  • Title: Patterned regeneration of internal femoral structures in the cockroach, Periplaneta americana L.
    Author: Kaars C, Greenblatt S, Fourtner CR.
    Journal: J Exp Zool; 1984 Apr; 230(1):141-4. PubMed ID: 6726144.
    Abstract:
    The morphology of the nerve and tracheal supply to the extensor tibiae muscle in normal legs was compared to that in regenerate legs. In normal femurs, the extensor nerve and trachea extend along the posterior surface of the extensor muscle. The nerve and trachea are closely associated and branch coincidently at regular intervals. In regenerate femurs, the nerve and trachea are not closely associated with each other, and both structures differ from normals in their branching patterns. The results suggest that tissue level interactions during regeneration differ from those during embryogenesis.
