Both the cardiac muscle and nervous tissue in the brain and spinal  cord have no functional regenerative capacity.
Regeneration Regeneration The embryo has the capacity to undergo regulative growth when cells or tissues are removed or rearranged. In the adult, regeneration can replace missing parts by growth and remodeling of somatic tissues. Newts have a great capacity for regeneration (i.e. regeneration of lens from iris epithelium). Mammals can regenerate liver & broken bones can mend but not lost limbs. Two main types of regeneration are: 1) morphoallaxis has little growth and depends upon re-patterning of tissues (as seen in Hydra) and. 2) epimorphosis depends upon growth of new and correctly patterned structures. Morphoallaxis: Hydra grows by loss of cells from its ends and by budding.
