[Structure and topography of the nucleus proprius cornus dorsalis of the spinal cord of horses].

The research article examines the structure of a part of the spinal cord in horses known as the nucleus proprius cornus dorsalis. The study discovered that these cells are consistently present in the lumbo-sacral region of the horse’s spinal cord.

Research Methodology and Findings

• The research was conducted on two horses’ spinal cords. This was done in order to study the structure and position of the nucleus of the dorsal horn within the spinal column.
• The findings indicated that the cells of the nucleus of the own dorsal horn were found throughout the sections of the lumbo-sacral part of the spinal cord.
• The nucleus is made up of two parts: the basal and marginal sections.
• The basal section consists of large and medium-sized cells which are situated in approximately two-thirds of the lower part of the grey matter of the dorsal horn.
• The marginal section of the nucleus consists elongated and spindle-shaped cells located alongside the dorsal margin of the grey substance of the dorsal horn.

Results Interpretation and Conclusion

• The researchers observed continuity of the nucleus in the lumbo-sacral region of the spinal cord was maintained, providing a consistent structure across this region.
• There were only instances of constrictions due to variations in the number of cells forming the nucleus in individual segments of the spinal cord.
• These differences in cell numbers likely contribute to the unique structure and functioning of these individual segments within the spinal cord.
