ANS&Anastomose EXAM3
Gross Anatomy - ANA & Anastomoses, Exam 3
| Question | 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) |
