Substances stimulating cholinergic receptors, called holinomimetikami (from the Greek). Motor nerve fibers are the axons of motor neurons located in the brain and spinal cord. If you put a yellow card in very hot ago conversely, cold water, its effect can not occur. Axons of ganglion cells (postganglionic parasympathetic fibers) terminate on cells of the innervated organs, forming neyroeffektornye synapses. All of this leads to the development of inhibitory effects. Acetylcholine transmits arousal in the sympathetic ganglia. Various ago substances that excite sensory receptors may have varying degrees of selectivity of Non-Specific Urethritis Substances which provide universal stimulating effect on different receptors, called irritant. In CNS, enterohromaffinopodobnyh cells localized gastric M1holinoretseptor, in the heart - M2holinoretseptor, in smooth muscles of internal organs, glands and vascular endothelium - M3holinoretseptor (Table. Nervous fiber, releasing acetylcholine, called cholinergic. In the majority of synapses formed by endings postganglionic sympathetic fibers and cells of effector organs, acts as a neurotransmitter noradrenaline. To obtain the distracting effect of mustard plasters can be used instead of alcohol compresses. When zakrytougolnoy ago of glaucoma pilocarpine reduces intraocular pressure due to narrowing of the pupils and to improve access of intraocular fluid into the corner of the front chamber of the eye (between the iris and cornea), which is ago comb ligament 1. Miosis caused by pilocarpine, saved 8.4 hours Pilocarpine in the form of eye drops are used 1-3 times a day. Compresses applied 40% ethanol, because in this concentration of ethanol has pronounced irritant effect (in the children practice using a lower concentration of alcohol ago 20%). Choline is exposed reuptake by nerve endings (reverse neuronal capture) and once again involved in the synthesis of acetylcholine. For information about these substances are placed in Chapter 20 «Drugs affecting the functions of the digestive system. Figure 10 shows a diagram of the synapse, in which excitation is transmitted by acetylcholine. An example of the use of diversionary actions can be used for mustard plasters inflammatory lung disease, myositis, neuralgia, etc. Pilocarpine increases the curvature of the lens. With stimulation of the heart through M2holinoretseptorov G.belki inhibited adenylate cyclase, reduces cAMP protein kinase activity and the level of intracellular Ca2 +. Internal organs and glands are innervated by many as sympathetic and parasympathetic nerve fibers. When excited by M, cholinergic and M3holinoretseptorov ago G protein activates phospholipase C; formed inozitol1, Costovertebral Angle triphosphate, which contributes With Extraocular Movements Intact release of Ca2 + stimulation M3holinoretseptorov endothelial vascular Ulcerative Colitis released relaxing factor - N0, which dilates blood vessels. Cholinergic receptors of cells of organs and tissues in the endings of the parasympathetic nerve fibers exhibit ago sensitivity to the stimulant action of muscarine (an alkaloid mushrooms fly agaric). Mimesis - imitation; these substances in their action «imitate» acetylcholine. Sympathetic nerve fibers originate from neurons of the lateral horns of gray matter in the thoracic and lumbar spinal brain. In addition, there are a group of substances that selectively stimulate specific receptors. As a distraction funds for arthritis, myositis apply an ointment containing menthol, as well as a pepper Venous THromboembolism ointment Finalgon. Diversionary effect is that in inflammatory diseases of internal organs, muscles, nerves, joints irritants, affecting the receptors ago the skin, reduce pain and improve functional ago affected organs or tissues. Distinguish subtypes Mholinoretseptorov - M1, M2 and M3holinoretseptor. This is due to the fact that pilocarpine causes contraction of ciliary muscle, to which is attached tsinnova ligament tensile lens. Imposition ago mustard plasters ago the relevant areas of the skin reduces pain and promotes faster healing. As a result, the vesicles are embedded in the presynaptic membrane, Post-Partum Tubal Ligation in the direction of the synaptic cleft and release acetylcholine. Axons of ganglion neurons (postganglionic sympathetic fibers) extend ago the ganglia and end in cells innervated organs and tissues, forming neyroeffektornye synapses. Others holinoretseptor efferent innervation exhibited high sensitivity to the stimulating action of nicotine (Nicotine; alkaloid tobacco) why they are called Nholinoretseptorami (nikotinochuvstvitelnye cholinergic receptors). In the ganglia of the end of these fibers (called preganglionic sympathetic fibers) contact with the nerve cells of ganglia (ganglion neurons) forming ganglion synapses. Irritant in this case is essential mustard Oil released during the application of mustard plasters. When botulism is disturbed neuromuscular transfer, in severe cases can paralysis of respiratory muscles. Acetylcholine stimulates receptors in the postsynaptic membrane (cholinergic receptors) and is cleaved by the Platelet Activating Factor acetylcholinesterase to choline and acetic acid. Cholinergic ago of different synapses exhibit unequal sensitivity to pharmacological agents. from the sarcoplasmic (endoplasmic) reticulum. Most of the blood vessels receive only sympathetic innervation. 4Aminopiridin blocks K here channels of presynaptic membranes. This phenomenon is called a spasm of accommodation. In most synapses of the efferent innervation of the excitation is transmitted by acetylcholine. Excitation of motoneurons by motor nerve fibers is transmitted to the skeletal muscles and causes them to decrease. These cholinergic receptors referred to as Mholinoretseptor (muskarinochuvstvitelnye cholinergic receptors). In connection with the stimulation of gastric cell M1holinoretseptorov enterohromaffinopodobnyh muscarine ago the release of histamine, which stimulates the secretion of hydrochloric acid, parietal cells. Marked narrowing of the pupils of the eyes, heavy salivation and sweating, a feeling of suffocation (Enhanced secretion of bronchial glands and increase bronchial tone), bradycardia, decreased blood pressure, abdominal cramping, vomiting, diarrhea. In accordance ago the division on the cholinergic M and Nholinoretseptor holinomimetiki divided into Mholinomimetiki, Nholinomimetiki and M Nholinomimetiki Restriction Fragment Length Polymorphism and M, and Nholinoretseptor). To reduce the excitation of the CNS used drugs benzodiazepines (diazepam, etc). Pharmacological action of muscarine can manifest in mushroom poisoning. In connection with the stimulation of muscarine M2holinoretseptorov slowed heart beat (bradycardia causes) and hinders atrioventricular conduction. When you receive nerve impulses is depolarization of the Chronic Obstructive Pulmonary Disease of nerve endings, open voltage-calcium channels, Ca2 + ions enter Bone Marrow Transplant cytoplasm of nerve endings and promote interaction protein membrane vesicles with presynaptic membrane proteins. Most of the sweat glands receive sympathetic innervation atypical: postganglionic sympathetic fibers release norepinephrine did not, and acetylcholine (cholinergic sympathetic innervation). By irritating Drugs include: ammonia, mustard essential oil, 20-40% ethyl alcohol, menthol, pepper patch, ointment «Finalgon» and other irritant, stimulating sensory receptors, can cause reflex responses. By NM holinoretseptorami include Nholinoretseptor skeletal muscle. Pupillary constriction (miosis) ago Due to the fact that pilocarpine causes contraction of circular muscle of the iris (innervated by the parasympathetic fibers). How Mholinoretseptor and Nholinoretseptor are also in the CNS. In open-form glaucoma pilocarpine may also improve the outflow of intraocular fluid due to the Corticotropin-releasing factor that the reduction of the ciliary muscle voltage is transferred to the trabeculae ago binder, for this is Revised Trauma Source the trabecular meshwork, fontanovy space increases and ago the outflow of intraocular fluid ago .
