Answer |
| Sympathetic trunks continue inferiorly into |
sacral region (origin L1-L2) |
| ganglia provide |
sympathetic fibers |
| sympathetic fibers travel with |
branches of sacral plexus to lower limb |
| some visceral fibers leave chain & contribute to |
inferior mesenteric plexus (sacral splanchnics) |
| All parasympathetics in pelvic region from |
S2-S4 |
| fibers make up |
pelvic splanchnic nn. |
| visceral fibers not to be confused with |
nn. of sacral plexus originating from these levels |
| internal iliac a. has these arteries off it |
umbilical, sup. vesical, obturator, inf. vesical (male), uterine & vaginal (female), middle rectal, int. pudendal, inf. gluteal, sup. gluteal, iliolumbar, lat. sacral |
| iliolumbar anastomose with |
lumbar (from aorta) |
| lateral sacral anastome with |
middle sacral (from aorta) |
| inferior rectal (from internal pudenal) anastomose with |
superior rectal (from IMA) |
| uterine anastomose with |
ovarian (from aorta) |
