
  35. bursae
    are sac like structures that strategically situated to eleviat friction from synovial joints they are similar to small amounts of lfued that are similar to synovial flued bursae can be locted between skin and bones, muscles and bones or ligaments and bones to helps cusion movements
  36. tendon sheaths
    tubelike bursae that wrap around certain tendons to help reduce friction of a synovial joint
  37. bursitis
    an acute or chronic inflamation that is usually caused by irritation an repeatedexcessive exzertion of a jointwhich give them pain swelling tenderness and limitied movment
