  Wormhole solutions in classical General Relativity are unstable and hence non
traversable. Morris and Thorne discovered a traversable wormhole solution that
required the energy momentum tensor of matter sources to violate various energy
conditions and are out of the purview of the standard model of particle
physics. The search for traversable wormhole solutions in Modified Theories of
Gravity has been of significant interest in the decades after Morris and Thorne
first published their results as such violations may be avoided in such
theories. This work comprehensively reviews traversable wormhole solutions in
modified theories of gravity with extra dimensions that satisfy the various
energy conditions with an in depth look at the matter sources and the various
constraints on the parameters of the theory to make the energy momentum of the
matter sources respect the energy conditions.
