Unformatted text preview: worry that activates the ANS and particularly the SNS. Adverse effects: ulcers, short/rapid breathing (asthma), the heart can get palpitations, bladder and urinary frequency These can all impact the blood vessels of the body. Typically, in the process of this there is a mental component that can aggravate the autonomic response. ANS Neurotransmitters and Receptors Long versus short preganglionic neurons. From the CNS all the preganglionic neurons produce Ach, and will terminate at nicotinic cholinergic receptors (fast) Postganglionic neuron is adrenergic Norepinephrine to epinephrine. Adregenic receptors are g- protein coupled, second messenger pathways. KNOW THESE. The adrenergic receptors will have different affinities for epinephrine, NE In the PNS the preganglionic neuron is also cholinergic, also going to interact with the nicotinic cholinergic receptor. In contrast with the SNS, the postganglionic effector cell are muscarinic. These are g- protein linked, no APs but some change that is mediated by a receptor. Modulation of expression can be different between...
