PHYSIOLOGY-AUTONOMIC NERVOUS SYSTEM-MAJOR AUTONOMIC RECEPTOR TYPES

Receptor Name:  Cholinoceptors: Muscarinic (M3) 

Locations in the body:  These are predominantly located on Exocrine glands where they mediate hormonal secretion, vessels (smooth muscle and endothelium) where they mediate vasoconstriction and vasodilatation. 

Result of Ligand Binding: CNS neurons Like M1 receptor-ligand binding
