Variations concerning the formation of femoral, obturator, and ischiatic nerves in dogs

In this research l92 dogs of different breeds, sex age and weight were examined. It was establiched that the femoral nerve did not have to be formed by connecting the ventral branches of the 4th, 5th and 6th lumbar nerves. Although it was the case in 73% of those examined, in 17% of cases the femoral nerve was formed by connecting the branches of the 3th, and 4th, 5 th lumbar nerves in 3% cases from ventral branches of the 3th, 4th, and 6th, lumbar nerves, and 6th lumbar nerves, and 5% of cases from ventral branches of the 4th, 5h, 6th and 7th , lobar nerves. In 2% of cases it was formed from th3 4th and 5th lumbar nerves. The obturator nerve in 64% of dogs was formed from ventral branches of the 4th, 5th and 6th lumbar nerves l8% cases from the ventral branch of the 4th and 5 th lumbar nerves and 10% of cases ventral branches of the 5th and 6th lumbar nerves. In 5% of dogs the obturator nerve was formed by connecting ventral branches of the 4th, 5th, 6th and 7th lumbar nerves, and only 2% of the examined dogs from ventral branches of the 55h, 6th and 7th lumbar nerves. In 80% cases the ischiatic nerve was formed by connecting ventral branches of the 6th and 7th lumbar nerves and the 1st and 2st sacral nerves. In 23% of dogs the ischiatic nerve was formed from the ventral branches of the 6th and 7th lumbar nerves and the 1st sacral nerve. In a considerably smaller number of cases the ischiatic nerve was formed from the ventral branches of the 7th lumbar 1st and 2nd sacral nerves. In 4% of cases, and 3% of the examined dogs it was formed from ventral branches of the 7th lumbar 1st sacral nerve. Simultaneously , in was formed from ventral branches of the 7th lumbar sacral 1st sacral nerve. Simultaneously, it was noted that the ventral roots which participated in the formation of the femoral nerve did not always have to participate in the formation of the obturator nerve.
