Methods of examination of the vegetative nervous system Topic contents: Oversegmental formations of the vegetative nervous system – hypothalamus, limbic system (cingulate sulcus, hippocamp), reticular formation, amygdaloid nucleus. Segmental formation of the vegetative nervous system – Sympathetic section (thoraco-lumbar) - neurons of lateral horns C8-L2, ganglions, prevertebral nodes and plexes, Parasymthetic – vegetative nuclei of craniocerebral nerves – trunkal level, Sacral - neurons of lateral horns S3-S5, ganglions, plexes. Abnormalities of sympathetic section functions– Neurons of lateral horns – trophic abnormalities of skin, nails, osteomalacia Paravertibral ganglions – acute pain, (face, body, extremities), sympathalgia. Prevertebral nodes and plexes – pain onset in the stomach, spastic colon, dyskinesia of bileducts, solar plexitis etc. Abnormalities of parasympathetic section functions– Vegetative nuclei of craniocerebral nerves, sacral centers S2-S5. N.oculomotorius – exophthalmos, mydriasis, dilation of eye fissurae in affection of the nuclei of parasymthetic centers N.oculomotorius n.n.glossofaryngeus, n.intermedius abnormalities of taste, epiphora, salivation, depression of functions of cardiovascular system and respiration. n.vagus – depression of cardiac function and respiration in case of exclusion of n.vagus function. In the affection of the sacral centers – Atonic urinary bladder, actual enuresis, encopresis. In exclusion of central regulation there is a spastic urinary bladder, ischuria paradoxa, a reflex urinary bladder, imperative feeling of urination. Affection of the head and neck section of the sympathetic nervous system Central part – (Jacobson's spinal center - lateral horns – from С8 to Т2 segments) To differentiate – white connective branches, approaching to truncus simpaticus, and grey connective branches deviating from it. Nodes of boundary sympathetic trunk– Upper – passes the branches to the first – the fifth (1-5) spinal nerves, to the nodes of the tenth (10) pair of craniocerebral nerves, to thyroid gland, branches which form plexes around the carotid, around the external carotid, from the node to salivary glands, superior cervical cardiac nerve Medium - branches, which form medium cervical nerve Branches to the forth –the sixth (4-6) cerebral nerves and subclavian loop Lower – branches to the sixth- the eighth (6-8) cervical cerebral nerves, spine nerve, plexes of spine artery, branches to plexes of clavicular artery, lower cardiac nerve and branches to the organs of cardiac cavity. Symptoms – Prolapse of the function – ptosis, miosis, enophthalmos, anhydrosis and hypermimia of skin of face, neck, hands, thorax, sympathalgia. Irritations – exophthalmos, mydriasis, hyperhidrosis, angiospasm, temperature reducing of the skin of face, neck, hands, thorax, sympathalgia. Main section of the parasympathetic nervous system – Nuclei 3 pair (Yakubovych’s, Perlea’s), 9 pair (n.salvatorius), 10 pair (n.dorsalis n.vagi) Fibrae preganglionares – 3p. –short radices of the 3-d pair g.ciliare, 13 p. – n.petrosus superficialis major, chorda timpani, and tongue nerve. 9p. - – n.petrosus superficialis minor, 10p. – Fibrae preganglionares n.vagi Nodes - g.ciliare, g.pterygopalatynum, g.sublingualis submaxillaris, g.oticum, eztramural, intermural nodes of the organs of neck, thorax and stomach (n.vagi) Fibrae postganglionares - short ciliary g.ciliare, n.lacrimalis, nn.sublingualis, submaxillaris, n.auriculotemporalis, Fibrae postganglionares n.vagi.
