Resumen

NUR, Ismail Hakki; PEREZ, William; KONIG, Horst-Erich  y  LINTON, Andrea. Origin and Distribution of the Lumbosacral Plexus Anatomy in Van Cats. Int. J. Morphol. [online]. 2021, vol.39, n.3, pp.848-857. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022021000300848.

The innervation of the pelvic limbs of the Van cat is investigated in this research. The origins of the nerves, the innervated muscles and nerve diameters were shown in a table. Five cat cadavers were used in the study. The pudendal nerve originated from the S1-S2 spinal nerves. The femoral nerve consisted of the ventral branches of the 5th and 6th lumbar nerves in 4 cats The ischiatic nerve was composed of the 6th and 7th lumbar (L6-L7) and S1 spinal nerves in all cadavers. The ischiatic nerve was the thickest branch of sacral plexus (the average diameter on the right side was 3.31 ± 0.27 mm and the average diameter on the left side was 3.28 ± 0.29 mm). The lumbosacral plexus was formed by the ventral branches of the L4-S3 spinal nerves. N.genitofemoralis consisted of only the ventral branches of L4 in all cadavers. N. femoralis did not give rise to a branch to the m. iliopsoas. N.plantaris lateralis was found to give a branch to the 3th finger. The quadriceps femoris muscles did not take any branches from either the ischiadicus nerve or the pudendal nerve. The obturator nerve did not receive any branches from the L4 spinal nerves. There was no branch to the skin from the caudal gluteal nerve. The thinnest nerve was the pudendal nerve. Due to the scarcity of studies on the lumbosacral plexus of cats, it is thought that this study will complete a gap in the field of veterinary anatomy.
