  In this manuscript, we construct generalized Ellis-Bronnikov wormholes in the
context of $f(R)$ modified theories of gravity. We consider that the matter
driving the wormhole satisfies the energy conditions so that it is the
effective energy-momentum tensor containing the higher-order derivatives of
curvature terms that violate the null energy condition. Thus, the gravitational
fluid is interpreted by the higher-order derivatives of curvature terms to
represent the wormhole geometries and is fundamentally different from its
counter representation in general relativity. In particular, we explore the
wormhole geometries by presuming various well-known forms of Lagrangian $f(R)$.
In addition, for the seek of completeness, we discuss modified
Tolman-Oppenheimer-Volkov, volume integral quantifier, and total gravitational
energy.
