  • 80. Embryonic Tissue
    • The earliest embryonic mesenchyme is very loose connective tissue
    • As it “builds,” it becomes more organized and even starts to identify areas where the skeleton will form
    www.freelivedoctor.com
  • 81. Embryonic Tissue
    • From the scleromyodermatome arise “muscles” sandwiched between
      • Bone (sclero-)
      • Skin (derma-)
    • This is the “origin” of the muscle.
    • It then grows to another bone, the “insertion”
    www.freelivedoctor.com
  • 82. Embryonic Tissue
    • There are two ways to get “skeleton”
    • Intramembranous Ossification
    • Endochondral Ossification
