| Sumario: | Studied, the origin and distribution of the sciatic nerve in 31 pig fetuses line Pen Ar Lan, 22 males and nine females, after being fixed in aqueous 10% formaldehyde. In these animals the lumbar vertebrae ranged from five to seven with a predominance of six, which have contributed to variations in the origin of that nerve. The sciatic nerve originated in antimeres 80.64% of the ventral branch of the fifth lumbar spinal nerve (L5) at 96.77 % of (L6),at 6.45% of (L7) in 100% of (S1) and 64.51% of (S2), The composition of the related nerve occurred in 45,16% of the animals for the union of L5, L6, S1 and S2, in 32.25% of L6, L5 and S1, in 12 90% of L6, S1 and S2, in 6.45% of L6, L7 and S1 and 3.22% L5, S1 and S2. There was symmetrical at the root in all specimens. This nerve gave branches to the glúteal muscles superficial, semitendinosus , semimembranosus and biceps femoris in all specimens, lesser frequency, to the twins muscles, quadratus femoris, adductors, gluteal medium, attachment, and deep. In 74.19% of the sample, there was a communicating branch with the pudendal nerve. No significant differences were found between the frequency of branches emitted to the muscles of both male and female antimeres. |
