Lecture 15 (Part 2): Innervation and Blood Vessels of Abdominal Viscera
Part 1 - Blood Supply (Slides 1-9)
| Slide | Topic |
|---|---|
| 1 | Title slide |
| 2-3 | Arteries of the gut (Foregut, Midgut, Hindgut) |
| 4 | Arteries of abdominal viscera; gonadal and renal arteries |
| 5 | Veins of kidneys, suprarenal glands, gonads |
| 6 | Hepatic portal system |
| 7-8 | Arterial supply to the anterolateral abdominal wall; superior and inferior epigastric arteries |
| 9 | Cross-reference to intestinal blood supply lecture |
Part 2 - Innervation (Slides 10-31)
| Slide | Topic |
|---|---|
| 10-11 | Innervation and dermatomes of the anterolateral abdominal wall |
| 12-13 | Overview: Extrinsic (CNS) vs Intrinsic (enteric) innervation |
| 14 | Control of abdominal viscera by CNS; visceral efferent (autonomic) and afferent fibers |
| 15 | Structural components: preganglionic/postganglionic fibers, spinal roots, rami communicantes, sympathetic trunk, splanchnic nerves, prevertebral plexus/ganglia |
| 16-19 | Sympathetic innervation - preganglionic fibers from T5-L3; Greater, Lesser, Least, and Lumbar splanchnic nerves; connections to Celiac, Aorticorenal, Superior and Inferior Mesenteric ganglia; function: decreases secretion/peristalsis, increases sphincter tone |
| 20-21 | Parasympathetic innervation - Vagus nerve (CN X) innervates foregut and midgut; Pelvic splanchnic nerves (S2-S4) innervate hindgut; function: increases secretion/peristalsis, decreases sphincter tone |
| 22-23 | Sympathetic trunks and splanchnic nerves (images) |
| 24 | Abdominal prevertebral plexus and ganglia |
| 25-27 | Sympathetic nervous system; autonomic innervation of GI tract; nerve fibers through prevertebral plexus |
| 28 | Enteric nervous system |
| 29-30 | Visceral afferent fibers; referred visceral pain (გადაცემითი ტკივილი) |
| 31 | References (Moore 7th ed.; Gray's Anatomy for Students 3rd ed.) |
- Sympathetic supply originates from T5-L3 spinal cord segments; preganglionic fibers form splanchnic nerves that synapse in prevertebral ganglia (celiac, aorticorenal, superior and inferior mesenteric). Effect: decreased GI motility/secretion, increased sphincter tone.
- Parasympathetic supply: Vagus nerve (foregut + midgut); Pelvic splanchnic nerves S2-S4 (hindgut). Effect: increased GI motility/secretion, decreased sphincter tone.
- The enteric nervous system (intrinsic) can function independently of the CNS.
- Visceral afferent fibers carry sensory signals that can produce referred pain (slide 30 even uses the Georgian term გადაცემითი ტკივილი).
