ANTR 350 1st Edition Lecture 25Outline of Last Lecture I. Sympathetic system responsesII. Parasympathetic divisionIII. Craniosacral IV. Parasympathetic functionsOutline of Current Lecture II. Plexus III. Autonomic plexusesIV. Referred painCurrent Lecture-plexus-a place where nerve fibers are unbundled and re-bundled for distribution-autonomic plexuses can contain sympathetic and parasympathetic fibers-autonomic plexuses-cardiac plexus– POST-/SYMP from cardiac nn. & PRE-/PARA from CN X-pulmonary plexus– POST-/SYMP from pulmonary nn. & PRE-/PARA from CN X-esophageal plexus– PRE-/PARA from CN X -abdominal Aortic Plexus– POST-/SYMP from prevertebral ganglia & PRE-/PARA from CN X -hypogastric plexusThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.– POST-/SYMP from aortic plexus & lumbar region symp. trunk & PRE-/PARA from pelvic splanchnic nn.-referred pain-pain that is perceived in a location that is distant from the origin of that pain.-results mainly from the fact that the GVAs from a given region enter the spinal cord at a level associated with specific GSAs.-the brain confuses the signal and you interpret the origin of the pain as coming from the area served by the GSAs-classic example is cardiac pain from angina that is perceived in the left shoulder and neck.-GVA from heart enters at T1 level spinal cord level-GSA from skin of dermatome of T1 also enters at T1 level-brain interprets GVA pain from ischemia as pain from the skin of T1
