It is confirmed that the wall of the glandular part of the stomach and its interme-
diate zone is formed by the mucous membrane, muscle and serous membranes. Among them,
the most developed mucous membrane. It is covered by a simple cylindrical glandular epithelium.
The own plate is permeated with simple weakly branched glands. Muscular plate is well devel-
oped. The submucosa, as well as its own plate, is formed by a loose fibrous connective tissue.
It contains the lobes of the deep glands. In the area of the intermediate zone, deep glands are
absent. In the own plate of the mucous membrane of this area, the glands are inherent in the
muscular part of the stomach. Their secret on the surface of the mucous membrane forms a
delicate cuticle. The muscle membrane is formed by two layers of smooth muscle cells: the inner
skew and the outer circular.
Immune formation of the glandular part of the stomach and its intermediate zone is repre-
sented by a lymphoid tissue that is contained in its own plate and in the submucosal mucosa.
In the intermediate zone, the lymphoid tissue is mainly localized near the glandular part of the
stomach. Immune formation of the glandular part of the stomach and its intermediate zone is
morphofunctionally mature. Most of the lymphoid tissue of the glandular part of the stomach
and intermediate zone is its diffuse form, less secondary and primary lymphoid nodules, and the
least of them are , prenodules. The content of diffuse lymphoid tissue and secondary nodules is
greater in the intermediate zone, and the prenodules and primary lymphoid nodules in the glan-
dular part. The lymphoid nodules are predominantly round or oval and have the same dimen-
sions. The linear measurements of the intermediate zone nodules are much larger than those of
the glandular part, and the size of the secondary nodules is much larger than the primary ones. In
the intermediate zone in the muscular membrane, local concentrations of diffuse lymphoid tissue
are also detected around separate blood vessels, and in the subfamily of the serous membrane,
infiltration by lymphoid cells is observed.
Key words: goose, glandular part of the stomach, lymphoid tissue, lymphoid nodules
