Aim of the study: The aim of the work: to study the syncytial connections in the ganglia of the nerve plexuses of the large intestine. Material and research methods: The work was carried out on 30 sexually mature Wistar rats at the age of 3–4 months, having a mass of 180–320 g by the beginning of the experiment. The study used a universal method of impregnation, based on classical impregnation methods: intravascular — Rannier–Goyer and immersion — Bilshovsky–Gros. The study was conducted in 2019–2020. Results: According to our data, the large intestine has intraorgan ganglia located in the intermuscular and submucosal plexuses. The intermuscular plexus (Auerbach) of the large intestine has the form of a network with cells of various shapes and consists of nerve nodes containing cells of types I and II of Dogiel, however, the latter are numerically significantly predominant (20–25 cells or more). Syncytial connections of neurons in the autonomic ganglia of the intestine were constantly detected. These were syncytial connections of processes and bodies of two neurocytes. Protoplasmic processes of nerve cells diverge in different directions, go to meet similar branches, joining them, form a narrow or wide-looped network. Syncytial connections between the bodies of neurons and peripheral processes form closed annular anastomoses. Interfiber cytoplasmic bonds are formed by membrane syncytial fusion. Conclusion. The large intestine has intraorgan ganglia located in the intermuscular and submucosal plexuses. Syncytial connections of neurons in the autonomic ganglia of the intestine were constantly detected. Interfiber cytoplasmic bonds are formed by membrane syncytial fusion.
