Kylie Fraile P.5 The Skeletal System - Coggle Diagram

- - - - Gomphoses: peg in socket joints, fibrous connection ex) periodontal ligament, holds teeth in alveolor socket only example
      - Syndesmoses: bones connected by ligaments ( bonds of fibrous tissue) fiber length varies and so does movement EX) inferior tibiofibular joint:
      - Sutures: rigid, interlocking joints of skull, allows growth during youth, short ct fibers allows expansion, middle age sutures ossify & fuse, closed immovable - synotoses
    - - Synchondroses: bar/plate of hyaline cartilage, unites, bones, almost all immovable ex) epiphyseal plate joints
      - Symphyses: fibrocartilage unites bones in symphysis joint, strong slightly moveable, EX) pubic symphysis
    - - Diff types of ligaments: capsular: thickened part of firbous layer Extracapsular: outside capsule Intracapsular: inner
      - Nerves & Blood vessels: nerves detect pain, watch position and strength, capillary beds supply filtrate for fluids, fatty pads, cushioning between layer of capsule and synovial members, menisci
      - Articular, joint, capsule: 2 layers thick External Fibrous layer: dense ireeg ct Inner synovial layerloose ct makes up fluid
      - Synovial fluid, viscous filtrate of plasma & hyaluronic acid, lubricated articular cartilage, phagocytic cells to remove debris
      - Joint cavity: small fluid filled potential space ONLY SYNOVIAL JOINTS HAVE CAVITIES
      - articular cartilage: hyaline cartilage covers ends of bones and prevents friction
      - Have bursae & tendon sheaths
      - types: plane (nonaxial movement, gliding, intercarpal joints) hinge (uniaxial, flexion & extension, elbow joints) pivot (uniaxial, rotation, proximal radioulnar) Condylar( biaxial, flexion, extension, abduction, adduction) saddle ( biaxial, adduction, abduction, flexion, extension, joints of the thumb) Ball and socket ( mulitaxial, flexion, extension, abduction, adduction, rotation, shoulder and hip joints)
