Question

Along with acetylcholine, you need to have an understanding of anticholinergic effects?

Has roles with both neuromuscular junction & Autonomic Nervous System? Is the primary neurotransmitter of the parasympathetic system (so what would you expect because of this?).

Answer 1

Introduction - Acetylcholine (Ach) is the major neurohu- moral transmiter at autonomic ,somatic as well as cernal neyrous site. cholino receptors: - Two class of receptors for Acetyl choline are recognised as muscarinic & nicotinic, the Former is G-protein couple receptor. Depending on type of receptor through ahich it is mediated the peripheral actions 1. Muscarinic ra Heart: Acetylcholine hyperpolarizes the SA nodal cells and decreases the rate of diastolic depolarization As a result, rate of impulse generation is reduced. 6) Blood vessels All blood vessels are dilated through only few skin, feice, neex & salivary glands.) fallin Blood pressure and Fushing especially in the blush area occur. c) smooth muscle - Smooth muscle in most organs is confected. Tone & peristalsis in the GI tract es increase and spincters are selaxed d) Eye confection of circular muscle of Iris is Formed. Also contraction of ciliary muscle can occur. 2. Nicotinic - @ skeletal muscles. The muscle endplate causes contraction of the Fibre. 3. CNS :. produce a complex ppattern of stimulation followed by depression in the formed of direct injection into brain

yes, Acety choline has a sole with neuromuscular Junctions I Hutonomic Nervous system becouse acetylcholine has Containing action of anfaction of smooth musces, that by the motor neurons of the nervous system releases to activate muscles contraction. In this manner acetyl choline affetts cholinergic system. In other hands a cedys choline also works as Prfenal transmitter for sympathetic & Parasympathetic nervous System. So is the primary neurotransmiter because the muscar) nic 19, receptors located on ganglion cells and enhal neurons, especially in cortex & corpus shatum. It plays La major role in medicating gastic seeretion, relaxation of lower esophageal sphincter on Vagal stimulation in learning, memooy & motor functions etc.
