Abstract

The morphology of the spinal cord in 15 chickens, 15 ducks and 15 pigeons obtained from the Ankara region were examined. The spinal cord consisted of 15 cervical, 7 thoracic, 14 lumbosacral and 5 coccygeal segments (a total of 41 segments) in the chickens; 15 cervical, 8 thoracic, 16 lumbosacral and 5 coccygeal segments (a total of 44 segments) in the ducks and 13 cervical, 6 thoracic, 13 lumbosacral and 5 coccygeal segments (a total of 37 segments) in the pigeons. The cervical enlargement was composed of cervical segments 13-15 and thoracic segments 1-2 in the chickens; cervical segments 12-15 and thoracic segments 1-2 in the ducks and, cervical segments 11-13 and thoracic segments 1-2 in the pigeons. The lumbosacral enlargement in the chickens, ducks and pigeons included lumbosacral segments 1-12, 1-15 and 1-12 respectively. The rhomboidal sinus was measured. The central canal in the chickens, ducks and pigeons was located within the glycogen body at the lumbosacral segments 6-10, 5-11 and 2-9 respectively. The range of white matter and grey matter fields in the spinal cord segments was found using transversal sections of the segments schemes in all three species. The comparison of the morphology in segmental examination of the spinal cords was performed in the chicken, duck and pigeon, which belong to different groups of the bird family.
