Abstract

The appendix is a unique anatomical formation, which can be
found only in some mammalian species, including the rabbit. It belongs to
peripheral organs of immune system. Despite a significant number of experimental
studies aimed at establishing its functions, data on its morphology in the rabbit are
scattered and require refinement. The samples were obtained from 12 clinically
healthy males 4 months of age of the white Panon breed. The classical methods of
morphological research were used. The samples were fixed in a 6% neutral
buffered formalin solution and embedded in paraffin. Sections (8−10 μm thick)
were stained with hematoxylin and eosin, and according to Van Gieson. The
appendix differed from other parts of the cecum due to its form, diameter, color and
wall thickness. The mucous membrane occupied the largest area of the rabbit
appendix wall (94.68 ± 1,13 %). It contained lymphoid tissue, which was
represented by diffuse and nodular forms. The nodular form occupied 84.99 ± 3.71
% of lymphoid tissue, and the diffuse form – 15.01 ± 3.71 %.
