The features of histoarchitectonics of functional zones and segments in the lymph nodes of mature meat rabbits have been established on the example of Hyplus cross rabbits. Somatic lymph nodes of rabbits are represented by dense, compact formations, completely isolated, while visceral — a plurality of aggregations of different sized nodes that form packets or clusters in adipose tissue, without creating conglomerates. Lymphoid parenchyma is characterized by a pronounced morphological polarity, with an increase in its volume and density in the direction of the mouth of the tiny lymphatic vessels, with the formation, respectively, of a dense cortical and rarefied cerebellum of the nodes.

Parenchyma nodes are divided into segregated cortical sinuses and trabeculae segments or compartments. It is determined that for the segments of the lymph nodes the polar structure is characteristic, their extended pole is formed from the deep cortex units and located around these units of the lymph nodes, the opposite, more narrowed edge of the segment, constructed from brains and lymphatic spaces between them (medullar sinuses).On the periphery of the deep crust units, the lymphatic nodules are round-oval in shape, and in the region of the cerebral cords — round-cylindrical. The sine system is sufficiently developed, organized as an "irrigation system" that connects each vessel with a clearly defined functional compartment, forming wide labyrinths that are better expressed in the visceral lymph nodes, in the brain sines, which is probably associated with a more significant antigenic load. In the lymph nodes of rabbits, the basis of each lymphoid lobe is the centers of deep crust units with reactive centers of proliferation of T-lymphocytes, their periphery is represented by the lymphocyte transit zone and lymph nodes the deep crust units border with the cerebral cords.
