A 7-month-old female ostrich (Struthio Camelus) was studied. On the le
ft leg, muscles of the shank and foot were dissected and the right leg
was frozen and cut into slices for topographical examination. Some mu
scles and skeleton measurements were also noted. No trace was found of
the following muscles: M. plantaris, M. extensor hallucis longus, M.
extensor hallucis brevis, M. flexor hallucis brevis, M, adductor d. II
, IM. abductor d. II, M. flexor phalangis secundi d. III and M. adduct
or d. IV. Some interesting myological and topographical peculiarities
are specified concerning the 16 muscles mentioned, in order to provide
useful findings for surgically applied purposes: in case of locomotor
problems with leg deformities.
