Sažetak
Researches was carried out on 135 pigs from the "Sljeme" farm in Sesvete during 1999. Difference in n. femoralis, n. obturatorius and n. ischiadicus were noticed in pigs with six and seven lumbal vertebra. N. femoralis emerged by connecting ventral branches of two final lumbal nerves in 65, 92% of pigs, equaly often in pigs with six (31, 11%) and in pigs with seven (34, 81%) lumbal vertebrae. Ventral branches of final lumbal nerves in pigs with six and seven lumbal vertebrae showed n. femoralis in 26, 66% of observed pigs, andsomewhat more often in pigs with seven lumbal vertebrae. N. obturatorius most frequently emerged from ventral branches of final lumbal nerves in pigs with six and seven lumbal vertebrae in 66, 66% of animals, and somewhat more often in pigs with seven lumbal vertebrae. Much more rarely it emerges from ventral branches of prefinal lumbal nerves more often in pigs with seven lumbal vertebrae. In pigs with six lumbal vertebrae, emergence of n. obturatorius from ventral branches of 4th, 5th and 6th lumbal nerves was noticed in 2, 96% of cases and from the ventral branch of 5th lumbal nerve in only 1, 48% of observed pigs. N. ischiadicus demonstrated the largest variation from the most frequently described emergence. In only 19, 25% cases did it emerge from ventral branches of 5th and 6th lumbal nerves and 1st and 2nd sacral nerves, and more rarely in pigs with seven lumbal vertebrae. It was observed most frequently in the ventral branches of the two final lumbal nerves and 1st sacral nerve (52, 58%), more often in pigs with seven lumbal vertebrae. Ventral branches of the final lumbal and 1st and 2nd sacral nerves participated in the emergence of 20, 70% cases, and somewhat more frequently in pigs with six lumbal vertebra. Emergence of n. ischiadicus from the ventral branches of the final lumbal and 1st sacral nerves was noticed, more frequently in pigs with seven lumbal vertebrae.
