skeletal system/tissues, joints and skeletal muscle (Skeletal…

- - - - framework for soft tissue connection
    - - along with muscle
    - - cranium, vertebrae, rib cage
    - - calcium & phosphorus
    - - inside bone
    - - fat-nutrient; yellow marrow
  - - - periosteum: place of attachment for ligaments and tendons; ferforating fibers
      - Periosteum: 2 layers- outside D.I.C.T & inside: cellular layer, osteogenic
      - Epiphyses>articular cartilage: made up of hyaline cartilage
      - Epiphyseal line= stop growing
  - - - CB: made of osteons
      - periosteum covers bones
    - - endosteum covers the trabeculae
  - - - create extracellular matrix
    - - fusion of several leukocytes; multinucleate, large, microvilli, mobile
    - - found in periosteum and endosteum
    - - maintain healthy bone tissue; located in trabeculae
- - - - Mostly reticular fibers& blood vessels within; loose connective tissue
    - - around each fascicle; D.I.C.T
    - - around each muscle organ; D.I.C.T
    - - around several muscles that often work together (D.I.C.T.)
  - - - cell membrane
    - - Invagination of the sarcolemma
    - - Smooth E.R; terminal cisterns, storage place for calcium
    - - Organelles
    - - ATP; powerhouse of the cell
- - - - bursa- fibrous sack filled with synovial fluid; makes movement smooth
        
        specialized bursa: tendon sheath; location: wrists, ankles, fingers, toes
  - - - Gliding
      - intercarpal joints, intertarsal joints, joints b/w vertebral articular surfaces
    - - Flexion and Extension
      - elbow joints, interphalangeal joints
    - - Rotation
      - proximal radioulnar joints, atlantoaxial
    - - flexion & extension; adduction and abduction
      - Metacarpophalangeal joints (knuckles), wrist joints
    - - Adduction and Abduction; flexion and extension
      - carpometacarpal joints of the thumbs
    - - Rotation, flexion, extension, adduction, abduction
      - shoulder and hip joints
