Document Summary
Embryology and development part 3 (slide: limb bud development) Upper limbs ~24 days; both upper and lower at 28 days (*embryonical days not. Apical ecto ridge like a cap over limb bud. Chemical signal to start outward growth of limbs. Start proximal and grow towards digitals gotta make sure its being supplied by blood. At the same time; filling with bone, muscle, tissue. We tend to build things that we break down later. Protein that stimulates development of outward growth looks like a hedgehog. Important to build good blood supply for proper formation. *chart in textbook for day by day development. Used for cancer stops blood supply for tumor. Everything gets pushed from lateral side to medial area to make the face. Between lip and nose structure: frontonasal: nasal placodes > nose, max: lateral to anterior medial > upper lip and upper jaw.
