skeletal - Coggle Diagram

- - - - long with expanded ends
      - Ex: arms/ legs
      - stucture
        
        Expanded ends of bones(epiphyses)
        
        coat epiphyses(Articular cartilage)
        
        shaft (diaphysis)
        
        cover bone dense connective tis =(periosteum)
        
        diaphysis contains hollow chamber (medullary
        cavity)
        
        medullary cavity is lined (endosteum)
        
        medullary cavity filled connective
        tis (bone marrow)
        
        (projections) provide attachment tendons/ ligaments /openings or grooves for blood vessels and nerves
        
        (Compact bone) tightly packed tissue=diaphysis wall
    - - almost equal in length and width
      - Ex: wrist and ankles
    - - plate-like shape with broad surface
      - Ex: ribs,
        scapula, flattened skull
    - - varied shape
      - Ex: vertebrae, some facial
  - - - Sacrum:
        
        skinner
        
        less sharp
      - pelvic cavity:
        
        smaller cavity
        
        distances between ischial spines/ ischial
        tuberosities smaller
      - pelvic girdle:
        
        smaller pubic arch
        
        oval obturator foramina
        
        smaller pubic arch
      - coccyx:
        
        less motion
    - - pelvic cavity:
        
        cavity is wider/shorter/ roomier
        
        distances between ischial spines/ ischial
        tuberosities = greater
      - pelvic girdle:
        
        lighter, thinner, and have less evidence of muscular attachments
        
        obturator foramina triangular
        
        acetabula are smaller and the pubic arch is wide
      - Sacrum:
        
        wider
        
        sacral curvature is bent sharp
      - coccyx:
        
        coccyx is more movable
- - - - Hinge
        
        Movement: Flexion and extension
        
        articulates w concave surface another
      - plane
        
        Movement: Sliding or twisting
        
        nearly flat or slightly curved
      - Pivot
        
        articulates with a ring bone
        
        Movement: Rotation around a central
        axis
      - Condylar
        
        Movement: variety (two planes) no rotation
        
        articulates with elliptical cavity of
        another
      - saddle
        
        Movement: variety two planes
        
        surface of one bone fits the
        complementary surface of another.
      - Ball-and-socket
        
        ball and cup interjoining joint
        
        Movements: all planes/ rotation
