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 is released from a presynaptic neuron into the synaptic cleft. Once in the synaptic gap, acetylcholine can: - Bind to presynaptic receptors: presynaptic activation or inhibition leads to automodulation of the presynaptic cholinergic neuron.- Be degradated by acetylcholinesterase: activity of this enzime on acetylcholine triggers its degradation into choline and acetyl coenzime A, thus terminating its effect. number of drugs target acetylcholine receptors, blockade of these receptors is associated with anticholinergic (parasympatholytic) effect, while stimulation causes activation of cholinergic (parasympathomimetic) effects. This articles overviews the key concepts on the pharmacology of acetylcholine receptors, such as:
