Lymph nodes in hare (Lepus europaeus Pallas 1778). III. Lymphocentrum iliosacrale.

The majority of nodes of iliosacral lymphocenter are attached to the wall of a. iliaca communis dextra et sinistra from its origin to the rise of a. circumflexa ilium profunda. The total number of nodes of the lymphocenter ranges from 5 to 11, without any marked dextro-sinistral asymmetry. The size of nodes, as expressed by their length, showed a wide range from 1.5 to 20 mm and in more than one half of nodes it was 5 to 10 mm. The mass of individual nodes ranged from 1.7 to 98.9 mg and in one half of them was up to 20 mg. The total mass of all nodes of lymphocenter fluctuated individually from 131 to 340 mg with a slight asymmetry in favour of the right-hand side. Regarding a considerable positional variability of nodes the authors do not hold a further particularization of iliosacral lymphocenter for reliable and they consider the nodes under study to be a uniform topical group.
