Morphological sensory neurocyte parameters of the small intestine’s intermuscular plexus
Abstract
Background. The purpose of this work is to calculate the morphometric parameters of isolated Dogiel type II cells from the intermuscular plexus of the small intestine. Materials and methods. 3D models of oval-shaped Dogel type II cells from the intermuscular plexus of a rat (n = 1) were constructed and studied. Neurocytes were identified by the impregnation method on frontal and horizontal sections of the wall of the small intestine. Results. The results showed that the total number of nodes in the virtual model was 36534, and the mesh elements – 156595. The resulting 3D model of the cell and nucleus was reduced 900 times to obtain a three-dimensional cell and nucleus with absolute dimensions with a ratio of 1:1 to their true size. The volume of the Dogiel type II cell was 2785.11 μm³, the volume of the nucleus was 647.7 μm³ and the volume of its perikaryon is 2785.11 μm³. Conclusions. Digital type II cells from the intermuscular plexus of the small the intestine of rats has a three-dimensional structure of an ovoid shape. The cells are flattened in the transverse direction and elongated in the longitudinal direction.
