Nicotinic acetylcholine receptor - Nicotinic acetylcholine receptors, or nAChRs, are ionotropic receptors that form ion channels in cells' plasma membranes. Like the other type of acetylcholine receptors, muscarinic acetylcholine receptors, their opening is triggered by the neurotransmitter acetylcholine, but they are also opened by nicotine (Siegel et ...
Muscarinic acetylcholine receptor - Muscarinic receptors are those membrane-bound acetylcholine receptors that are more sensitive to muscarine than to nicotine. Those for which the contrary is true are known as nicotinic acetylcholine receptors.
Acetylcholine receptor - An acetylcholine receptor (abbreviated AChR) is an integral membrane protein that responds to the binding of the neurotransmitter acetylcholine.
Hexamethonium - Hexamethonium is an nAch receptor antagonist (it blocks transmission at nicotinic cholinergic receptors by preventing the acetylcholine molecules from binding to the site of the R). Nicotinic receptors are so-named because of the agonistic effects of the drug nicotine at these sites.
Sensory Somatic System - ... responsible for muscle contraction. Sensory system - (See also sense) Sensory receptor - In a sensory system, a sensory receptor is a structure that recognizes a stimulus in the internal ... environment of an organism. In response to stimuli the sensory receptor initiates sensory transduction by creating graded potentials or action ...
