Document Summary

The names refer to branches of cranial nerves that carry parasympathetic fibres: vii: pterygopalatine (lacrimal, vii: submandibular (salivary, x: viscera (including lungs and heart, x: sacral (colon, bladder, sexual) Infor from hypothalamus travels to cells in intermediolateral cell column of spinal cord, then out to a chain of ganglia lying next to cord: a 1rst order sympathetic neuron in hypothalamus synapses on. 2nd order neuron in intermediolateral cell column of spinal cord. The second order neuron does one of 3 things: synapse on 3rd order neuron in sympa chain (the para- vertebral ganglia). [top pathway, right]: synapsing on 3rd order neuron in one of 4 pre-vertebral ganglia, 1. Inferior mesenteric: directly innervate neuro-endocrine cells of adrenal medulla. When stimulated, releases epi and ne directly into blood. Note: sympa and parasympa connections contain afferents and efferents, although we often just describe efferent function!
