804. Thank you for this resource. I believe the answer should be E. According to the Papel text...
1) "By the ninth day the graft is firmly anchored by its new blood supply and fibrblast integration.
2) "Within 2 months neural structures begin to regenerate...""Skin grafts rarely attain normal sensory innervation after healing is complete." Therefore the answer E would be false and D would be a true statement
