The Effects of Too Much Carbon Dioxide in the Blood. Excess CO2 can affect you just like a physical obstruction to breathing. Photo Credit Jupiterimages/Goodshoot/Getty Images. Carbon dioxide (CO2) is a gas that's always present in your blood. It is the waste product generated as your body uses up oxygen, and it is expelled from the lungs when you exhale.
Many neuropsychological conditions such as anxiety and depression are directly related to the imbalance of neurotransmitters. Common neurotransmitters include acetylcholine, dopamine, norepinephrine and serotonin etc.
Acetylcholine receptors and the autonomic nervous system. Acethylcholine acts on central and peripheral nervous systems (the latter is divided into somatic and autonomic). The autonomic nervous system (ANS) exerts its actions through its two antagonic branches: sympathetic (adrenergic) and parasympathetic (cholinergic).Looking the diagram below we can see that both sympathetic and parasympathetic branches are modulated at the preganglionic level by the neurotransmitter acetylcholine.nlike muscarinic receptors (which are G-protein coupled receptors), nicotinic receptors are ligand-gated ion channels. When bound to acetylcholine, these receptors undergo a conformational change that allows the entry of sodium ions, resulting in the depolarization of the effector cell.
